Bosch 12V 27Ah Sealed Lead-Acid Battery (IPS-BAT12V-27AH) - Rechargeable, Maintenance-Free

Keep your backup power system reliable with the Bosch 12V 27Ah Sealed Lead-Acid Battery. Designed as a dry-cell, maintenance-free power source, this rechargeable battery is a common choice for backing up alarm panels, access control systems, UPS units and other equipment that needs dependable standby power.

Its shock-resistant plastic enclosure protects the internal cells during transport and installation, while the sealed design means there's no need to top up fluid or perform regular maintenance. Because it's a valve-regulated lead-acid design, it can be mounted and used in virtually any position without leaking, which gives installers more flexibility when fitting it into equipment enclosures.

Good to know

The low self-discharge rate means the battery holds its charge well while sitting in standby, so it's ready to deliver power when mains electricity fails rather than needing frequent top-up charging. As with any sealed lead-acid battery, capacity gradually declines with age and charge cycles, so periodic testing of backup batteries is good practice to confirm they'll perform when you actually need them, particularly given South Africa's loadshedding.
