How To Do Your Own Ezgo Golf Cart Battery Installation

Ezgo Golf Cart Battery Installation – with BatteryPete – S. Florida

Today I will be doing a basic golf cart battery installation on an older Ezgo Golf cart. This is really a straight forward job nothing difficult here – maybe just lifting the batteries themselves in and out of the cart during the installation process. Though we will want to look over the golf cart first because with older carts you will want to check over the battery bank and all connections for corrosion and deterioration. To ensure good performance you will always want to replace all cables that need it.

Getting started with an EZGO Medalist or Txt

The EZGO Medalist and Txt carts are based on a 36 volt battery bank. Consisting of six 6 volt golf cart batteries. We will be installing a new set of our PowerPro Golf Cart batteries. One of the few batteries available today that are still manufactured in the good ole’ US of A. PowerPro batteries offer great value and performance at a reasonable price. (Comparable to the Trojan T-105) with 215Ah at 6 volts. Or even the 232 Ah US Battery – us2200xc 6 volt golf cart battery we are replacing in this case. US Battery makes incredibly strong batteries. But no matter how good your golf cart battery might be – unless taken care of and proper voltage is maintained with your golf cart battery charger the life expectancy of that battery system is severely limited.

Begin with a Test

I always start with a quick golf cart battery test of the system in general. Overall voltage available, then voltage of each individual golf cart battery. While testing voltage I can also run a load test on each golf cart battery. Technically a 6 volt battery should register 6+ volts on the meter, and when placing a 200 Ah load on the battery it should maintain at least 5 volts for 10-15 seconds. This will determine the internal state of the battery in question. If it performs as mentioned the battery is good. I use this cheaper old school load tester for several reasons. One being I can adjust the load applied based on battery being tested. (Most small load testers will only apply about 50-60 amps to the battery at the flip of the switch. Secondly it has two separate meters, one for voltage and one for Amps applied. Lastly they are affordable – old school load testers have a relatively short life span when testing as many batteries as I do.

Making the change

Once I determine the batteries are in need of replacement I begin the relatively straight forward process.

Check for Corrosion

First I will make note of any obvious connection issues. (Battery Cables or terminals with corrosion or defect) Replacing anything that does not look fit for continued use or if I feel it will affect the performance of the cart. Pete’s Golf Carts offers golf cart battery cable kits for all popular models. Bad connections or wire corrosion account for approx. 1/3 of the usual complaints from customers mentioning cart speed issues or available time in service between recharging.

Getting to the battery

Then I remove the retaining system, in this cart’s case it is just the basic plastic spacer/retainer hold down. Secured by two nuts usually 9/16′. Next I will advise you to take your cell phone and snap a few pictures of the battery bank. This will help you in the re-install phase placing the battery jumper cables in the correct location. After you have done so, proceed to remove the cables connecting the batteries to one another. I will also suggest you lay them out on the ground in the general lay out they are placed on the batteries. Granted they are in good condition and do not need to be replaced. Next you can begin pulling out the old batteries. Once complete I will inspect the battery area and frame for obvious signs of leakage and corrosion buildup.

Watch out for acid

If any I will rinse off with a garden hose to dilute any remaining battery acid. Then after I am satisfied the area is clean, I will let dry then apply a corrosion treatment to coat the frame. This will help offset the continued corrosion process that is inevitable. This is one major design feature with an EZGO that people shy away from – Steel frame – vs the Club Car Aluminum Frame design.


Next I will begin to install the new batteries, and reconnect the battery cables to their respective locations. After doing so I will also apply a corrosion preventative to the terminal connections on each individual battery.

This will help deter nature’s elements from setting in and creating a mess or making for bad connections over time.
