Powerhouse 12v 40Ah Sealed Lead Acid (SLA) Battery

SKU: 15.021.0340

Availability: Special Buy-In




This 12V 40Ah 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 M5 bolt and nut terminals, 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.
