A golf cart without a battery is like golf without a swing.
– nothing works without energy!And that's exactly why we want to take a closer look at the heart of every cart today: the battery. It sounds technical at first – and it is. But don't worry: we'll make it understandable, practical, and with a touch of humor.
Because one thing is certain: if you love your cart, you take care of it. And not just when it comes to tire pressure or brake checks, but especially when it comes to battery maintenance. Why? Because a little attention can prevent expensive damage. So, let's get started!
1. The classics: lead-acid batteries – solid but thirsty
They are, so to speak, the “oldies but goldies” among golf cart batteries: classic lead-acid batteries. Known for their low price and robust construction, they deliver reliable power – if treated properly.
Advantages:
- Inexpensive to purchase
- Proven technology
- Widely available
But beware: these batteries require maintenance. Checking the water level, charging regularly, and avoiding deep discharge are essential. If you neglect this, you will end up paying for it. Dry running or sulfation quickly lead to premature battery failure.
Our tip: If you use lead-acid batteries, you have to take care of them. Not only during the golf season, but also during the winter break. Otherwise, it will be expensive.
Why “How many years will my battery last?” is not a simple question.
A common question we receive:How long does a battery actually last?” The honest answer: it depends. This is because the service life of batteries is measured in charge cycles rather than years.
A charge cycle describes a complete discharge and recharge process. Depending on the type of battery, this can be between 300 (for simple lead-acid batteries) and over 2,000 cycles (for high-quality lithium batteries) when used properly.
But beware: how quickly these cycles are “used up” depends heavily on usage behavior, maintenance, depth of charge, and storage. For example, if you use your cart every day and only charge it halfway, you will use up cycles much faster – and thus shorten its service life.
Our tip: With the right care and charging practices, the service life can be significantly extended – regardless of the battery type. Even an expensive
The improved: AGM/AES batteries – low maintenance, but demanding
AGM (Absorbent Glass Mat) or AES (Advanced Energy Storage) batteries are the “next generation” of lead technology. The electrolyte is bound in glass fiber mats, which makes the battery leak-proof and virtually maintenance-free.
Advantages:
- No need to top up with water
- Lower self-discharge
- Longer service life with good care
But here too, care means not ignoring the battery. AGM batteries do not like deep discharge and reward regular full charges with a long service life. They are also slightly more sensitive to incorrect charging technology. So please use the right charger!
3. The future: Lithium batteries – lightweight, durable, powerful
When talking about battery revolutions, lithium batteries are impossible to ignore. They are the high-tech version for anyone who wants performance and convenience – and is willing to invest more to get it.
Advantages:
- Extremely lightweight (up to 50% lighter!)
- Very long service life
- Fast charging
No maintenance required: But of course, even lithium batteries are not indestructible. Incorrect storage, extreme temperatures, or unsuitable chargers can cause damage. They are also significantly more expensive to purchase – but if you do the math, you will quickly realize that the investment pays off over the years.
Our tip: Ideal for frequent drivers, frequent users, or anyone who simply wants “peace of mind” – in the best sense of the word.
Conclusion
No matter what type of battery you have, maintenance is essential!Whether lead-acid, AGM, or lithium, a battery is only as good as how it is treated.
This means:
- Regular recharging
- Proper storage during the off-season
- Keeping an eye on the charge status
- Using the right charger
Because even when the cart is “just standing around,” chemical processes continue to work inside. If you are careless here, you risk expensive replacement—and that is avoidable!
