Frequently Asked Questions

What voltage battery tender do I need for my golf cart?

Most golf carts use either 6V, 8V, or 12V batteries wired in series to achieve 36V or 48V. If your cart uses six 6V batteries, you need a 6V charger for each battery or a multi-bank 6V charger. For carts with four 12V batteries, a 12V charger per battery works. Always check your battery voltage before purchasing.

Can I leave a battery tender connected to my golf cart all the time?

Yes, if the tender has an automatic float mode or maintenance mode, it can be left connected indefinitely without overcharging. Most modern tenders, including those in our guide, switch to a low-voltage float charge once the battery is full. Always verify the manufacturer’s instructions for continuous use.

How long does it take to charge a golf cart battery with a tender?

It depends on the battery capacity and the charger’s amperage. A 1A tender may take 24-48 hours to fully charge a deeply discharged 12V battery, while a 5A or 7A charger can do it in 4-8 hours. For maintenance, the tender will automatically adjust once the battery is full.

What is the difference between a battery charger and a battery tender?

A battery charger delivers a higher current to recharge a depleted battery quickly, then often stops. A battery tender provides a low, constant current to maintain a battery at full charge without overcharging. Many modern devices combine both functions with automatic switching.

Can I use a 12V battery tender on a 6V golf cart battery?

No, using a 12V tender on a 6V battery will overcharge and damage it. Always match the tender’s voltage to the battery’s nominal voltage. Some chargers are dual-voltage (6V/12V) and can be switched, but a dedicated 12V tender must only be used on 12V batteries.
