VRLA Battery 12V 18AH | Dimension: 181x77x167x167mm
GRANKIA FG18-12 valve regulated sealed lead acid 12v 18ah battery has been specifically designed for general purpose and standby applications. Lead acid 12v 18ah battery offers excellent performance in a wide range of applications. It is including security and fire systems, medical devices, emergency lighting and UPS systems.
The grid structure of the lead acid battery is made from a lead alloy. This battery is a premier, general duty sealed lead-acid battery using absorbent glass mat (AGM) technology to suspend electrolyte in a leak-proof, maintenance-free design.
An 18 Ah battery can produce a current which, when multiplied by the time (in hours) the battery can supply it, equals 18.
So your 12V 18ah battery is actually a ~216 watt hour battery. Watts=Amps×Volts, so Amps taken by the bulb = 25/12= 2.1 Amps. The battery will power the bulb 18/2.1 hours=8.57 hours approximately.
The 12V 18.00Ah battery offers excellent performance in a wide range of applications including security and fire systems, medical devices, emergency lighting and UPS systems.
