The SKB SK6-3.2 is a recombination lead acid battery with 3 cells and a nominal voltage of 6 Vdc. It delivers 3.2 Ah capacity and a 15-minute battery power of 33 W (11 W per cell), suitable for general backup and anti-blackout installations.

The recombination technology allows approximately 200–300 charge cycles at 100% depth of discharge. At 30% of capacity, the battery reaches 1,000 cycles. Charging must be carried out with a constant-voltage charger at the values marked on the battery; the battery must not be left in a discharged state after use.

Key Features

• Sealed recombination lead acid construction — 3 cells
• 6 Vdc nominal voltage, 3.2 Ah capacity
