Battery tips

How-to and maintenance for lithium and lead-acid golf cart batteries.

Bedrock 48V 105Ah lithium golf cart conversion kit

Charge before you water

Charging raises the electrolyte. Fill first and the acid overflows onto the tray when the charge finishes. Match the cart by make, model, year, and voltage…

Water is not a charge

Adding water does not put amp-hours back. A cart that died on the path needs a charge, and it may need a set. Match the cart by make, model, year, and…

Charging a fleet in rotation

Rotate carts onto a finished charge. A fleet lead pack that never finishes will sulfate in unison. Match the cart by make, model, year, and voltage before…

A lead string fed lights and the horn from a tap. One lithium battery has no tap. The converter makes 12 volts from the pack. Match the cart by make, model…

Terminal styles on a lead-acid set

Match the post to the lug you have. Interstate listings let you choose on most models. Match the cart by make, model, year, and voltage before you order.

Battery hold-downs

A battery that can move will crack a post on a bump. The electrical work can be perfect and the post still snaps. Match the cart by make, model, year, and…
