Description
Description
The SK12-9 is a valve-regulated lead-acid (VRLA) recombination battery. This construction recombines the gases produced during charging back into water, so the battery is sealed and maintenance-free — no need to check or top up electrolyte. Despite the hermetic labelling, it is a recombination design.
Charging must be performed with a constant-voltage charger strictly following the values on the battery label. Incorrect voltage causes immediate deterioration. The battery must be recharged promptly after use and must not be left in a discharged state.
Key Features
- 12 V / 9 Ah sealed recombination lead battery
- 6 cells
- Faston 6.3 mm terminals in layout 4
- Compatible with general and UPS applications
- Approximately 200–300 cycles at 100% depth of discharge; up to 1,000 cycles at 30% depth
- EUROBAT Classification: 3–5 years Standard Commercial
Product Benefits
- Sealed recombination construction means no electrolyte maintenance and no venting requirements — can be mounted in any orientation
- The 200–300 cycle rating at full discharge makes it practical for alarm systems and UPS units that occasionally draw the battery fully
- Up to 1,000 cycles at 30% depth of discharge significantly extends calendar life in standby-float applications such as UPS
- Faston 6.3 mm terminals are a standard connector size, compatible with off-the-shelf quick-disconnect leads
- Buffer charging voltage of 13.5–13.8 Vdc makes it compatible with the float-charge output of most standard UPS chargers
