Used Forklift Battery Buying Guide

Not sure what size battery you need? Here are a couple easy ways to find out.


The easiest way to replace a forklift battery is to determine what battery model you need.  Battery models use three numbers such as 24-85-21 or 12-85-9.


You can look for the battery model on the battery data tag.  If you cannot locate the battery data tag or it has been removed, check underneath the plastic caps covering the terminals. Usually the serial number and model number is stamped on one of the terminals near the positive, or red, cable.


If these methods fail, take very precise dimensions (length x width x height) and read the forklift data tag to find out what voltage your forklift uses, then give us a call. We can help you figure out what size you are looking for and provide you with a competitive quote.


Curious what the model numbers mean?


The model of an industrial battery consists of 3 numbers separated by hyphens like the model numbers listed below. The first number is the number of compartments or cells in your battery. Doubling that number gives you the voltage. EX. 18-85-21. 18 cells = 36 volts.


The second and third numbers indicates the amp hours of your battery. You subtract 1 from the third number and divide it by 2, then multiply that by the second number to get your amp hours. EX. 18-85-21. 21 – 1 = 20. 20/2 = 10. 10 * 85 = 850 amp hours.
