STEP 3 Prepare a mixture of baking soda (2 parts) and distilled water (1 part). Mix the paste-like solution.
STEP 4 Dip your old or spare toothbrush in the baking soda and water solution. Then brush it on the battery terminals to remove any corrosion. If the corrosion is hard, you can use steel wool or sandpaper to have an extra abrasive texture in peeling off the corrosion.
STEP 5Grab your flat head screw and remove the battery caps. After, prepare the bucket and drain the old electrolyte solution into the bucket. Do the same thing for the other golf cart cells.

Frequently Asked Questions

For added information, I have included some FAQs regarding golf cart battery reconditioning and some related topics.


How to know if there is any problem with the charger or battery?
Frequently, it is the battery that is the problem and seldom with the charger. To know if the charger is not working, you can test it with another cell.

To examine if each cell has the right voltage capacity, use a voltmeter. Charge your battery to full capacity before reading its voltage with a voltmeter. If you are using a 6-volt cell, then the reading at full capacity must be within 6.2V to 6.3V. Getting a reading of 4V means you need to recondition it or replace it with a new one if there are any leakings or damages.

Can my charger still charge my golf cart cells if their voltage is low?
For automatic chargers intended for golf cart cells, it cannot charge if the battery is completely dead. If you have 36 volts for your golf cart battery set, then it must have at least 20V to 25V, for your automatic charger to recharge it back.

For a 48-volt golf cart battery set, it must retain 30V to 35V for your automatic charger to recharge it.

What is the estimated life of golf cart batteries?
On average, if there are proper maintenance and usage, the cells can last between 4 to 6 years.


How does low temperature affect golf cart batteries?
A low temperature can slow down the charge and discharge rate of any golf cart cells. Likewise, it decreases its charging capacity.
