Why You Should Regularly Check the Charge of Your Golf Cart Lithium Battery During Long-Term Storage

Golf cart lithium batteries are known for their durability, long life, and low maintenance compared to lead-acid batteries. However, many owners overlook one important fact: if your golf cart will be unused for weeks or months, you should still check your battery’s charge level regularly. This simple habit can prevent damage, extend lifespan, and ensure your cart is always ready when you need it.

1. Lithium Batteries Still Lose Charge Over Time

Even when not in use, lithium batteries experience self-discharge—a slow loss of stored energy. While lithium’s self-discharge rate is much lower than lead-acid batteries, it’s not zero. Environmental conditions like temperature and humidity can also influence how quickly the charge drops.

2. Deep Discharge Can Damage the Battery
If the battery’s voltage falls too low, it can trigger the BMS (Battery Management System) to shut down the pack to protect it. In extreme cases, deep discharge can cause irreversible damage to the cells, reducing overall capacity and lifespan.
Tip: Most manufacturers recommend keeping the battery’s charge between 50% and 80% during storage.

3. Protecting Your Investment
Lithium golf cart batteries are a significant investment—often lasting 8–10 years when cared for properly. Neglecting periodic charge checks during long-term storage can shorten that lifespan, leading to premature replacement costs.

4. How Often Should You Check the Charge?
For most golf cart lithium batteries, checking the charge every 1–2 months is enough during storage. If you have a Bluetooth-enabled battery, monitoring is even easier—you can check voltage and charge level right from your phone.

5. Storage Best Practices
- Charge before storage: Bring the battery to around 80% charge.
- Disconnect accessories: Remove or disconnect devices that may draw power.
- Store in a cool, dry place: Avoid extreme heat or freezing temperatures.
- Use a smart charger: For long-term storage, Our chargers have a “maintenance mode” to keep the battery at an ideal level.

Conclusion
Your golf cart lithium battery is built for long service life, but proper care during downtime is essential. Regularly checking the charge during long-term storage is a small effort that pays off in longer lifespan, better performance, and peace of mind. Think of it as a health check-up for your battery—simple, quick, and worth it.
