How long do Trojan 48V golf cart batteries last?
Trojan 48V lithium-ion golf cart batteries, such as the TR GC2-48-G model, typically last 2–3 times longer than traditional lead-acid batteries, translating to a lifespan of 8–12 years under normal use. Designed for high performance, these batteries feature LiFePO4 chemistry and advanced BMS protection, ensuring durability even in demanding conditions. Pro Tip: Avoid deep discharges below 20% capacity to maximize cycle life—regular partial charges (e.g., after 18 holes) reduce stress on cells.

What factors influence Trojan 48V battery lifespan?
Charge cycles, depth of discharge (DoD), and temperature critically impact longevity. A Trojan LiFePO4 battery rated for 3,000 cycles at 80% DoD outperforms lead-acid equivalents by 300%.
Practically speaking, these batteries thrive in moderate climates (15–25°C). Extreme heat accelerates degradation—for every 10°C above 25°C, lifespan decreases by ~15%. Conversely, cold reduces capacity temporarily but doesn’t damage cells long-term. A real-world example: A golf cart used daily in Arizona (35°C average) may see 6–8 years of service versus 10+ years in milder regions. Pro Tip: Store carts indoors during heatwaves and use thermal-insulated battery boxes.
How does charging affect Trojan 48V battery life?
Proper charging preserves capacity—fast 4-hour charging with compatible chargers minimizes cell strain. Trojan’s BMS ensures balanced charging up to 54.6V (3.65V/cell).
Beyond voltage limits, partial charging (20–80% range) extends cycle life. For instance, charging after 18 holes (≈50% discharge) instead of full depletion adds 40% more cycles. Why? Lithium-ion cells experience less stress at mid-state charges. However, perform full charges monthly to recalibrate the BMS’s state-of-charge readings. A golf course fleet manager reported 11% longer battery life after implementing 80% charge limits during peak season.
| Charging Practice | Cycle Life | Annual Degradation |
|---|---|---|
| Full (100%) | 3,000 cycles | 8% |
| Partial (80%) | 4,200 cycles | 5% |

FAQs
Yes—they share similar dimensions and voltage profiles. However, update charger settings to lithium-specific parameters to avoid under/overcharging.
Do Trojan lithium batteries require watering?
No. Unlike lead-acid, they’re maintenance-free—no water refills or terminal cleaning needed. Simply keep them clean and dry.
