Why Everyone Searches for “T-105”

The T-105 is one of the most recognized deep cycle batteries ever made. Six of these wired in series give you a 36-volt system — the classic setup for older golf carts — while eight deliver a full 48-volt bank for newer Club Car, EZ-GO, and Yamaha models. The Trojan T-105 became the standard because it pairs 225Ah of deep-cycle capacity with a GC2 case that fits nearly every 6-volt bay on the market. Whether you're doing a full cart refit, building a solar bank, or powering an RV house system, this is the model number other 6V batteries are measured against.

What the T-105 Brings to the Table

Why the T-105 has been the reference standard for 6V deep cycle batteries for decades — and what to look for when comparing it against alternatives

225 Ah across 3 Cells

Each T-105 packs three 2-volt cells into a single GC2 case, delivering 225Ah at the 20-hour rate and approximately 1.50 kWh of stored energy. That capacity is the benchmark for 6V deep-cycle batteries used in golf carts, solar banks, and industrial equipment.

Flooded or AGM — Two Paths, One Footprint

The traditional T-105 is a serviceable flooded battery — proven, cost-effective, and easy to source parts for. The T105-AES uses absorbed glass mat technology for a fully sealed design that eliminates watering entirely. Both share the same GC2 dimensions, so the choice comes down to maintenance preference and installation environment.

Deep Discharge, Not Shallow Starts

Unlike starter batteries that deliver short high-current bursts, the T-105 is engineered for sustained draw and repeated deep cycling. Trojan's Alpha Plus paste with T2 Technology and Maxguard advanced separators are designed to resist degradation over hundreds of charge-discharge cycles in real working conditions.

Simplified Maintenance with HydroLink

Flooded batteries need regular watering, but it does not have to be tedious. The T-105 supports Trojan's HydroLink single-point watering system, which fills all three cells through one quick-connect fitting. For fleet operators managing dozens of batteries, that difference adds up fast.

447 Minutes at 25 Amps

The T-105 delivers 447 minutes of runtime at 25 amps and 115 minutes at 75 amps. That sustained draw performance is why it remains a top choice for equipment that depends on steady power over extended periods — from golf carts to floor scrubbers.
