What Are Trojan T105 Batteries?
Trojan T105 batteries are 6V deep-cycle lead-acid batteries designed for heavy-duty applications like golf carts and industrial equipment. With a nominal capacity of 225–230Ah, they utilize advanced AGM/flooded-cell technology to deliver reliable power, extended cycle life (1,200+ cycles at 50% DOD), and vibration resistance. Typically configured in 6-unit series setups for 36V systems, they support golf cart brands like Club Car and EZGO. Proper watering and 3-stage charging (bulk/absorption/float) at 7.35–7.45V per cell optimize performance.
Which Golf Cart Batteries Work Best
What are the key specifications of Trojan T105 batteries?
Trojan T105 batteries operate at 6V nominal voltage with 225Ah capacity, achieving 1,290Wh energy storage per unit. Their deep-cycle design allows 80% depth-of-discharge (DOD), providing 550–600 cycles in golf cart applications. Weighing 29kg, they feature lead-calcium alloy grids and tubular positive plates for corrosion resistance. Pro Tip: Use hydrometers monthly—specific gravity should stay between 1.277 (full charge) and 1.155 (50% DOD).
Unlike starter batteries, T105s sustain prolonged discharges, making them ideal for golf carts requiring 5–6 hours of runtime. For example, a 36V setup (6x6V) powers mid-sized carts for 35–45 holes on flat terrain. However, steep hills increase amperage draw by 30%, necessitating larger battery banks. Always match chargers to voltage configurations—a mismatched 12V charger could permanently sulfate cells. Did you know Trojan’s Tempest algorithm adjusts charging voltages for ambient temperatures between -18°C to 50°C? This prevents overcharging in summer and undercharging in winter, extending service life by 20%.
What applications use Trojan T105 batteries?
Primarily deployed in electric golf carts, T105 batteries also power floor scrubbers, solar storage systems, and marine trolling motors. Their high cyclic stability suits applications requiring daily deep discharges. Flooded models dominate industrial use, while AGM variants serve vibration-prone environments like boats.
Beyond mobility applications, these batteries excel in off-grid setups. A 48V solar bank (8x6V) can store 18.4kWh, sufficient for a small cabin’s lights and refrigeration. Pro Tip: When using multiple strings, implement fuse blocks per string—parallel connections without protection risk thermal runaway. Transitional setups like hybrid golf carts with solar panels benefit from Trojan’s 10% overcharge tolerance, allowing direct panel connections through MPPT controllers. However, industrial forklifts often upgrade to higher-capacity T1275 models since T105s provide limited 2-hour runtime under 400A loads.
| Application | Voltage Configuration | Runtime |
|---|---|---|
| Golf Cart | 36V (6x6V) | 5–6 hours |
| Solar Storage | 48V (8x6V) | 18–24 hours |
How do T105 batteries compare to other Trojan models?
T105s occupy the mid-tier in Trojan’s lineup, outperforming T-605s (180Ah) but lagging behind T-125s (240Ah). Their balanced cost-to-capacity ratio makes them popular for recreational vehicles, though commercial users often prefer T-875s (8V/170Ah) for higher voltage density.
Compared to lithium alternatives, T105s have lower upfront costs ($1180 for six vs. $3200+ for LiFePO4 equivalents) but require more maintenance. However, in cold climates (-10°C), lead-acid models retain 80% capacity versus lithium’s 50–60%. For golf course operators, this translates to reliable winter performance despite reduced range. Transitional phrase: While lithium gains popularity, Trojan’s sealed T105-AGM variant bridges the gap with spill-proof design and 98% recharge efficiency. Still, always ventilate battery compartments—hydrogen emissions during charging demand 4 air changes per hour.
| Model | Voltage | Capacity |
|---|---|---|
| T-105 | 6V | 225Ah |
| T-125 | 6V | 240Ah |
| T-875 | 8V | 170Ah |
What maintenance do Trojan T105 batteries require?
Monthly electrolyte level checks are critical—distilled water should cover plates by 3–5mm. Post-charging equalization every 30 cycles (15.3V for 4 hours) prevents stratification. Terminals need anti-corrosion gel and torque checks (7–9Nm) quarterly.
Practically speaking, a neglected T105 loses 4% capacity monthly due to sulfation. For example, a golf cart left uncharged over winter might require $200 desulfation treatments. Pro Tip: Install automatic watering systems like HydroLink—they reduce maintenance time by 85% in fleet applications. Transitional phrase: Beyond fluid management, storage practices matter. At 50% charge, T105s withstand -20°C without freezing, but permanent capacity loss occurs below 1.8V/cell. Use maintenance chargers during off-seasons, ensuring voltage never drops below 6.32V (10.5V for 12V systems).
