SKB Lead Acid Battery 12V 9.0Ah SK12-9 - UPS Replacement Battery

The SKB SK12-9 is a 12V 9.0Ah lead-acid replacement battery specifically designed for uninterruptible power supply (UPS) systems and standby power applications. This valve-regulated lead-acid (VRLA) battery utilizes AGM (Absorbent Glass Mat) technology, providing reliable and maintenance-free operation with an expected service life of 10 years under EUROBAT classification standards.

Built with 6 cells in series, this battery delivers 204W of power output at 15-minute discharge rates, making it suitable for backup power in computer systems, networking equipment, and emergency lighting. The battery features 6.3mm Faston terminals with a 4-terminal layout for flexible installation options. It operates across a wide temperature range (-10°C to +60°C for discharge, -20°C to +60°C for charging and storage) and supports both standby (buffer) charging at 13.5-13.8V and cyclic charging at 14.4-15.0V.

Compact dimensions of 151×65×95mm and a lightweight design of 2.60kg make this battery easy to integrate into existing UPS systems. The ABS high-impact plastic container ensures durability and safety, while the maximum discharge current capability of 130A (5-second burst) provides reliable performance during power transitions.
