Increase Golf Cart Battery Life
1. Always Use Distilled Water
Battery maintenance is best done in a well-ventilated area on a plain and level surface. After removing the battery cells’ plastic caps, top off each cell’s reservoirs with distilled water. Never use plain or tap water. Also, never allow the cell’s fluid level to dip below its plates. In addition, never let the level of water in the battery be too high. As in, it should never be touching the plastic lip that goes down into the battery from the plastic cap. Just enough to make the batteries submerged is perfect. Too much can lead to acid overflow on to the top of the batteries and potentially damaging the garage floor below.
Attach the battery to a 3-phase charger, ensuring that the charger’s positive lead is attached to the battery’s red or positive pole and negative lead is joined with the negative pole. It’s also prudent to charge the battery after every time the golf cart is used.
3. Trickle Charge the Battery
If you’re going to store your battery for a long time, use a trickle charger to keep charging it while it’s being stored. Using a solar charger also works and prolongs the battery’s life. For a good trickle charger, we recommend a Battery MINDer produced by VDC Electronics.
4. Prevent Corrosion
Corrosion of the battery’s connections and posts is a major factor in shortening its life. That’s why you need to ensure that the battery is never discharged for more than seventy percent of its rated reserve capacity. This is because the longer it takes to recharge, the more it creates heat and destroys itself gradually by eroding its plates.
5. Use Anti-Corrosion Lubricants
The acid in a golf cart battery is one of the main agents for corroding its internal parts. In order to prevent this, coat its wire lugs, terminals, nuts, and bolts with any quality non-hardening sealant. A thin layer of pure Vaseline or petroleum jelly on the battery’s terminals also provides extra protection. Finally, sealing any exposed wires at the terminal lugs with submersible rubber tape also extends the battery life. These products can typically be found at your local auto parts store.
