Stationary battery Ritar FT12-90 FT 90Ah 12V

Designed for UPS, alarms, telecoms and emergency lighting, the Ritar FT12-90 from the FT range offers 90 Ah with AGM technology on permanent float charge. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 563 × 114 × 188 mm format: same 90 Ah capacity.

  • AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
  • Long float life under permanent charge.
  • Sealed and gas-free: suitable for cabinets and offices.
  • Maintenance-free for its whole service life.

What the Ritar FT12-90 is for

The Ritar FT12-90 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 26.50 kg and F6 terminals.

Will it fit your current battery tray?

In terms of format, the Ritar FT12-90 measures 563 × 114 × 188 mm (length × width × height) and weighs 26.50 kg. It uses F6 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 FT12-90

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. We guarantee that every Ritar arrives new, charged and with the manufacturer's full warranty.

The Ritar FT12-90: FT range and AGM technology

Within the Ritar catalogue, the FT series groups the references designed for this use. The FT12-90 is the 90 Ah model of that family, with the same performance as its siblings in other sizes.

AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

Care and maintenance

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 FT12-90 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.

When you get it and how to return it

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 FT12-90 an AGM battery and what are the benefits of AGM?

Yes. The FT12-90 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 fit the FT12-90 model in my device?

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 FT12-90 battery last?

Expected lifespan of the Ritar FT12-90 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 measurements of the FT12-90 model?

Dimensions (length × width × height) are 563×114×188 mm — also written as 563x114x188 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.

Which batteries are equivalent to the Ritar FT12-90?

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.
