How To Choose The Best Golf Cart Battery?

Both Gel Batteries and AGM Batteries are Sealed Lead Acid batteries. Basically, sealed lead-acid batteries are normal lead-acid batteries with something to seal up the mixture inside, preventing it from leaking. They have many advantages in common, such as deep-cycle capabilities, no-spillable design, can be used in different orientations, have a low self-discharge rate, require no maintenance, and also being vibration-resistant.

When choosing SLA batteries for golf cart, here are some things should be taken into account:

  • Capacity: When it comes to golf carts, you don’t need 100 Ah batteries (however, it’s great if you have ones). Small batteries of about 10 Ah would meet the need of the cart.

  • Cold-cranking amps: This is the ignition power to start the engine. Golf carts tend not to require much of ignition power. However, if you want to use the battery for other appliances, such as a 150cc scooters, you may need a battery that has cold-cranking amps of about 100A.

Which Brands Make The Best Golf Cart Battery?

Optima Batteries

Optima batteries is one of the biggest brand in the industry. They are the pure-power provider of streetcar champions, industrial uses, residential and recreational uses. They have three lines of batteries. The first is Redtop, which is for normal engine starting. The second is YellowTop, which is for heavy-duty electrical loads.

FAQs

Does this battery work with solar power?

Yes, as long as your solar system produces electricity.

Can I use mains electricity to charge this battery?

Yes. Charge the battery with a charger.

How long do golf cart batteries last?

You can expect they will last from 3 to 6 years, some may last for more than 10 years. The self-discharge rate is a meaningful number to tell you the longevity of the battery. The lower this rate is, the longer the battery will last.

Can you replace just one golf cart battery?

I would recommend replacing all the batteries at once since all six golf cart batteries work as a whole. If one or two batteries are bad, they will affect other batteries.

How long should you charge a new golf cart battery?

It depends largely on the capacity and the quality status of the battery. However, I would say that it is likely to take about 1-3 hours to fully charge a new battery; It is likely to take about 10 hours to fully charge a 5-year-old battery.

Conclusion

Above is my full review of the best golf cart batteries. I hope this article will help you find suitable ones for your golf cart.
