A 12 V 7.5 Ah sealed lead-acid battery — the standard size inside most desktop UPS units, and also used in alarm panels, emergency lights, CCTV backup and small security systems.
Match the voltage and the terminal type exactly; the amp-hour rating decides how long the backup lasts. A UPS that beeps or cuts out after a few seconds almost always needs a new battery rather than a new UPS.
Also stocked in 12 V 9 Ah and 12 V 1.3 Ah. Stocked at WPL Trading, No. 305, Kandy Road, Warakapola, with island-wide delivery. Call +94 71 302 4843.
