  • No water topping required
  • No acid leakage or corrosion
  • Can be installed in any orientation
  • Minimal self-discharge (3% vs 15% per month)

Installation & Compatibility

Voltage Compatibility:

  • 13.2V nominal is compatible with 12V systems
  • Voltage range: 10.0V (empty) to 14.6V (full)
  • Most 12V devices accept 10-15V input range
  • Verify your device specifications before replacing

Physical Dimensions:

  • Size: 27mm × 53mm × 134mm
  • Compact design fits most WP2.3-12 battery compartments
  • Lighter weight may require securing to prevent movement

Charging Requirements:

  • Important: Use LiFePO4-compatible charger (14.6V)
  • Do NOT use standard lead-acid chargers (may overcharge)
  • Recommended charge current: 0.5C (1.7A) or less
  • Built-in BMS protects against overcharge/over-discharge

Safety Information

Charging: Use only LiFePO4-compatible chargers (14.6V). Do not use lead-acid chargers.

Storage: Store at 40-60% charge (12.8-13.2V) in cool, dry place.

Operation: Do not short-circuit, puncture, crush, or disassemble the battery.

Temperature: Charge: 0-45°C, Discharge: -20-60°C, Storage: -20-35°C.

Disposal: Dispose according to local regulations. LiFePO4 is non-toxic but should be recycled.

BMS Protection: Built-in Battery Management System protects against overcharge, over-discharge, overcurrent, and short circuit.
