Stationary battery Ritar FT12-105 FT 105Ah 12V
Designed for UPS, alarms, telecoms and emergency lighting, the Ritar FT12-105 from the FT range offers 105 Ah with AGM technology on permanent float charge. Measuring 508 × 111 × 236 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 105 Ah battery of this format.
- Low self-discharge and high reliability.
- 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 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.
Ritar: the maker behind the FT12-105
Ritar is one of the world's largest VRLA battery manufacturers. Its RA, RT, RL, HR and FT series equip UPS, telecoms and solar systems worldwide with very consistent quality. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
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.
Warranty and coverage
The Ritar FT12-105 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.
Shipping, delivery and returns
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Is the Ritar FT12-105 an AGM battery and what are the benefits of AGM?
Yes. The FT12-105 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 is the Ritar FT12-105 battery installed in the vehicle?
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.
How long does the Ritar FT12-105 battery last?
Expected lifespan of the Ritar FT12-105 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 FT12-105 battery?
Dimensions (length × width × height) are 508×111×236 mm — also written as 508x111x236 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 FT12-105 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.
