Casil UC1270 12V 7AH Sealed Lead Acid Battery for Alarm Panels and Access Control

The 12V 7AH VRLA battery is the most widely used standby battery size in UK security and fire alarm systems. It is the standard battery specified in intruder alarm control panels (Texecom, Pyronix, Ajax hubs with external power, and similar), fire alarm panels (conventional and addressable), access control system power supplies, and small UPS backup units.

VRLA (Valve Regulated Lead Acid) sealed construction means the battery is maintenance-free: no electrolyte top-up is required, no spillage risk during handling or transport, and the sealed gas-recombination design is safe for installation in enclosed equipment cabinets.

The 7AH capacity provides the standby current backup duration specified in EN 50131 for intruder alarm systems (minimum 12 hours standby) when connected to a panel with appropriate quiescent current draw. Actual standby duration depends on the total current draw of the connected system.

Battery replacement is a routine maintenance item for alarm systems: VRLA batteries in alarm applications typically require replacement every three to five years under normal service conditions. The Casil UC1270 is a like-for-like replacement for any 12V 7AH VRLA battery of the same physical dimensions.

Polarity and terminal type should be confirmed before installation: most UK alarm panels use F1 (4.75mm) spade terminals, and the battery should be connected with correct polarity to the charging circuit.
