Battery Brouhaha: Swap One or Go All-In for Your Golf Cart?

When it comes to your trusty golf cart, the battery is the unsung hero, providing the juice to keep you cruising along smoothly, whether you're on the greens, camping, or exploring trails.

Understanding Your Golf Cart Battery

Your electric golf cart runs on a pack of batteries - usually 4, 6, or 8 of them - depending on whether it's a 36-volt or 48-volt system. Keeping the right type and number of volts is crucial. Not enough power can turn your smooth ride into a sluggish struggle.

The Big Question: One Battery or All?

One of the top questions we get at SCV Carts is, “Should I replace just one bad battery or all of them at once?” It’s a debate that’s been going on as long as golf carts have been around, with some folks trying to save money and others advocating for a full swap.

Why Replacing Just One Battery Isn’t the Best Idea

Sure, replacing a single battery sounds like a quick fix, but it can lead to a host of problems. Here’s why:

  1. Poor Battery Life: Mixing old and new batteries can mess with charging efficiency and overall lifespan. The cart's charger looks at the total voltage, not individual batteries, so older cells can drag down the performance of new ones.

  2. Battery Power Imbalance: New batteries work more efficiently, but older ones might struggle, causing an imbalance that leads to slower acceleration and less speed.

  3. Longer Charging Times: Charging mixed batteries takes longer because the charger keeps going until the oldest battery reaches capacity.

So, What’s the Best Move?

Replace all the batteries at once. It might seem costly upfront, but it saves you from future headaches and extra expenses. Plus, it keeps your golf cart running smoothly.

Exceptions to the Rule

If you've already replaced all the batteries and still face issues, a voltage test can help pinpoint the problem. In such rare cases, replacing just the faulty batteries might be okay.

When to Replace Your Golf Cart Batteries

Wondering when it's time for new batteries? Here are some signs:

  1. Shorter Battery Life: If your cart struggles more often or the batteries aren’t holding a charge, it's a red flag.

  2. Longer Charging Times: If charging takes significantly longer than usual, it’s probably time for a replacement.

  3. Acid Leaks: If you see leakage around the battery pack, it’s a clear sign to swap them out.

  4. Decreased Acceleration and Power: If your cart's responsiveness is lagging, new batteries could solve the problem.

How Long Will New Batteries Last?

The lifespan of golf cart batteries varies but typically lasts 3 to 5 years, depending on the type and brand. Sealed batteries require less maintenance than flooded ones but may cost more upfront.

Cost of Replacing Golf Cart Batteries

Golf cart batteries aren’t cheap. Depending on your cart and battery type, replacing them can cost around $1,500 or more. It’s a significant investment, but necessary for keeping your cart in top shape.

Invest in a Quality Charger

Don’t skimp on the charger. A good charger extends battery life and ensures optimal performance, making your investment in new batteries worthwhile.


Replacing all your golf cart batteries at once might seem like a hefty expense, but it’s the best way to ensure longevity and performance. For the right batteries and chargers, visit SCV Carts, where we help keep your ride smooth and hassle-free.
