Why Golf Cart Batteries Die

Before we dive into how to revive a dead golf cart battery, let’s first understand why they die. There are several factors that contribute to a golf cart battery’s lifespan, including overcharging, undercharging, and sulfation. Sulfation occurs when lead sulfate builds up on the battery’s lead plates, reducing its ability to hold a charge.

Overcharging occurs when the battery is left on the charger for too long or is charged with too much voltage. This can lead to the battery overheating and damaging its internal components.

Undercharging is another common reason for golf cart battery failure. If the battery is not charged enough, it will not be able to deliver the necessary power to the golf cart.

Sulfation is a natural process that occurs over time as the battery is used. As lead sulfate builds up on the battery’s plates, it reduces the battery’s ability to hold a charge.

Check the Voltage

Before attempting to revive a dead golf cart battery, you need to first check the battery voltage. This will give you an idea of how much charge is left in the battery and whether it is worth trying to revive it. Use a voltmeter to test the voltage of the battery. A fully charged 12-volt battery should read between 12.6 to 12.8 volts. If the battery voltage is below 11 volts, it is likely that the battery is completely dead and cannot be revived.

If the battery voltage is between 11 and 12 volts, it is possible to revive the battery by following the steps below. However, if the battery voltage is above 12 volts, the battery may be overcharged and could potentially cause damage to the golf cart or other electrical components. In this case, it is recommended that you seek the help of a professional to safely discharge the battery.

It is important to note that if the battery voltage is low, but not dead, it may still be possible to charge the battery and use it for a short period of time. However, it is not recommended to rely on a battery that has low voltage as it may cause problems down the line and potentially damage your golf cart.
