Trojan golf cart batteries are lead-acid energy storage solutions widely used in golf carts for their proven durability and industry recognition. While not lithium-based, their flooded or AGM designs deliver 180–250 cycles at 50% depth of discharge (DoD), requiring regular water maintenance. Modern lithium alternatives like LiFePO4 now outperform them in cycle life (2,000+ cycles) and weight reduction but remain pricier upfront. Trojan’s reputation stems from consistent performance in moderate-use scenarios.
Why Trojan Golf Cart Batteries Are the Top Choice
How do Trojan batteries compare to lithium alternatives?
Trojan’s lead-acid batteries prioritize lower upfront costs but lag in energy density and maintenance needs. Lithium-ion counterparts offer 4x cycle life and 60% weight savings but cost 2-3x more initially.
Practically speaking, Trojan T-105 6V batteries deliver 225Ah (20hr rate) but weigh 62lbs each—a 48V system requires eight units totaling 496lbs. Comparatively, a 48V 100Ah LiFePO4 pack weighs 110lbs with equivalent usable energy. Pro Tip: Calculate total ownership costs—lithium often becomes cheaper after 3-5 years despite higher initial investment. For example, replacing Trojan batteries every 4 years versus lithium’s 10+ year lifespan significantly alters cost dynamics.
| Metric | Trojan T-105 | LiFePO4 48V |
|---|---|---|
| Cycle Life (80% DoD) | 1,200 | 3,500+ |
| Weight per kWh | 33 lbs | 14 lbs |
| Peak Efficiency | 80% | 98% |
What maintenance do Trojan golf cart batteries require?
Trojan’s flooded batteries demand monthly water refills and terminal cleaning to prevent sulfation. AGM versions reduce but don’t eliminate maintenance.
Beyond electrolyte levels, users must equalize charge every 60 days—a controlled overcharge restoring plate sulfates. Pro Tip: Use only distilled water; tap minerals accelerate corrosion. Imagine a golf cart used weekends: Without equalization, capacity drops 15% monthly. But what if you skip terminal cleaning? Copper sulfate buildup increases resistance, causing voltage drops under load.

FAQs
No—their 50% DoD limit suits intermittent use. Daily deep discharges below 50% capacity reduce lifespan by 40%.
Are Trojan AGM batteries worth the premium?
Partially: They eliminate watering but still require voltage checks. Lithium remains better for maintenance-averse users despite higher cost.
