Set of 6 US1800XC2 6V 208Ah Deep Cycle Battery
The US1800XC2 is a six-volt deep cycle battery from U.S. Battery designed for GC2 group size and 208Ah capacity. This Flooded Lead Acid option is widely used in golf carts, solar arrays, and marine systems. Its performance is well-suited for steady discharge over long durations, with a traditional flooded cell design that benefits from periodic maintenance and proper electrolyte management. Applications include RVs, solar-powered cabins, and backup power banks. When paired with an appropriately matched bank, it supports reliable morning starts and ongoing auxiliary power without frequent recharging.
US2200 XC2 6V 232Ah (4 Pack)
This four-pack of US2200 XC2 batteries offers 6V units at 232Ah each, making it a strong choice for larger 6V battery banks or replacement sets in RVs, solar arrays, and marine systems. The GC2 group size remains standard for many golf cart and solar installations. These flooded lead-acid cells benefit from routine watering and equalization charges to maximize lifespan. They are known for robust cycling performance in daylight-powered systems and provide ample reserve capacity for nighttime loads or extended cloudy periods.
Set of 4 US1800XC2 6V 208Ah
This set of four US 1800XC2 batteries provides a compact 24V bank when configured in series, or a larger capacity in parallel arrangements for extended runtime. With 208Ah per cell, users can support mid-to-large load profiles in RVs, off-grid cabins, or backup systems. As Flooded Lead Acid batteries, proper ventilation and regular maintenance are necessary. Cross-compatibility with other GC2-size batteries ensures flexible system design and replacement options without major rewiring.
Set of 8 US1800XC2 6V 208Ah
Eight six-volt, 208Ah batteries create a substantial energy reservoir for large solar arrays, off-grid homes, or high-demand RV setups. The GC2 format ensures broad compatibility with common battery racks and golf-cart configurations. Flooded lead-acid chemistry requires routine electrolyte checks, watering, and periodic equalization. When configured correctly, this pack can deliver reliable daily power and extended run times during periods of reduced solar input, though maintenance intensity is higher than AGM alternatives.
US2200 XC2 6V 232Ah (Single Reference)
The 6V, 232Ah US2200XC2 battery is a strong single-unit option within GC2 group sizing. This model is commonly used as part of a larger battery bank for solar energy storage or golf-cart power systems. Flooded lead-acid chemistry makes it suitable for deep cycling with regular maintenance. Its 232Ah capacity supports robust energy delivery and the ability to sustain higher discharge rates in shorter periods, depending on system design. This unit can be a reliable building block in a modular battery setup.
Buying Guide: Key Purchase Considerations
- Battery chemistry: Flooded lead-acid vs AGM. Flooded cells generally offer lower upfront cost and easier recycling but require ventilation, watering, and incident-free handling. AGM variants deliver maintenance-free operation and better resistance to spills, but at a higher price per Ah.
- Capacity and bank design: Match per-cell Ah ratings (208Ah vs 232Ah) to your total bank needs. Plan series connections for voltage (6V per cell) and parallel connections to increase Ah. Ensure the overall bank voltage aligns with your inverter or charge controller specs.
- Cycle life and depth of discharge: Deeper discharges shorten cycle life. Evaluate recommended DOD (depth of discharge) for your application to balance usable capacity and lifespan.
- Size and fit: GC2 group size is standard; verify battery rack clearance, terminal layout, and compatibility with existing mounting hardware before purchasing.
- Maintenance requirements: Flooded batteries require regular water top-ups and occasional equalization. AGM options minimize maintenance but may reduce total energy density per dollar.
- Installation considerations: Adequate ventilation for flooded batteries; secure mounting to prevent movement; corrosion protection on terminals; proper cabling and fusing to handle the expected current.
- Replacement strategy: If replacing a bank, consider consistent chemistry and capacity to minimize imbalances and ensure even charging across all cells.
