What the Ritar RT1290 is for
Designed for UPS, alarms, telecoms and emergency lighting, the Ritar RT1290 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 2.30 kg and F1/F2 terminals.
Will it fit your current battery tray?
The Ritar RT1290 is made in the 151 × 65 × 100 mm format and weighs 2.30 kg. It uses F1/F2 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
The Ritar RT1290: RT range and AGM technology
The RT is the Ritar range the RT1290 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
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.

How to make it last longer
Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.
