If you want to know how to identify and fix a broken battery, here are some general guidelines. Give the battery a visual inspection to make sure there are no burn marks or signs of leaking fluid. Use a multimeter to check the voltage of the battery to make sure it's within the expected range of the battery.
Signs of a dead or dying battery include difficulty starting your car, dim headlights, a battery light on your dashboard, and a battery that’s old, leaking, corroded, or swollen. Jumpstart your car to recharge a dead battery. If it still won’t start or dies soon after starting, replace the battery or have a mechanic check the electrical system.
Use a multimeter or voltmeter to check your battery. Put either device on DC voltage if it's digital. Place the end of the black probe on the negative terminal and the end of the red probe on the positive terminal. Watch the readout on the multimeter. You should be looking at volts on your reader.
Alternatively, use a multimeter to test your battery by turning the knob to 20 on the “DCV” or “V” side. Touch the red probe to the battery’s positive terminal and the black probe to its negative terminal. You should have a working battery if the multimeter reading is close to the voltage written on the battery.
Another thing you can do is feel the battery to see if any particular spot is producing more heat than other areas of the battery pack. If after doing those things you feel like your battery might be bad, then you will have to tear it down enough to be able to measure the voltage of each cell group.
The ignition key should be off, and all lights and accessories should be turned off. Make sure the battery is clean and dry; moisture on top of the battery can cause false readings. Set the digital meter to DCV, connect the positive lead to the battery’s positive terminal and the negative lead to the negative terminal.
