How do I know when my lead-acid golf cart battery needs to be replaced?

Here are some signs that your golf cart battery may need to be replaced:

1. Reduced Range: If your golf cart isn’t going as far on a full charge as it used to, it may be a sign that the battery is losing capacity and needs replacement.

2. Slower Speed: If your golf cart is sluggish or doesn’t go as fast as it used to, the battery might not be providing enough power.

3. Frequent Charging: If you’re having to charge the battery more often, it could indicate that it’s not holding a charge as effectively.

4. Struggling on Hills: If your cart struggles to climb hills or even flat ground, it's a sign the battery is not providing enough power.

5. Corrosion or Leakage: Visible corrosion around the terminals or a battery leak can indicate damage to the battery and may mean it’s time for a replacement.

6. Battery Age: If your battery is older than 4-6 years (for lead-acid batteries), it might be nearing the end of its useful life, even if it doesn’t show obvious symptoms yet.

7. Battery Warning Light: If your cart has a battery indicator or warning light, and it’s flashing or turning red even after charging, it could indicate a problem with the battery.

8. Faster Discharge: If the battery drains very quickly after charging or doesn’t hold the charge as long, it’s likely time for a replacement.

If you notice any of these signs, it’s a good idea to have your battery tested or replaced before it completely fails.
