Description
Description
The SKB SK4-6 is a recombination lead acid battery — commonly described as hermetic or sealed — with 2 cells and a nominal voltage of 4 Vdc. It delivers 6.0 Ah capacity and a 15-minute battery power of 34 W (17 W per cell), making it suitable for general backup and anti-blackout uses.
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 — 2 cells
- 4 Vdc nominal voltage, 6.0 Ah capacity
- Faston 4.8 mm terminals with layout 2
- 200–300 cycles at 100% depth of discharge; up to 1,000 cycles at 30% capacity
- EUROBAT Classification: 3–5 years Standard Commercial
- Usage: General, Anti Blackout
Product Benefits
- The recombination (sealed) design prevents acid spillage and requires no water top-up, making it maintenance-free in installed applications
- A 34 W 15-minute power rating confirms sustained delivery during short outages, not just peak pulse capability
- Memory retention during battery replacement is not a concern — the sealed construction allows normal handling without leakage risk
- The EUROBAT Standard Commercial rating provides a documented lifecycle expectation for planning maintenance schedules
