Trojan T105 golf cart batteries are renowned for their durability, deep-cycle performance, and reliability in electric vehicles. These 6V flooded lead-acid batteries provide consistent power output, long cycle life (1,200+ cycles at 50% discharge), and exceptional value for golf carts, industrial equipment, and renewable energy systems. Their rugged construction and proven design make them a leader in the market.

How Do Trojan T105 Batteries Compare to Other Golf Cart Batteries?
Trojan T105 outperforms competitors like US Battery and Crown through superior plate thickness (0.09″ positive plates) and higher lead purity. Unlike AGM or lithium alternatives, these flooded batteries offer 225-250Ah capacity at 20-hour rate, supporting longer runtime. Their 10-12 year design life exceeds most 6V golf cart batteries when properly maintained.
What Are the Key Specifications of Trojan T105 Batteries?
The T105 delivers 225Ah at 6V with 1,265 minutes of reserve capacity. Weighing 62 lbs, it features tubular positive plates and a high-density paste formulation. Operating temperature range spans -40°F to 140°F. Requires regular watering (every 5-10 cycles) and equalization charging monthly. Nominal voltage: 6V, Dimensions: 10.3″ L x 7.1″ W x 10.9″ H.
Why Choose Flooded Lead-Acid Over AGM for Golf Carts?
Flooded batteries like T105 provide 30% more cycles than equivalent AGM models at similar price points. While requiring maintenance, they offer better heat dissipation and recoverability from deep discharges. AGM batteries (maintenance-free) cost 2-3x more and typically last 20% fewer cycles in golf cart applications.
How to Properly Maintain Trojan T105 Batteries?
Maintenance protocol: Check electrolyte weekly (keep plates submerged), use distilled water only. Clean terminals with baking soda solution monthly. Equalize monthly at 7.3-7.4V for 2-4 hours. Store at full charge in cool, dry locations. Avoid discharging below 50% (4.8V under load). Use only golf cart chargers with automatic shutoff (55-60V for 48V systems).
Advanced maintenance includes using a refractometer to measure specific gravity (1.277 at full charge) rather than relying solely on voltage readings. Install automatic watering systems for multi-battery installations to ensure consistent fluid levels. For winter storage, maintain batteries at 70% charge in frost-free environments to prevent freezing electrolyte. Professional servicing every 200 cycles helps identify early signs of sulfation or plate degradation.
| Maintenance Task | Frequency | Tools Required |
|---|---|---|
| Electrolyte Check | Weekly | Distilled water, funnel |
| Terminal Cleaning | Monthly | Baking soda, wire brush |
| Equalization Charge | Every 30 cycles | Smart charger |
What Environmental Factors Impact T105 Battery Lifespan?
Temperature extremes reduce lifespan – every 15°F above 77°F halves battery life. Vibration from rough terrain accelerates plate shedding. Humidity below 40% increases water loss. Install battery trays with vibration damping and maintain 1″ spacing between cells for optimal airflow in humid environments.
How Does Trojan’s Warranty Protect T105 Buyers?
Trojan offers 18-month free replacement (pro-rated after) against manufacturing defects. Warranty requires proper installation and maintenance documentation. Excludes sulfation from chronic undercharging. Claims must be filed through authorized dealers with original purchase proof. Average prorated refund: 60% of MSRP after first year.
Can Trojan T105 Batteries Work With Solar Systems?
Yes, when configured in series/parallel banks. For 12V systems: pair two T105s in series, then parallel sets for capacity. Requires compatible charge controller (40-60A MPPT recommended). Limit discharge depth to 50% for solar applications. Daily cycling reduces lifespan to 4-6 years vs 8-10 in golf carts. Use Hydrocaps to reduce water loss in off-grid setups.
Solar users should implement temperature-compensated charging to account for environmental variations. A 24V system using four T105 batteries (2 series pairs in parallel) provides optimal balance between voltage efficiency and capacity. Monitor individual battery voltages with a bank monitor to prevent reverse charging. In hybrid systems, combine with lithium batteries using a DC-DC converter to handle peak loads while preserving T105 cycle life.
| System Voltage | Battery Configuration | Total Capacity |
|---|---|---|
| 12V | 2S (2×6V in series) | 225Ah |
| 24V | 4S2P (4×6V series, 2 parallel) | 450Ah |
| 48V | 8S (8×6V in series) | 225Ah |
“Trojan T105 remains the workhorse of motive power batteries because of its balanced design. While newer technologies emerge, the T105’s 1,200+ cycle life at 50% DoD still outperforms most competitors in its class. Proper maintenance is key – we see 8-year-old T105s still performing in solar installations when watered and equalized religiously.”

Conclusion
The Trojan T105 sets the gold standard for golf cart batteries through unmatched durability and proven performance. While requiring regular maintenance, its deep-cycle capabilities and cost-effectiveness make it ideal for serious users. Implementing proper charging practices and environmental controls can extend service life beyond typical expectations.
