This 12V 9Ah sealed lead acid (SLA) battery is one of the most common size SLA batteries in use. It is commonly used in NBN boxes, 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.

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.

Excessive temperatures over 65ºC can effect the ABS housing. Need to be well ventilated in warm conditions. Not for use in engine bays.
