Stationary battery Ritar HR12-36W HR 9Ah 12V
The 12 V, 9 Ah Ritar HR12-36W stationary battery from the HR range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 151 × 65 × 100 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 9 Ah battery of this format.
In short: the Ritar HR12-36W (9 Ah, 151 × 65 × 100 mm). Verified equivalent alternatives: Ritar HR12-28W and Ritar HR12-32W.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Instant response to mains failures.
- Low self-discharge and high reliability.
- Standard format for UPS and emergency systems.
What the Ritar HR12-36W is for
With 9 Ah, the Ritar HR12-36W 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 2.45 kg and F1 /F2 terminals.
The Ritar HR12-36W: HR range and AGM technology
Within the Ritar catalogue, the HR series groups the references designed for this use. The HR12-36W is the 9 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.
Dimensions, polarity and mounting
In terms of format, the Ritar HR12-36W measures 151 × 65 × 100 mm (length × width × height) and weighs 2.45 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.
What Ritar does differently
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.
Usage and maintenance tips
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 HR12-36W 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
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 HR12-36W model AGM? What does this technology offer?
Yes. The HR12-36W 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 HR12-36W 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 HR12-36W battery last?
Expected lifespan of the Ritar HR12-36W 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 size is this battery?
Dimensions (length × width × height) are 151×65×100 mm — also written as 151x65x100 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 HR12-36W?
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.
