The lifespan of lead-acid batteries in golf carts typically depends on several factors, but here are the general expectations:
🔋 Typical Lifespan:
-
Flooded Lead-Acid Batteries (FLA):
👉 4 to 6 years under regular use and good maintenance -
Sealed Lead-Acid (AGM or Gel):
👉 3 to 5 years, generally lower than FLA due to different chemistry and charging sensitivity
⏱️ Key Factors That Affect Battery Lifespan:
-
Usage Patterns
-
Frequent deep discharges reduce battery life
-
Occasional use with full recharges extends life
-
-
Charging Habits
-
Consistently recharging after use and avoiding overcharging prolongs life
-
Leaving batteries uncharged or storing them dead can permanently damage cells
-
-
Maintenance (for FLA)
-
Regular water top-offs and clean terminals are critical
-
Poor maintenance can shorten life to 2–3 years
-
-
Climate Conditions
-
Extreme heat accelerates degradation
-
Freezing temperatures can cause permanent damage if batteries are not fully charged
-
-
Charger Quality
-
A smart charger that prevents overcharging and sulfation will significantly improve lifespan
-
🧰 Tips to Maximize Battery Life:
-
Charge after every use, not just when drained
-
Avoid full discharges—keep above 50% when possible
-
Clean terminals monthly
-
Use distilled water only for FLA batteries
-
Store batteries fully charged in cool, dry environments
If you're outfitting a fleet or evaluating long-term cost of ownership, lithium batteries—while more expensive—offer up to 10 years of life and require far less maintenance. Want a breakdown comparison between lead-acid vs. lithium for golf carts?
