Battery Maintenance
Maintenance
You should always keep your golf cart batteries clean and check their fluid level every month. You can just pop off the tops and peek in to see the water levels. Make sure that the water is higher than the plates, but not too full.
“NEVER EVER USE TAP WATER!” Always use DI (De ionized Water) water or Distilled water.
You can also use a battery watering system to help with the process. You can also use a turkey baster to make sure you can get the right amount in each cell.
The hotter the temp, the quicker the set of batteries will discharge. The older the batteries, the more frequently you need to check your water levels.
Older batteries use more water.
Correctly watering your flooded lead-acid batteries is the most important battery maintenance tip. Water loss must be replaced to prevent battery plate damage.
Never allow the electrolyte level to fall below the plates. The worst thing you can do to electric golf cart batteries is to let them sit in a hot garage without ever charging them. Avoid running your golf cart on a low charge as this can be very hard on your batteries and can shorten their running range.
Charging
Batteries need to get fully charged between uses. Using your golf cart when your batteries aren’t fully charged leads to hard sulfation and can affect battery performance and the range of your batteries.
Make sure your batteries have enough time to complete a charge cycle before using your cart. If possible, charge your batteries every day and add water after the charge. Do not drive the vehicle until the battery dies; lead-acid batteries will not last as long if you completely discharge them. Rule of thumb is to never discharge below 50%.
It’s better to start charging a golf cart battery when there’s enough time to fully charge it before your next trip.
Safety Considerations
- Lead‑acid batteries vent off Hydrogen when charging. Hydrogen is a very flammable gas. Always Charge Lead Acid Batteries in a well ventilated area.
- Personal Protective Equipment (PPE)
- Chemical‑resistant gloves (nitrile or neoprene) to prevent acid burns.
- Splash‑rated goggles or a full face shield to protect against electrolyte spray.
- Long sleeves and acid‑resistant apron to reduce skin exposure.
- Non‑sparking tools to avoid ignition hazards.
