What the Ritar HR12-20BW is for
With 5 Ah, the Ritar HR12-20BW 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 1.60 kg and F1 / F2 terminals.
Will it fit your current battery tray?
The Ritar HR12-20BW is made in the 152 × 50 × 101 mm format and weighs 1.60 kg. It uses F1 / F2 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 HR12-20BW
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
The Ritar HR12-20BW: HR range and AGM technology
The HR is the Ritar range the HR12-20BW 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.
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.
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. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.
Warranty and coverage
The Ritar HR12-20BW 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 1 to 2 working days, the islands and the rest of the EU in 1 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 HR12-20BW model AGM? What does this technology offer?
Yes, it is AGM. In an AGM battery such as the HR12-20BW, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It withstands more cycles than a conventional battery and copes better with heat.
What are the measurements of the HR12-20BW model?
Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 152×50×101 mm in length × width × height, with the terminals included in the height.
