Batteries start bat. START command - launch application in a new window
Three batteries from new batteries - small, light, with a huge capacity ... provided the Pioneer with lighting, heating, propulsion ... for a continuous fifteen-day submerged transition ...
G. Adamov. "Secret of Two Oceans"
It is unlikely that the great science fiction writers of past years expected that they would fail with a seemingly reliable topic -. Or rather, with the lack of the power that they unanimously predicted. But the tasks of the batteries, which we decided to test in the next annual examination, are much more mundane: to turn the starters and help the generators. This time we are checking the “Europeans”, which fit into the dimensions of 242 × 175 × 190 mm. Different manufacturers fit into this volume of over eight liters the declared capacities from 60 to 66 Ah. In total, we purchased 28 batteries in company stores: with receipts, guarantees, etc.
It remains to compare their actual power-to-weight ratio. This is where modern fantasy begins ...
Judge for yourself: the spread in the initial reserve capacity is 17-fold. The mass indicated on the label for some reason exceeds the true one by kilograms. And five batteries were afraid of the Russian frost of three dozen degrees!
No, science fiction writers were clearly optimists. But our numbers are real.
The measurements were carried out by specialists from the NIITs AT 3 of the Central Research Institute of the Ministry of Defense of Russia. The test results refer to a specific sample of batteries and are not general criteria for their quality.
HOW THE POINTS WERE ALLOCATED
According to the results of the measurements recorded in the protocol, points were assigned: in each type of test, the best and worst results were taken, assigning them 5 points and 1 point, respectively. All other participants received intermediate points according to the position they took between the leader and the outsider. For example, if when measuring the reserve capacity, the leader showed the result of 124 minutes, and the outsider - 81, then the participant with the result of 105 minutes received 3.23 points. And so - for all five types of tests. The final score is the arithmetic mean of five intermediate marks. We did not introduce weight coefficients that increase the significance of one parameter in relation to others: all parameters were recognized as equivalent. The figures given by us allow anyone who wishes to make their own calculations. It is clear that the arrangement of places in this case will definitely change.
Reserve capacity
Shows how long a car will last if the alternator has failed. The expert will say differently: in how many minutes the voltage at the terminals of a battery that delivers a current of 25 A to the load drops to 10.5 V. Measurements are carried out at a temperature of 25 ° C. The higher the score, the better.
The best result was shown by MULTI: 124 min.
Worst - avtoSil: 81 min.
Reduced starting energy with declared current
Characterizes the energy of the battery in the starting mode. The test is carried out at -18 °C. First, the battery is discharged with the declared cold scrolling current Ixn for 30 s, then the voltage U30 is recorded at its terminals. After a pause of 20 s, the battery is discharged with a current equal to 60% of the declared Ixp until the voltage at the terminals drops to 6.0 V. The discharge time t6 is recorded. The reduced starting energy is calculated by the formula:
E \u003d 0.3I xp (U 30 - 6.0) t 6
The higher the score, the better.
The best result - MEDALIST: 28.21 kJ.
The worst - "Kursk Accumulator" 6 ST-60N: 10.37 kJ.
Reduced single current starting energy
Allows you to compare the current characteristics of all batteries in the same conditions, regardless of their passport data. The test is carried out at -18 °C. First, the battery is discharged with a current of 450 A for 30 s and the voltage U30 is recorded at its terminals. After a pause of 20 seconds, the battery is discharged with a current of 270 A until the voltage at the terminals drops to 6.0 V. The discharge time t6 is recorded. The reduced starting energy is calculated by the formula:
E \u003d 135 (U 30 - 6.0) t 6 .
The higher the score, the better.
The best result - MEDALIST: 34.73 kJ.
The worst - "Kursk Accumulator" 6 ST-60N: 6.86 kJ.
Reduced single current starting energy at -29 °C
Similar to the previous tests, the difference is only in temperature. The higher the score, the better.
Best result - VARTA: 8.85 kJ.
The worst - "Kursk Accumulator" 6 ST-60N, START. BAT, "Podilsky accumulator" 6 ST-62N, ACDelco M62-H3, Energizer PLUS EP60-L2X:
they all gave up before the end of the test.
THE REAL ENERGY CAPACITY OF NEW BATTERIES DIFFER 17 TIMES. SHAME TO SELLERS!
