The AllSpark 12V 5Ah Lithium Alarm Battery (AS-512BATLIALARM) delivers the equivalent capacity of an 8Ah lead-acid battery in a compact, lightweight package weighing just 1kg — roughly half the weight of its lead-acid counterpart. Built on LiFePO4 lithium chemistry, it operates at a rated voltage of 12.8V, supports a peak discharge current of 150A (5 seconds), and is engineered for a life expectancy of over 10 years, far outlasting conventional sealed lead-acid cells. At just 150 × 64 × 94mm, it's a direct drop-in replacement for standard alarm battery housings and comes supplied with bolt-on spade terminals for a hassle-free swap.

Designed and manufactured for Australian conditions, this battery is the ideal upgrade for caravan trailer brake breakaway controllers, NBN battery backups, and 12V alarm systems in homes, vehicles, and off-road setups. Whether you're heading off the beaten track in your 4WD, keeping your caravan or motorhome's safety systems charged between trips, or maintaining backup power in a remote rural property, the AllSpark lithium alarm battery offers reliable, maintenance-free performance that stands up to the heat and vibration of Australian roads and outback adventures.
