  • Voltage / Capacity: 6 Volt, 400Ah @ C20
  • BCI Group Size: L16
  • Reserve Capacity: ~950 minutes @ 25A
  • Chemistry: Sealed AGM (VRLA) – maintenance-free, spill-proof
  • Construction: Mil-Spec design, Coast Guard approved, DOT HazMat exempt
  • Self-discharge: ~2% per month at 77°F (significantly lower than flooded)
  • Use cases: Solar energy storage, RV/Marine house banks, off-grid, backup power

Charging Guidance (AGM)

  • Bulk/Absorb: 7.10 – 7.30 V (6V battery)
  • Float: 6.55 – 6.70 V
  • Use a high-quality charger/regulator with AGM profile; temperature compensation recommended.

FAQ

Q: Is this battery truly maintenance-free?
A: Yes. As a sealed AGM (VRLA), it never needs watering and is spill-proof. Use correct AGM charging voltages to maximize life.

Q: Can I use GPL-L-16 for solar off-grid?
A: Absolutely. Its deep-cycle design and large 400Ah capacity make it ideal for solar storage and inverter loads.

Q: How does it compare to flooded L16?
A: AGM offers lower self-discharge, faster charge acceptance, no watering, and better vibration resistance, at a higher upfront cost.

Q: What about cold-cranking amps?
A: This is a deep-cycle house battery. Starting ratings exist but aren’t the primary metric; design your system around Ah and reserve capacity.
