Replacing all batteries in a golf cart typically costs between $600 and $2,500, depending on battery type (lead-acid vs. lithium-ion), voltage system (36V, 48V, or 72V), and brand. For example, a 48V system using six 8V lead-acid batteries costs $800–$1,800, while lithium-ion equivalents range from $2,000–$4,000. Labor adds $100–$300 if professionally installed.

What factors affect golf cart battery replacement costs?
Battery chemistry and voltage configuration dominate pricing. Lead-acid batteries cost $100–$300 per unit but require frequent replacements, while lithium-ion packs last 3x longer but cost $500+ per battery. A 72V system needing eight 9V batteries will exceed 48V setups in both capacity and price.
Golf carts commonly use 6V, 8V, or 12V batteries wired in series. A 48V system with six 8V lead-acid batteries (e.g., Trojan T-875) costs $1,200–$1,800 for the set. Lithium options like Redway’s 48V 100Ah LiFePO4 pack streamline installation with 50% weight reduction but start at $2,500. Pro Tip: Always replace all batteries simultaneously—mixing old and new units accelerates degradation. Consider cycle life: a $2,000 lithium pack lasting 2,000 cycles may be cheaper long-term than $1,500 lead-acid needing replacement every 500 cycles.
How do lead-acid and lithium-ion batteries compare for golf carts?
Lead-acid offers lower upfront costs but higher maintenance, while lithium-ion provides longer lifespan and faster charging. A 48V lead-acid pack lasts 4–6 years with proper care, whereas lithium-ion exceeds 10 years with minimal upkeep.
For a typical 48V golf cart, six 8V lead-acid batteries weigh ~360 lbs versus 150 lbs for lithium. Lithium’s 95% depth of discharge (vs. 50% for lead-acid) effectively doubles usable capacity. Charging time drops from 8 hours to 3–4 hours with lithium. However, lithium’s 2–3x higher initial cost deters budget-conscious buyers. Pro Tip: Calculate cost per cycle—lithium’s $0.15/cycle often beats lead-acid’s $0.30/cycle over time. Real-world example: A country club reduced annual battery costs by 60% after switching to lithium, despite higher upfront investment.
| Factor | Lead-Acid | Lithium-Ion |
|---|---|---|
| Cost (48V system) | $1,200–$1,800 | $2,500–$4,000 |
| Lifespan | 4–6 years | 10+ years |
| Weight | 360 lbs | 150 lbs |

FAQs
Yes, but verify controller compatibility first. Lithium batteries require specific voltage cutoffs—most 48V lead-acid systems actually peak at 58V, while lithium stays at 51V. Upgrade kits with BMS and adapters simplify transitions.
How often should golf cart batteries be replaced?
Lead-acid: Every 4–6 years with weekly use. Lithium-ion: 10–15 years. Always monitor capacity loss—if runtime drops below 60% of original, consider replacement.
