Faster Power Draining
Once it does get fully charged, you should also observe how fast the battery drains. A typical golf cart runs an average of 7 miles for every single charge. If you notice that your golf cart isn’t covering the same mileage as it used to, then this could mean that the batteries are no longer charging as well as they should, even if they reach full capacity.
Bulging or Leaking Unit
This is one of the most obvious and definitive signs you need to replace your batteries. Acid leakage is not only a sure sign of battery deterioration, but it can also become dangerous. Battery acid is known to contaminate soil, which is certainly bad for the golf course and can also burn skin upon contact.
