Long float-life under permanent charge and instant response to mains outages with no noticeable voltage drop. ## Why this stationary battery? - **Instant response** when the mains drop, no voltage dip - **Long life under 24/7 charge** optimised for permanent service - **Compatible with your system** existing UPS units and alarm control panels 🔌 Voltage 12 V ⚡ Capacity 9 Ah C20 📏 Dimensions 151×65×100 mm ⚙️ Technology AGM ⚖️ Weight 2,45 kg 🏷️ Model RITAR HR ## Description ## Stationary battery Ritar HR12-36W HR 9Ah 12V 12*V* Voltage 9*Ah* Capacity 2.45*kg* Weight 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. - 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 1 to 2 working days; for the Balearic Islands and the rest of the European Union allow 1 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, it is AGM. In an AGM battery such as the HR12-36W, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It tolerates heat better and handles more cycles than a conventional battery. ### What size is this battery? It measures 151×65×100 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### Ritar HR12-36W or Ritar HR12-28W: which one to choose? Same family as the HR12-36W, one step down. Compared with the HR12-36W it has 2 Ah less. It costs 4,40 € less. Less runtime: only if the original had that capacity and there is no room for more. ### Ritar HR12-36W or Ritar HR12-32W: which one to choose? It is the smaller sister of the HR12-36W in the same Ritar range. Compared with the HR12-36W it has 1 Ah less. It costs 0,75 € less. Less runtime: only if the original had that capacity and there is no room for more. ## Equivalent batteries - [RITAR HR12-28W](https://baterias.com/gb/battery-ritar-hr12-28w-12v-7ah) - [RITAR HR12-32W](https://baterias.com/gb/battery-ritar-hr12-32w-12v-8ah) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-15*
