What Makes Trojan T-105 Golf Cart Batteries a Superior Choice?
Trojan T-105 golf cart batteries are flooded lead-acid batteries renowned for their deep-cycle performance, durability, and cost-effectiveness. Designed for electric vehicles, they deliver 225Ah at 6V, with thick plates for extended discharge cycles. Ideal for golf carts, solar storage, and industrial applications, they require regular maintenance but outperform competitors in lifespan (5-7 years) under proper care.

What Are the Key Specifications of Trojan T-105 Batteries?
The Trojan T-105 operates at 6V with 225Ah capacity, weighing 62 lbs. Key specs include: 20-hour rate (225Ah), 100-hour rate (255Ah), 6V nominal voltage, and 1,265+ cycles at 50% discharge. Terminal type: SAE, dimensions: 10.3″ L x 7.1″ W x 10.9″ H. Electrolyte density should maintain 1.277 specific gravity after full charge for optimal performance.
These specifications make the T-105 particularly suitable for applications requiring sustained energy output. The 1,265+ cycle rating at 50% depth of discharge (DoD) translates to nearly 3.5 years of daily use in golf carts before capacity drops below 80%. Compared to standard automotive batteries, the T-105’s thick lead plates (0.157″ vs. typical 0.09″) provide 40% greater active material surface area, enabling deeper discharges without sulfation. When configuring battery banks, users should note the 6V design requires series wiring – four units create a 24V system with 225Ah capacity, while eight units form a 48V array. The table below compares key parameters with similar deep-cycle batteries:

| Parameter | T-105 | US Battery 2200XC | Crown CR-235 |
|---|---|---|---|
| Cycle Life (50% DoD) | 1,265 | 1,100 | 1,150 |
| Weight (lbs) | 62 | 58 | 63 |
| Reserve Capacity (min) | 447 | 415 | 430 |
How to Properly Maintain Trojan T-105 Batteries for Maximum Lifespan?
Maintain T-105s by: 1) Watering with distilled water post-charge (never let plates expose), 2) Equalizing monthly (15.5V for 2-8 hours), 3) Cleaning terminals with baking soda solution, 4) Storing at full charge in cool environments. Avoid discharging below 50% capacity. Proper maintenance extends life to 7+ years versus 3-4 years with neglect.
Effective maintenance requires understanding the battery’s water consumption patterns. A typical T-105 in daily use consumes 0.5-1 ounce of water per cell weekly. Users should check levels every 15 charging cycles, maintaining fluid 1/8″ below fill wells. During equalization, monitor specific gravity until all cells stabilize between 1.265-1.299. Temperature significantly impacts maintenance needs – for every 15°F above 77°F, water consumption doubles. Implement these seasonal maintenance priorities:
- Spring: Complete capacity test after winter storage
- Summer: Increase watering frequency by 30%
- Fall: Apply anti-corrosion coating to terminals
- Winter: Maintain charge above 75% to prevent freezing
“Trojan T-105s thrive when paired with smart charging systems. We recommend temperature-compensated chargers adjusting voltage ±0.03V/°F from 77°F baseline. For golf carts, implement a 10% oversize rule – if your cart draws 100Ah daily, install 110Ah capacity. Always rotate battery positions in banks every 6 months to equalize wear from terminal proximity.”

FAQ: Trojan T-105 Golf Cart Batteries
- How many Trojan T-105 batteries do I need for a 48V golf cart?
- Eight 6V T-105 batteries wired in series (8×6V=48V). This creates a 225Ah bank. For extended range, create two parallel strings of eight for 450Ah total.
- Can I mix Trojan T-105 with older batteries?
- No. Mixing new and old batteries causes imbalance, reducing performance by 30-40%. Always replace entire banks. Trojan warranties void if mixed with non-Trojan batteries.
- What charger voltage suits Trojan T-105?
- Use a 6V charger with 7.35V absorption stage (25°C). Temperature-adjusted charging critical: reduce voltage by 0.03V/°F above 77°F, increase below. Bulk charge at 10-13% of Ah rating (22.5A max for T-105).
