Trojan T-105 6V Deep Cycle Battery (Set of 4)
Model: T-105, Voltage: 6, Capacity: 225Ah at 20 hours. BCI: GC2. This bundle is positioned for larger golf-cart or off-grid arrays that require steady, long-lasting power delivery. The GC2 format is widely compatible with standard 6V configurations, and the 225Ah rating supports extended runtimes in renewable energy and backup systems. Weight and dimensions align with common GC2 specs, aiding straightforward installation in existing racks.
Trojan T-105 GC2 6V 225Ah Battery (x2)
This is the 225Ah, 6-volt deep cycle battery in the GC2H golf-cart size. Suitable for RVs, cabins, and home energy systems, it supports multiple configurations from modest to large capability banks. Dimensions approximate 10.30 x 7.13 x 11.07 inches; weight around 62 pounds. The GC2 form factor is well-supported by standard rack systems and interconnects for 6V strings.
Trojan T-105 6V 225Ah Battery (GC2, Set of 12)
A higher-quantity option for larger applications or fleet installations. The T-105 uses the well-known GC2 configuration and provides 225Ah per unit, making it suitable for extended-run solar or backup systems. Includes robust construction for repeated cycling and a durability-focused design to resist vibration in mobile setups.
Trojan T-125 6V 240Ah GC2 Deep Cycle (x4)
With 240Ah per battery, the T-125 provides higher capacity in the same GC2 footprint. This makes it suitable for larger off-grid installations, longer solar days, or high-demand off-grid loads. The 6V configuration remains compatible with standard 6V wiring and 12V sub-stringing configurations when paired appropriately with balance and battery management considerations.
Trojan T-105 GC2 6V 225Ah (x6)
A sizeable bank configuration for demanding loads. Each unit offers 225Ah at 6V, with GC2H sizing for robust rack compatibility. This setup supports higher-capacity solar storage or backup systems requiring more parallel strings to meet load demands. The battery design emphasizes long cycle life and dependable performance under deep discharge conditions.
US2200 XC2 6V 232Ah (Pack of 4)
4-pack option from U.S. Battery, offering GC2 group size compatibility and 232Ah per battery. This configuration provides a solid substitute for Trojans in 6V bank builds, with a focus on robust construction and reliable cycle life for renewable energy storage, golf carts, and backup systems. The pack format simplifies installation in larger arrays and allows flexible balancing across strings.
Buying Guide: Key Purchase Considerations
- Capacity and runtime: Higher Ah per battery translates to longer runtimes between charges. Match Ah to your load profile and expected daily draw.
- Bank size and configuration: GC2 or GC2H sizing affects fit in standard racking. Plan the number of blocks to meet voltage and capacity targets.
- Cycle life and depth of discharge: Flooded lead-acid designs tolerate deep discharges but require careful maintenance, watering, and venting in some climates.
- Maintenance needs: Flooded cells require regular watering, terminal tightening, and equalization. Sealed alternatives may reduce maintenance but differ in performance.
- System compatibility: Ensure wiring, interconnects, battery management system (BMS or charger) compatibility with 6V or 12V strings and series/parallel configurations.
- Physical dimensions and weight: Verify rack space, mounting surface, and weight limits for safe installation, especially in mobile environments.
- Warranty and support: Consider manufacturer warranties and availability of replacement cells or troubleshooting resources for long-term reliability.
- Replacement options: Trojan and US Battery provide widely used GC2 formats, enabling straightforward substitution in existing systems.
