• Standard format for UPS and emergency systems.
• AGM: faster recharging and better cycle resistance than a conventional battery.
• Instant response to mains failures.

What the Ritar HR12-28W is for

Designed for UPS, alarms, telecoms and emergency lighting, the Ritar HR12-28W is sealed, gas-free and suitable for technical cabinets and offices. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.08 kg and F1 / F2 terminals.

The Ritar HR12-28W: HR range and AGM technology

Within the Ritar catalogue, the HR series groups the references designed for this use. The HR12-28W is the 7 Ah model of that family, with the same performance as its siblings in other sizes.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Will it fit your current battery tray?

It has external dimensions of 151 × 65 × 100 mm and weighs 2.08 kg. It uses F1 / F2 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
