How Cold Effects Batteries

How Cold Affects Batteries

Winter has arrived and many don’t use their golf carts as often or at all during this time. It is important to remember that all deep-cycle lead acid batteries will self-discharge when not in use for an extended period of time. 

Most people think that when the charger is plugged into the cart, it keeps the batteries charged. This is not true. Most chargers automatically turn off when the batteries are fully charged but don’t turn back on when the batteries start to discharge. 

It is important that the batteries be re-charged at least once every 30 days during this period. This can be done by simply unplugging the charger cord from the cart and plugging it back in. This turns the charger back on and it goes through a charging cycle. 

For those that store their carts for more than a couple of months. We recommend having a discharge test done. You can call us to setup an appointment. 

Temperature also effects charge and discharge rates. A cold battery will charge and self-discharge slower than a warm battery, but will also exhibit lower capacity. The cold temperature increases the resistance in the battery’s chemistry and causes a reduction in battery capacity. A general rule of thumb for capacity is for every 15-20 degrees below 80 °F, the battery loses 10% of its capacity.
