Stationary battery Ritar FT12-150 FT 150Ah 12V
The Ritar FT12-150 with AGM technology is a 150 Ah, 12 V backup battery for UPS, alarms, telecoms and emergency lighting. Its 565 × 110 × 296 mm make it the exact replacement for the 150 Ah battery fitted as standard to many UPS, alarm and emergency systems.
- Instant response to mains failures.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Standard format for UPS and emergency systems.
- Low self-discharge and high reliability.
What the Ritar FT12-150 is for
With 150 Ah, the Ritar FT12-150 gives your UPS or emergency system the autonomy it needs. Replace all the batteries in the set at once. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 45 kg and M8 terminals.
The Ritar FT12-150: FT range and AGM technology
Within the Ritar catalogue, the FT series groups the references designed for this use. The FT12-150 is the 150 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?
The Ritar FT12-150 is made in the 565 × 110 × 296 mm format and weighs 45 kg. It uses M8 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.
Ritar: the maker behind the FT12-150
With more than twenty years making sealed lead batteries, Ritar offers general-purpose, long-life, high-rate and front-terminal ranges for every stationary application. All the Ritar batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Usage and maintenance tips
Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
Official warranty
The Ritar FT12-150 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.

Frequently asked questions
Is the Ritar FT12-150 an AGM battery and what are the benefits of AGM?
Yes. The FT12-150 from Ritar uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How do I change this battery step by step?
In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
What is the service life of the FT12-150 model?
Expected lifespan of the Ritar FT12-150 is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the Ritar FT12-150 battery?
Dimensions (length × width × height) are 565×110×296 mm — also written as 565x110x296 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
What are the equivalents of the FT12-150 model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
