Answer 2

U can test it by the following ways -

1. U can make a simple circuit consisting of a bulb ,switch and wires connect the open end of the wires to the battery if the bulb glows the battery is excellent! bt if it's dim then battery is good and if it doesn't glow then battery is poor. U need to buy new one.

2. U can drop the battery from a height if it bounces many times battery is poor and if it doesn't battery is good.

Hope this helps u!!
