Alarm Batteries & Power Supplies

Alarm batteries and power supply units for reliable standby power and backup in intruder alarm systems. Our range includes 12V 7Ah sealed lead-acid (SLA) batteries, 12V 2.2Ah and 17Ah SLA options, NiMH rechargeable battery packs, and dedicated alarm PSUs with battery charging circuits for domestic and commercial alarm panels.
EN 50131-6 requires intruder alarm systems to maintain operation during mains power failure, making battery backup essential for compliance. We stock SLA batteries compatible with Texecom, Pyronix, Ajax, Risco, and other major alarm platforms. Alarm PSUs are available in 1A, 2A, and 3A output ratings to suit different panel and device loads. Evolution Electronics supplies alarm batteries and PSUs with fast UK dispatch and competitive trade pricing.
