Stationary battery Ritar RL2800 RL 800Ah 2V
The Ritar RL2800 with AGM technology is a 800 Ah, 2 V backup battery for UPS, alarms, telecoms and emergency lighting. Its 285 × 171 × 342 mm make it the exact replacement for the 800 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.
Will it fit your current battery tray?
It has external dimensions of 285 × 171 × 342 mm and weighs 39 kg. It uses F10(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.
What the Ritar RL2800 is for
Designed for UPS, alarms, telecoms and emergency lighting, the Ritar RL2800 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 39 kg and F10(M8) terminals.
The Ritar RL2800: RL range and AGM technology
Within the Ritar catalogue, the RL series groups the references designed for this use. The RL2800 is the 800 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.
Why choose Ritar batteries
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.
Manufacturer's warranty
The Ritar RL2800 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
Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
Delivery times and returns
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
Is the RL2800 model AGM? What does this technology offer?
Yes: the RL2800 from Ritar uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better.
What are the measurements of the RL2800 model?
Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 285×171×342 mm in length × width × height, with the terminals included in the height.
