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 12 Ah C20 📏 Dimensions 151×98×101 mm ⚙️ Technology AGM ⚖️ Weight 3,5 kg 🏷️ Model RITAR HR ## Description ## Stationary battery Ritar HR12-48WB HR 12Ah 12V 12*V* Voltage 12*Ah* Capacity 3.50*kg* Weight The **Ritar HR12-48WB** with AGM technology is a **12 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. Measuring 151 × 98 × 101 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 12 Ah battery of this format. - Low self-discharge and high reliability. - Standard format for UPS and emergency systems. - AGM: faster recharging and better cycle resistance than a conventional battery. - Instant response to mains failures. ### Size, terminals and hold-down of the Ritar HR12-48WB In terms of format, the Ritar HR12-48WB measures 151 × 98 × 101 mm (length × width × height) and weighs 3.50 kg. It uses F1 / F2 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. ### What the Ritar HR12-48WB is for Designed for UPS, alarms, telecoms and emergency lighting, the Ritar HR12-48WB 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 3.50 kg and F1 / F2 terminals. ### The Ritar HR12-48WB: HR range and AGM technology The HR12-48WB 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. ### Ritar: the maker behind the HR12-48WB 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. We guarantee that every Ritar arrives new, charged and with the manufacturer's full warranty. ### Warranty and coverage The Ritar HR12-48WB 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. ### Usage and maintenance tips Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. ### 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 Ritar HR12-48WB an AGM battery and what are the benefits of AGM? Yes. The HR12-48WB 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. ### What are the measurements of the HR12-48WB model? Dimensions (length × width × height) are 151×98×101 mm — also written as 151x98x101 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. ## 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 · 2026-11-01*
