Wrapping Up

There are several ways to check the strength of a battery. But you should stay safe by using the best protective gear and equipment.

The Basics

First, all batteries are not the same. So, for this purpose, we will stick to flooded cell lead acid batteries commonly used in golf carts. Testing other batteries such as AGM, Lithium, Gel or other battery chemistries may require specialized procedures which differ than those outlined here for lead acid varieties.

Symptoms

Possible symptoms of a failing battery or batteries could include the following:

Hydrometer

The first method of testing is to use a hydrometer, which measures the density of the electrolyte. This is accomplished through a specific gravity reading. Specific gravity is always compared to a baseline density of water, which is 1.000.

Load Tester

The second method of testing a golf cart battery would be to use a load tester . With more than 35 years of experience at our local shop, we have found that this testing method will often provide a more accurate result in a shorter amount of time. A battery load tester is a simple DC heating coil which is connected to a volt meter.
