Stationary battery Ritar HR12-125W HR 33Ah 12V
Designed for UPS, alarms, telecoms and emergency lighting, the Ritar HR12-125W from the HR range offers 33 Ah with AGM technology on permanent float charge. It measures 195 × 130 × 168 mm, the format sought by anyone replacing a 33 Ah battery in UPS, alarm and emergency systems.
- Long float life under permanent charge.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Maintenance-free for its whole service life.
- Sealed and gas-free: suitable for cabinets and offices.
What the Ritar HR12-125W is for
Designed for UPS, alarms, telecoms and emergency lighting, the Ritar HR12-125W 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 10 kg and F11(M6) terminals.
Dimensions, polarity and mounting
In terms of format, the Ritar HR12-125W measures 195 × 130 × 168 mm (length × width × height) and weighs 10 kg. It uses F11(M6) terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
Ritar: the maker behind the HR12-125W
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.
The Ritar HR12-125W: HR range and AGM technology
The HR12-125W is part of the Ritar HR range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.
Usage and maintenance tips
Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. 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 HR12-125W 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 HR12-125W an AGM battery and what are the benefits of AGM?
Yes. The HR12-125W 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 HR12-125W 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 many years does this battery last?
Expected lifespan of the Ritar HR12-125W 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 HR12-125W model?
Dimensions (length × width × height) are 195×130×168 mm — also written as 195x130x168 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 HR12-125W 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.
