One other option would be to connect an external battery pack 9-12V, if the player has a DC connector (or to add a connector if it does not). I''d be careful about starting to mod the player too much. You''ll spend a lot of effort for a fragile solution and two weeks later the laser of the player craps out and you''ll have to do it all over again.

6 Frequently Asked Questions about “Replace only one battery pack”

Should a battery pack be replaced?

If a relatively new pack has only one defective cell and a replacement is located, exchanging the affected cell makes sense. With an aged battery, however, it's best to replace all cells. Mixing new with old causes a cell mismatch that has a short life. In a well-matched battery pack all cells have similar capacities.

Can a battery shop reuse a failed battery pack?

A battery shop may salvage good cells from a failed pack for reuse but the recovered cell should be checked for capacity, internal resistance and self-discharge – the three key health indicators of a battery.

Should you replace a single faulty battery?

If only one battery in a golf cart circuit is faulty, getting a second opinion from a qualified, expert technician is recommended. Replacing just one battery can lead to charging issues, poor battery life, and battery imbalance.

How do you charge a Li-ion battery without a protection circuit?

Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit. Include a temperature sensor that disrupts the current should the pack get hot. Apply a slow charge to a repaired pack to bring all cells to parity.

Can I replace just one battery on a golf cart?

It is generally recommended to replace all of the batteries at the same time. However, in this case, replacing only one or two would be acceptable. If you have replaced all of the batteries and find it is only one that is causing issues, replace that battery. (When You Should Replace Your Golf Cart Batteries?)

When should you replace a battery in a car?

When a single battery in a golf cart goes bad and needs replacing, it is recommended to change out all of the batteries. This may seem daunting, but it can save money in the long run.
