HOW TO MEASURE A BATTERY

HOW TO MEASURE A BATTERY. When looking to figure out the size of your lift truck battery, you will first need to calculate the volume of the battery for the correct sizing. Lift truck batteries are sized by their volume. To calculate the volume, simply multiply the length, width, and height of the battery as shown in the image.

Measuring Batteries Capacity and Battery Health Test

A battery''s capacity can be estimated relatively accurately using a set of measurements and some complex math, but the most simple way to measure a battery''s capacity is to measure the power going into or out of the cell. Power going into the cell would be charge testing and power coming out of the cell would be considered discharge testing.
