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 33 Ah C20 📏 Dimensions 195×130×168 mm ⚙️ Technology AGM ⚖️ Weight 10 kg 🏷️ Model RITAR HR ## Description ## Stationary battery Ritar HR12-125W HR 33Ah 12V 12*V* Voltage 33*Ah* Capacity 10*kg* Weight 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. ### 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. ## 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*
