36-volt Trojan golf cart batteries deliver extended runtime, reliable power output, and deep-cycle durability for electric vehicles. Designed with thick plates and advanced lead-actimony, they withstand frequent discharges and recharge efficiently. Ideal for hilly terrains or heavy loads, these batteries optimize cart speed and torque while lasting 4-7 years with proper maintenance.

How Long Do 36V Trojan Batteries Last in Golf Carts?
With 1,200-1,500 charge cycles at 50% DoD, Trojan 36V batteries typically last 5-8 years. Factors reducing lifespan include improper watering (electrolyte levels), sulfation from undercharging, and excessive vibration. Users report 18-36 holes per charge depending on cart weight (800-1,200 lbs) and motor efficiency (3-5HP). Monthly equalization charging extends longevity by 22% according to Trojan’s field tests.
48V 160Ah Lithium Golf Cart Battery
Battery lifespan varies significantly based on usage patterns. Carts used daily on mountainous courses may experience 20% faster capacity degradation compared to flat-terrain usage. Trojan’s Cycle Guard technology in newer models adds sacrificial plates that absorb corrosion, extending deep-cycle performance by 300+ cycles. For optimal results, avoid discharging below 48.6V and implement a weekly voltage check routine using digital multimeters. Below is a comparison of popular models:
| Model | Cycle Life | Weight | Ideal Use Case |
|---|---|---|---|
| T-605 | 1,200 cycles | 63 lbs | Moderate terrain |
| T-875 | 1,500 cycles | 68 lbs | Steep hills |
| T-1275 | 1,800 cycles | 72 lbs | Commercial fleets |
Which Maintenance Practices Maximize Trojan Battery Lifespan?
Weekly electrolyte checks (maintain 1/2″ above plates), terminal cleaning with baking soda paste, and torqueing connections to 95-105 in-lbs prevent power loss. Trojan recommends hydrometer testing every 60 days (1.277 specific gravity ideal) and avoiding discharges below 48.6V (36V system). Post-round partial recharges minimize sulfation – never store below 80% charge. Use only distilled water; contaminants reduce capacity by 15-30%.
Advanced maintenance includes using infrared thermometers to identify hot spots during charging, which may indicate failing cells. Implement a quarterly equalization charge at 2.58V per cell for 4 hours to balance cell voltages. For batteries in storage, maintain a float charge of 2.25V per cell and disconnect all accessories. Below is a maintenance frequency guide:
| Task | Frequency | Tools Needed |
|---|---|---|
| Electrolyte check | Weekly | Distilled water, funnel |
| Terminal cleaning | Monthly | Baking soda, wire brush |
| Hydrometer test | Every 60 days | Temperature-corrected hydrometer |
“Trojan’s 36V golf cart batteries outperform competitors through adaptive grid alloys that adjust to discharge patterns. Our recent tests show their Alpha+ series maintains 89% capacity after 800 cycles versus 74% in standard models. For extreme climates, we recommend the HydroLink watering system – it reduces maintenance time by 65% while preventing over/under-watering damage.”

News
Trojan Smart Carbonâ„¢ 2.0 Technology
In 2025, Trojan introduced an enhanced version of their carbon additive tech to boost charging efficiency and extend battery life in partial state-of-charge conditions—ideal for stop-and-go use like golf carts.
Integrated IoT Battery Monitoring
The newest 36V setups come with Bluetooth-connected battery monitors, allowing users to track voltage, temperature, and charge cycles via a smartphone app in real time.
Maintenance-Free AGM Upgrades
While flooded lead-acid batteries are still available, Trojan expanded its 36V AGM line with zero-maintenance models, reducing downtime and water-checking needs.
FAQs
- How often should I water Trojan golf cart batteries?
- Check electrolyte levels every 15-30 charging cycles. Add distilled water after charging (never before) until plates are covered by 1/4″. In hot climates, watering frequency increases by 40%.
- Can I mix old and new Trojan batteries?
- Never mix batteries with >6 months age difference. Mismatched cells reduce pack efficiency by 37% and risk reverse charging. Always replace entire 36V sets (6x6V or 4x8V).
- What charger voltage suits 36V Trojan systems?
- Use smart chargers with 36V/42V-45V output (2.35-2.45V per cell). Trojan recommends 10%-20% of Ah capacity as charging amps (e.g., 20A for 200Ah bank). Avoid chargers without temperature compensation.