Reduced single current starting energy after vibration test
Vibration resistance is an indicator of the quality of the assembly of the product.
The batteries are mounted on a wooden pallet at the back of a heavy truck and shaken for 16 hours on cobblestone. RMS value of vibration accelerations in the frequency range of 0.7–22.4 Hz is 2.77–4.29 m/s².
Measurements of current characteristics are carried out according to the method of the previous paragraphs. The higher the score, the better.
The best result is a-mega Innovative Hybrid 6 ST-60-A3: 34.82 kJ.
The worst - "Kursk Accumulator" 6 ST-60N: 9.33 kJ.
WELL FORGOTTEN NEW
A well-known saying takes on a new meaning on the basis of batteries. You pay the seller for a new battery, and then you find out that you have been sold a product that has been sitting in a dusty warehouse for a long time. With a guarantee and other papers, but at the same time discharged obscenely. Therefore, before starting the tests, we without fail charge all the batteries! And their reserve capacity at the time of purchase is given in the table for reference only: they say, people know what rubbish they can slip you. But this parameter does not participate in the distribution of seats.
"FOR EINSTEIN'S HORRIBLE THEORY"
Vysotsky sang about the change in the course of time, but we observed the change in mass. Almost all samples are much lighter than the label says! We leave the interpretation of this fact to the manufacturers. Our option: banal lead savings. And those who do not indicate the mass, were, as it were, not in business. As they say, be silent - you will pass for a smart one ...
WHERE TO FLY FOR THE BATTERY
Fantastic fiction, but how to choose? Persistently looking for the next Zarulevo winner in the store? If you do not want to contact the service or the help of the seller, then the algorithm is as follows. You need to take the one that will fit in the niche allotted to it, whether it be the engine compartment, trunk or something else (it’s stupid to miss a couple of centimeters). Along the way, we determine the polarity by looking at the old battery: what is on the right and what is on the left. Of course, if the car is not European, then the terminals themselves may differ from most of the usual ones both in shape and location. After that, we choose a brand: here we definitely advise you to be guided by the list of our winners of recent years and never peck at newcomers or outsiders. Even if they have beautiful labels.
The brand of the battery determines, as a rule, its price. The declared current and capacity will turn out by themselves - based on the dimensions. We charge the battery, connect it instead of the old one - and the key is to start!

Korea
Estimated price, rub. 4200
Declared capacity, Ah/min 62 / 100
Declared current, A 510
Weight with electrolyte, kg 14,38
The most expensive battery in the test disappointed us. It is cold in Russia in winter, and you have to work in the cold, and not give up after 21 seconds, that is, at the very first stage of measurements. The rest of the results were not impressive either.
19th place Energizer PLUS EP60-L2X
Johnson Controls
Estimated price, rub. 3600
Declared capacity, Ah 60
Declared current, A 540
Weight with electrolyte, kg 14,31

Tyumen
Estimated price, rub. 3000
Declared capacity, Ah 62
Declared current, A 500
Weight with electrolyte, kg 16,76
The heaviest battery in our test, as always, did not disappoint, confidently pushing out two dozen competitors. Fifth place in terms of reserve capacity, confident performance in the cold - in general, everything is fine. It is a pity that the usual low Tyumen price is a thing of the past.
7th place BOSCH SILVER PLUS S5
Germany
Estimated price, rub. 3800
Declared capacity, Ah 63
Declared current, A 610
Weight with electrolyte, kg 14,92
Usually Bosch batteries declare modest currents, but here - 610 A! During this test, fourth place was won - very good. Moreover, the battery is quite light. In general, the performance is typical for the brand: the place is quite high, but not prize-winning.

Declared capacity, Ah 64
Declared current, A 550
Weight with electrolyte, kg 15,66
"Sibiryachka" became the third in the test of the reserve capacity and the fifth in the test with the declared current. Very well. One thing is not clear: why, when weighing, kilograms were missing from the promised mass? Maybe he was not enough to be in the top three winners?

Declared capacity, Ah 62
Declared current, A 600
Weight with electrolyte, kg 15,16
This battery, as always, fought only for gold, but ... The reserve capacity failed - only the seventh result. As a result, even the usual victories in the tests with the declared and single currents did not help to climb back to the top of the pedestal. But the highest class of the brand is confirmed: “Medalist” is the vice-champion!
