What the Ritar FT12-105 is for
Designed for UPS, alarms, telecoms and emergency lighting, the Ritar FT12-105 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 32.50 kg and M8 terminals.
The Ritar FT12-105: FT range and AGM technology
The FT12-105 is part of the Ritar FT range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.
Size, terminals and hold-down of the Ritar FT12-105
In terms of format, the Ritar FT12-105 measures 508 × 111 × 236 mm (length × width × height) and weighs 32.50 kg. It uses M8 terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.
