For example – On a full charge a good set of golf cart batteries will allow you to surely play a few rounds of golf. Using a 48 volt Club Car for example you can play a round of golf with a new set of fully charged batteries and after round is complete the cart will still be above the 48 volt threshold on the battery banks capacity. One because the start / stop load not very demanding vs all out start stops continuously without letting the golf cart or batteries catch their breath per se… Though this is also because a fully charged 48 volt cart with say 6x 8 volt batteries will be around 51 volts not 48 volts.
Why is my golf cart battery undercharging?

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.
Discharge Machine
The last method of testing a golf cart battery would be to use a discharge machine . They are often expensive and not practical for home use, but most dealers have one.
How to test golf cart battery?
To test the quality and power of a golf cart battery, you’ll need a voltmeter, a load tester, and a hydrometer.

How to tell if battery is capable of achieving voltage?
A drop between 1-2 volts is to be expected when performing a load test. If the voltage drops more than 3-4 volts though, it’s a sign that the battery is capable of achieving the necessary voltage but won’t maintain that voltage when a current is passing through it. If this is the case, replace your battery.