1st place VARTA BLUE dynamic D43
Johnson Controls

QUESTION ANSWER
- Why do batteries, when tested, give out the declared current for so short a time? If the capacity is 60 Ah, then arithmetic suggests that a current of 600 A should be generated for approximately 0.1 hours, or 6 minutes. But the real count goes only for tens of seconds ...
The fact is that at this current, the battery capacity is no longer 60 Ah, but much less: about 20–25. The inscription "60 Ah" only says that for 20 hours at a temperature of 25 ºС you can discharge your battery with a current of 3 A (60:20), and no more. At the same time, at the end of the discharge, the voltage at the battery terminals should not fall below 10.5 V.
Estimating capacitance in ampere-hours is very inconvenient. And to measure it in these units is simply illiterate: the product of current and time does not give capacity, but the amount of electricity, which is otherwise called charge. The unit of quantity of electricity is the coulomb. 1 C = 1 A s. Accordingly, 1 Ah = 3600 C. The term “reserve capacity” is much clearer, showing how many minutes the battery will last on a car that has a failed generator.
- Is it true that when installing a battery with a larger capacity than the standard one, it will not be charged, and the starter will fail due to excessive current?
Not true. What will prevent the battery from being fully charged? Here's an analogy for you: if you scooped up a glass of water from a bucket or barrel, then to restore the initial level of liquid, you will need to add the same glass from the tap - both into the bucket and into the barrel. As for the expected breakdown of the starter, its current consumption will not change, even if the battery capacity increases by a hundred or thousand times. Ohm's law does not depend on ampere hours.
Talk about future breakdowns is only appropriate for extreme people who are used to getting out of the swamp on the starter. At the same time, the latter, of course, gets very hot, and therefore a low-capacity battery can save it from fatal overheating, dying first ... But this is a hypothetical case.
THE BATTERIES AT THE FACTORIES DO NOT REPORT LEAD. WHO IS GUILTY?
- Is it possible to assess the condition of the battery by the voltage at the terminals?
Approximately possible. At room temperature, a fully charged battery, disconnected from loads, should provide at least 12.6-12.7 V.
- What is hidden behind the term "calcium battery"?
The Ca (or even Ca-Ca) badge on batteries is increasingly present today. We are talking about very small (fractions or units of a percent) additions of calcium to the alloy from which the plates are made. If it is added to both positive and negative electrodes, then the same Ca-Ca is obtained. Such batteries, other things being equal, boil more difficultly, which is important for maintenance-free batteries. They also have less self-discharge during storage. Therefore, batteries with additives of traditional antimony (they are usually given out by the presence of traffic jams) are almost never found on sale today.
FIVE BATTERIES DID NOT RESIST THE FROST!
- Why choose a battery with a declared current, say, 600 A, if the real need is half as much?
The declared current is also an indirect indicator of the quality of the battery: the higher it is, the lower its internal resistance. In addition, in severe frost, the oil thickens and the current increases.
- Which is better - serviced batteries or maintenance-free?
Batteries that still have access to banks are gone. Such products - let's call them serviceable - are best suited for old machines with unstable mains voltage, in whose batteries the water can boil away. For a modern car, this is superfluous: they simply put a new battery under the hood and forget about it for several years. Note that in a new car, it doesn’t cost anything to ruin the battery in a week. Night winter starts, a full set of included energy consumers, short runs in traffic jams - under such conditions, it does not have time to recharge from the generator and slowly dies.
Team START allows you to run applications in a separate window, with the ability to specify some parameters for their execution.
Format command line:
START ["header"] [command/program] [options]
Command line options:
"header"- window title. Required in double quotes.
path- working directory.
B- launching the application without creating a new window, disabling processing of the CTRL+C key combination. If the application does not handle the CTRL+C key combination itself, the only way to break it is to use the CTRL+Break key combination.
I- The new environment will be the original environment passed to cmd.exe, not the current environment.
MIN- Run a command/program in a minimized window.
MAX- Run a command/program in a maximized window.
SEPARATE- Run 16-bit Windows programs in a separate area of memory.
SHARED- Run a 16-bit Windows program in a shared memory area.
LOW- Run application with IDLE priority (lowest priority).
NORMAL- Run application with NORMAL priority.
HIGH- Run application with HIGH priority.
