Felicity Solar G12V250AH 12V 3kWh Gel Battery features

  • 3 kWh of stored energy

    250 Ah at 12 V, rated at the 10-hour rate to 1.8 V per cell at 25 °C.

  • 3.8 mΩ internal resistance

    A low internal resistance limits the voltage sag under a heavy draw.

  • 2500 A maximum discharge current

    Headroom for the inrush a motor or inverter load pulls at start-up.

  • 75 A maximum charging current

    It sizes the charge controller or charger you pair with this battery.

  • Six cells in a 70.1 kg case

    One block of 522 × 260 × 220 mm, so plan the lift and the shelf for it.

  • Under 3% self-discharge per month

    Stored from -20 °C to 60 °C, with 20 °C to 30 °C the optimal band.

About the Felicity Solar G12V250AH 12V 3kWh Gel Battery

The Felicity Solar G12V250AH is a 12 V gel battery rated 250 Ah at the 10-hour rate to 1.8 V per cell at 25 °C, which is 3 kWh of nominal energy. Its internal resistance is 3.8 mΩ, it accepts up to 75 A of charging current, and it weighs 70.1 kg. Six cells sit in one case measuring 522 × 260 × 220 mm. Charge to a maximum of 14.6 V, hold cyclic service between 14.4 V and 14.6 V, float between 13.6 V and 13.8 V, and stop the discharge between 9.6 V and 10.5 V. The maximum discharge current is 2500 A. Charging is rated from 0 °C to 50 °C and discharging from -20 °C to 60 °C, with 20 °C to 30 °C the optimal band, and storage spans -20 °C to 60 °C. Self-discharge stays under 3% per month, so a shelved unit keeps its charge between jobs. We are an authorised Felicity Solar distributor, and the G12V250AH carries a warranty of 2 Years.

Frequently Asked Questions

How much energy does the G12V250AH store?

3 kWh. The G12V250AH is rated 250 Ah at 12 V, measured at the 10-hour rate to 1.8 V per cell at 25 °C, and its six cells sit in a single case.

What charging voltage and current does the G12V250AH need?

75 A is the maximum charging current and 14.6 V the maximum charging voltage. Hold cyclic service between 14.4 V and 14.6 V, float between 13.6 V and 13.8 V, and charge only between 0 °C and 50 °C.

How much does the G12V250AH weigh and how big is it?

70.1 kg, in a case measuring 522 mm wide, 260 mm high and 220 mm deep. Plan a two-person lift and a shelf rated for that mass.

What is the internal resistance and the peak discharge current?

3.8 mΩ internal resistance and a maximum discharge current of 2500 A. Discharging is rated from -20 °C to 60 °C, with 20 °C to 30 °C optimal and a cut-off between 9.6 V and 10.5 V.
