This 12V 4.5Ah sealed lead acid (SLA) battery is a compact battery
for powering 12V equipment. It is commonly used in battery back up
systems, alarm and communications systems and UPS units. Fitted with
4.8mm spade connection tabs, these batteries are easily user replaced in
most equipment they are used in. Cells are fully sealed to prevent any
leakage of electrolyte. UN Number: UN 2800 Non-Spillable - Hazard Class
8.
Our range of Powerhouse SLA batteries are from a quality supplier
and are graded for use in UPS systems. We have found the quality of SLA
batteries varies considerably between suppliers and often cheaper units
have a shorter life span.
PLEASE NOTE: Excessive temperatures over 65ºC can effect the ABS housing. Need to be well ventilated in warm conditions. Not for use in engine bays.
