8 Volt Golf Cart Batteries

Golf carts use 8 volt golf cart batteries, 12 volt or 6 volt battery packs to power their electric motors. 

The 8 volt golf cart battery is the most common in our golf cart community. Of course no golf cart runs on one battery like a car. They come in packs. Most battery packs are made up of 6 batteries. This means you would have a series of six 8-volt batteries connected in series (8 volts x 6 batteries = 48 volts). The total golf cart battery voltage for six 8 volt batteries is 48.

If you are thinking of getting a new Club car golfcart, they all use 8 volt batteries - 6 of them for 48 volts.

A new EZ Go electric golf cart will use either six 6V golf cart batteries for a total of 36 volts or four 12 volt batteries for a total of 48 volts.

You can tell if your golf cart uses 8 volt golf cart batteries by the number of cells or holes it has.  Each cell is equal to 2 volts.  Multiply the number of holes by 2 - as you can see with this Trojan golf cart battery there are 4 cells - 4x2=8.  So the battery pictured is an 8 volt golf cart battery.

Replacing 8 Volt Golf Cart Batteries

Replacing electric golf cart batteries is a major expense but is a part of golf cart ownership.  How often they need replacing depends on how well the golf cart was maintained, how it was used and the quality of the lead acid batteries. 

The cost depends on if you are getting well known brands like Trojan or Exide or cheap golf cart batteries.  Typically your well known brands will last longer so it may be worth the added expense if you plan on keeping your golf cart for several years. 

Trojan 8 Volt Golf Cart Batteries

All new Club Car golf carts use six 8 volt Trojan golf cart batteries.

Five out of the 6 golf cart dealers in our golfing community use the Trojan batteries. They all stated that they performed better and lasted longer than the Exide golf cart batteries.

I was told by one dealer that if the Trojan batteries are well maintained using only distilled water, you may see them last 6-8 years. But another dealer said you can expect a 4-5 year battery life with Trojan.

Trojan makes three types of 8 volt golf cart batteries. They are:

1. T-860 8V Deep Cycle Battery

2. T-875 8V Deep Cycle Battery

3. T-890 8V Deep Cycle Battery When you make your purchase:

1. Check the date code on the battery to make sure it hasn't been sitting on the shelf for a long time. This can seriously affect performance.

2. Ask about the warranty. How long is the warranty and does it replace the battery or just pro-rate the replacement cost of the battery.

48 Volt or 36 Volt - Which is Better?

According to my golf cart experts at Affordable Golf Carts, 48 volt batteries use 1/3 the amperage than a 36 volt. Golf carts with 48 volt batteries are more efficient.  From their experience,  a golf cart using  48 volts has a longer life than 36 volt batteries.

This is good news for me, because I just upgraded my 1987 Club Car that used six 6 volt batteries for a 2006 Club Car that has six 8 volt batteries.

Other popular makes of 8 volt golf cart batteries are Exide and U.S. Battery.  U.S. Battery boasts of their fast cycle up to full capacity, shorter charging time, and the batteries last longer.

Maintaining 8 Volt Golf Cart Batteries

Electric golf cart battery packs will last between 4-7 years depending on how the cart is used, if proper charging practices are followed, and if correct water levels are maintained.

Where to Buy 8 Volt Golf Cart Batteries

Living in a golf cart community there are several golf cart repair businesses that will replace your batteries. We have also used Batteries and Bulbs when our batteries needed to be replaced. 

Other deep cycle battery buying options may include your local Napa Auto Store or Lowe's Home Improvement store. Golf Cart Garage website sells them but the batteries cost more when you buy them on line. 

48 Volt Golf Cart Charger

Be sure your golf cart charger is compatible with the voltage of your electric golf cart batteries.

A cart with 48 volt batteries must use a 48 volt golf cart charger.  You cannot use a 36 volt charger to charge a cart with 48 volt batteries.
