Trojan lead-acid batteries are a traditional and widely used option for golf carts, offering reliable performance at a lower upfront cost. Known for their 6V/8V configurations and deep-cycle capabilities, models like the Trojan L16P-AC (6V, 420Ah) provide sufficient energy for moderate driving ranges. However, they require regular maintenance, including water refilling and terminal cleaning, and typically last 4–6 years with proper care. Compared to lithium alternatives, Trojan batteries are heavier (adding ~400 lbs to the cart) and slower to charge, but remain cost-effective for budget-conscious users.

How do Trojan batteries compare to lithium-ion options?
Trojan lead-acid batteries prioritize affordability and proven technology, while lithium-ion variants excel in weight reduction and lifespan. Key trade-offs include Trojan’s 50% lower upfront cost versus lithium’s 3× longer cycle life. Lithium also charges 70% faster and operates maintenance-free.
Trojan batteries use flooded lead-acid (FLA) or AGM designs, requiring monthly electrolyte checks and ventilation. For example, a 48V Trojan T-105 setup (8×6V) weighs 600+ lbs versus 150 lbs for a comparable lithium pack. Pro Tip: Use distilled water only for refilling Trojan batteries—tap water minerals accelerate plate corrosion. Transitionally, while lithium dominates modern upgrades, Trojan remains viable for occasional users prioritizing initial savings.
| Feature | Trojan FLA | Lithium |
|---|---|---|
| Cycle Life | 1,200 cycles | 3,000+ cycles |
| Weight per 48V | 600 lbs | 150 lbs |
| Charge Time | 8–10 hours | 2–4 hours |
What maintenance do Trojan golf cart batteries require?
Trojan batteries demand routine maintenance to prevent sulfation and capacity loss. Tasks include monthly water refills, terminal cleaning, and equalization charging every 30–60 days.
Flooded lead-acid cells lose water during charging, requiring distilled water top-offs to keep plates submerged. Neglecting this risks exposed plates sulfating, which can irreversibly cut capacity by 30%+. For instance, Trojan’s T-105 manual specifies maintaining electrolyte 1/8″ above plates. Pro Tip: Use a baking soda solution to clean corroded terminals—prevents voltage drops. Practically speaking, users in dusty environments should inspect terminals biweekly. Why does this matter? Poor connections force batteries to work harder, generating excess heat that shortens lifespan.

FAQs
Yes, but expect 18–24 month replacement cycles under heavy daily loads. Lithium lasts 5–8 years in similar conditions.
Are Trojan batteries compatible with all golf carts?
Most 36V/48V carts support Trojan’s 6V/8V configurations, but verify tray dimensions—some lithium conversions need adapters.
