If you suspect your battery is unhealthy, there are several ways to test it: 1. Multimeter Test A multimeter is a simple tool that measures voltage. Here's how you can check a battery: Set the multimeter to DC voltage. Connect the probes to the battery terminals (red to positive, black to negative).
Compare the bounce to a battery you know is dead if you need help. Using a dead battery can give you a better frame of reference for the battery you're testing. Take a battery that doesn't work when you place it in a device. Then drop the two batteries next to each other and compare their bounces.
A healthy 12-volt battery should maintain a voltage range from 9.6 - 10.5+ volts under the load for 30 seconds straight. We don't expect you to run the starter for 30 seconds for starting batteries, so if you see the voltage meter drop within the voltage range and it sounded like a good strong start, then you probably just had a discharged battery.
A dead battery will bounce several times and fall over while a good one will drop and fall over without bouncing at all. Seriously, there's actual science behind this. According to electrical engineer Lee Hite, as a battery becomes discharged the manganese dioxide powder in it changes to manganese oxide.
There are many different types of batteries, and you can test all of them to see if they're charged or not. Alkaline batteries bounce when they're going bad, so drop one on a hard surface to see whether or not it bounces. Take an exact voltage reading with a multimeter, voltmeter, or battery tester to get an exact charge reading.