REALTIME- Run application with REALTIME priority (highest priority).
WAIT- Launching an application and waiting for its completion.
ABOVENORMAL- Run application with priority class ABOVENORMAL (above default)
BELOWNORMAL- Start application with BELOWNORMAL priority class (below default)
command/program- If it is an internal cmd.exe command or a batch file, the command handler (cmd.exe) is started with the /K switch. This means that the window will not be closed after the command completes. If it is not an internal cmd.exe command or a batch file, then it is a program that will run in a graphic or text window.
options- Parameters passed to the command/program.
Invoking non-executable files through the file type association mechanism is as simple as typing the file name on the command line. For example, the command
START MYFILE.TXT
Will launch a text editor NOTEPAD with the opening of the MYFILE.TXT file. See the descriptions of the ASSOC and FTYPE commands for information on creating such mappings from batch files.
When running a 32-bit GUI application, the CMD.EXE command handler does not wait for the application to exit before returning to the command prompt. This new behavior does NOT apply to running applications from batch files.
When executing a command line whose first element is the text string "CMD" with no extension file name or specifying a path, it is replaced by the value of the COMSPEC variable. This prevents start cmd.EXE from the current active folder, if there is one.
If the first element of the command line does not contain a filename extension, the CMD.EXE command handler uses the value of the PATHEXT environment variable to determine the executable filename extensions and the search order for the desired file. By default, the PATHEXT variable is set to:
COM;.EXE;.BAT;.CMD
Note that this syntax is similar to the syntax for the PATH variable, that is, individual items are separated by semicolons.
If the search for an executable file does not match any of the extensions, a match is made against the specified folder name. If the folder name matches the specified one, then the START command starts the EXPLORER for that path. If such an action is performed from the command line, then it is equivalent to executing the CD /D command for the specified path. So, for example, the command
start C:\windows
Opens the C:\windows folder in an explorer window.
Examples of using:
start/?- issue a certificate about the use of the command.
start- when run without parameters, a new CMD command interpreter window will open.
start "My new CMD window"- as in the previous case, CMD will be launched in a new window, but text will be displayed as the title of the window My new CMD window
start devmgmt.msc- run on extension .msc Windows Device Manager.
start http://google.com- the Internet browser will be launched and the page of the Google search engine will open.
start mailto: [email protected] - the mail client will be launched in the mode of preparing an email for the address [email protected] .
start /min notepad.exe- Notepad will be launched in a minimized window.
start "Backup Files" /min /belownormal mybackup.bat- run a batch file in a minimized window with reduced priority.
start /abovenormal /MAX winword.exe- launching the Microsoft Word editor in a new window, expanded to full screen and with increased priority.
start "" /high /MAX "C:\Program Files\Good game\MyGame"- start the program my game with high priority.
Priority management is convenient to use to ensure the user's comfortable work with interactive applications against the background of long-term computational tasks. So, for example, equal priorities of the MS Word editor, and a calculation task that consumes a significant share of the CPU resources, the effect of freezes may occur when working with text document. Reducing the priority of the calculation task will create normal conditions for the user to work against the background of her work.
Please note that the window title can be omitted, but the peculiarity of processing input parameters by the command start may produce unexpected results when trying to run a program whose name or path contains space(s). For example, when you try to run the following command:
start "C:\Program Files\FAR\FAR.EXE"
Due to the presence of a space in the path to the executable file, the string to run FAR.EXE must be enclosed in double quotes, but the format of the input parameters for start assumes the presence of a window title, also enclosed in double quotes, as a result of which "C:\Program Files\FAR\FAR.EXE" is interpreted not as an executable program, but as a window title - the interpreter will be launched cmd with the window title "C:\Program Files\FAR\FAR.EXE" . In order to prevent this from happening, you need to use any, even empty, header:
start "" "C:\Program Files\FAR\FAR.EXE"
When running batch files with the command start, the command interpreter window (cmd.exe) is launched with the parameter /K, i.e., after executing the commands in the batch file, cmd.exe does not terminate. For example, there is a batch file test.bat the following content:
ECHO TEST
When launched with the command start test.bat will be fulfilled echo and the shell window will remain open, waiting for user input. This fact must be taken into account when using the command start in scenarios that run automatically without the intervention of a human operator. To close a window cmd after executing the batch file, it is enough to add the command to its end EXIT.
