Frequently Asked Questions
What is the difference between AGM and flooded lead-acid batteries for golf carts?
AGM (Absorbent Glass Mat) batteries are sealed, maintenance-free, and have lower internal resistance, allowing faster charging and better performance in cold weather. They are also vibration-resistant and spill-proof. Flooded lead-acid batteries are cheaper but require regular watering, are prone to corrosion, and can spill if tipped. For golf carts, AGM is generally preferred for convenience and durability, but flooded batteries can be a cost-effective option if maintenance is acceptable.
How many amp-hours (Ah) do I need for my golf cart?
Most golf carts use 100Ah to 120Ah batteries for a full round of 18 holes with moderate accessory use. If you have a heavy cart, hills, or run many accessories (lights, stereo), consider a higher Ah rating like 100Ah or more. Lower Ah (66Ah) may suffice for flat courses and minimal accessories but will require more frequent charging.
Can I use a regular car battery in my golf cart?
No, car batteries are designed for short bursts of high current (starting) and are not built for deep cycling. Using a car battery in a golf cart will lead to premature failure due to repeated deep discharges. Always use a deep cycle battery (or dual-purpose) designed to handle deep discharges without damage.
How long should a 12V deep cycle battery last in a golf cart?
With proper care, a quality AGM deep cycle battery can last 4-6 years, while flooded batteries typically last 3-5 years. Factors include depth of discharge, charging habits, temperature, and maintenance. Avoid discharging below 50% capacity to maximize lifespan.
What is reserve capacity and why does it matter?
Reserve capacity (RC) is the number of minutes a battery can deliver 25 amps at 80°F before voltage drops below 10.5 volts. A higher RC means longer runtime for accessories if the engine is off. For golf carts, an RC of 150-200 minutes is typical; more is better if you use lights or other electronics.
