FAQs

How long do 12V golf cart batteries last?

An estimate would be around 4-5 hours provided that the battery is fully charged.
And usually the service life is around 5 years for any of the golf cart batteries but some may also last for 8 years.

Is there a difference between deep cycle and marine battery?

Usually all marine batteries are deep cycle batteries but it is not important for a deep cycle battery to always be a marine battery.
These two are different terms for batteries but not different types of batteries.
A deep cycle battery can run long hours and needs to be charged regularly whereas a marine means that the battery is most suitable for marine applications.

What does ‘deep cycle’ mean on a battery?

Deep cycle batteries are the opposite of starting batteries. Deep cycle batteries provide constant current throughout and cant be used as a starting battery. Deep cycle means it can run constantly for hours.

What happens if a deep cycle battery goes flat?

If your deep cycle battery goes flat after a deep discharge then you should try to recover it by charging with a high voltage battery charger.
