Put a test light between the negative cable and the negative battery terminal. With the key out of the ignition switch and the vehicle just sitting there (make sure the doors are closed) the test light should not light up bright. If it does, there is a draw! Disconnect one fuse at a time until the test light goes out. When it does, you have found the circuit that the draw is on! Here is a hint... The amperage battery drain test requires disconnecting one of the battery cables. If your car radio or alarm system needs a code to reactivate it after cutting battery power, make sure you know the code to …

The ONLY way to test a battery is to estimate the current draw scenario, and 200mA is a good base case scenario, and test it with an equivalent load. When you test a battery unloaded you can get nearly the full "new" voltage on a battery with very little capacity left. Just use a 1/2 watt (or greater) resistor as a load and you can get a true estimate of whether the battery is good or bad.

LiPo Batteries How to choose the best battery for your
18/11/2008 · The current draw on your battery is probably a lot less than 10 amps but keep in mind this is probably the maximum a less expensive volt meter is going to measure. Your car battery, again, is capable of pushing much more current. Sorry if I scared you. I guess all I'm saying is be very careful. I'm sure those with more experience can give some better opinions than mine.

How To Test Battery Amps Draw

18/02/2009 · Best Answer: Use the highest amp setting on the multimeter (usually 10A) and it will show up. If it is drawing more than .5 amps, there is a draw. You can do this with an automotive test light too, if the light is out, or very dim, you are fine, and if it is bright, you have a draw. Check the obvious first

  • If a battery had 10 amp hours and you had a 1 amp draw (say a weak light) it would be able to run the light for 10 hours. If you were to use a 5 amp light the battery could run the light for 2 hours. If you multiply the amp hours by the voltage you will get watt hours.
  • BU-902a: How to Measure CCA. Discover why a good CCA reading does not always guarantee a good battery Ever since Cadillac invented the starter motor in 1912, car mechanics have explored ways to measure cold cranking amps (CCA).
  • Amps measure power, while amp-hours measure capacity (actually Watts and watt-hours measure power and capacity, but those are simply amps*volts (or amp-hours*volts), or amps*48 in this case). The controller will not burn out as it will only ever draw up to 20 amps from the battery.
