What the Ritar FT12-100A is for
The Ritar FT12-100A is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 29 kg and M8 terminals.
Dimensions, polarity and mounting
The Ritar FT12-100A is made in the 508 × 111 × 236 mm format and weighs 29 kg. It uses M8 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 FT12-100A: FT range and AGM technology
The FT is the Ritar range the FT12-100A 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.

Warranty and coverage
The Ritar FT12-100A comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.
Care and maintenance
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.

Frequently asked questions
Is the Ritar FT12-100A an AGM battery and what are the benefits of AGM?
Yes: the FT12-100A from Ritar uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It tolerates heat better and handles more cycles than a conventional battery.
What are the dimensions of the Ritar FT12-100A battery?
The Ritar FT12-100A takes up 508×111×236 mm (length, width and height, terminals included). Before buying, measure the space in your device: one extra millimetre can stop the hold-down clamp from closing.
Ritar FT12-100A or Ritar FT12-105: which one to choose?
It is the bigger sister of the FT12-100A in the same Ritar range. Compared with the FT12-100A it has 5 Ah more. It costs 53,00 € more. More capacity means more runtime: worth it if your equipment takes the size and had that capacity or more; otherwise the FT12-100A does the job.
