How do you kill a battery?
The first and most reliable way to kill a lithium battery is simply to charge it too much. Charge it above 14.6V and rapid cell damage will occur. Resulting in a short circuit in the weakest cell, which then rapidly increases voltage across the other cells.
What causes a car to draw power from the battery?
Learn more… If your vehicle is drawing power from the battery and all of the lights and other electrical components are off, you might have a parasitic battery drain (or draw). Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle.
What to do if your car battery is draining?
Assuming that the cause of the battery drain is not human error, you will need the assistance of a qualified mechanic who can diagnose your car’s electrical problems and determine if it’s a dead battery or something else in the electrical system.

What should the parasitic draw be on a car battery?
For testing purposes, we will select 2A or 200mA in the amp section of the meter. This is where we can see the parasitic draw on the battery. The reading for a normal vehicle with no parasitic draw can range from 10mA to 50mA, depending on the manufacturer and the amount of computers and features the vehicle has.
