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 26 Ah C20 📏 Dimensions 166×175×125 mm ⚙️ Technology AGM ⚖️ Weight 7,4 kg 🏷️ Model RITAR RT ## Description ## Stationary battery Ritar RT12260 RT 26Ah 12V 12*V* Voltage 26*Ah* Capacity 7.40*kg* Weight The **Ritar RT12260** with AGM technology is a **26 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. Its 166 × 175 × 125 mm make it the exact replacement for the 26 Ah battery fitted as standard to many UPS, alarm and emergency systems. - Standard format for UPS and emergency systems. - Low self-discharge and high reliability. - Instant response to mains failures. - AGM: faster recharging and better cycle resistance than a conventional battery. ### What the Ritar RT12260 is for With 26 Ah, the Ritar RT12260 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 7.40 kg and M5 terminals. ### Will it fit your current battery tray? In terms of format, the Ritar RT12260 measures 166 × 175 × 125 mm (length × width × height) and weighs 7.40 kg. It uses M5 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 RT12260 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. ### The Ritar RT12260: RT range and AGM technology The **RT** is the Ritar range the RT12260 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. 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 Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Warranty and coverage The Ritar RT12260 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. ### Delivery times 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 RT12260 an AGM battery and what are the benefits of AGM? Yes. The RT12260 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 RT12260 model? Dimensions (length × width × height) are 166×175×125 mm — also written as 166x175x125 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. ## Equivalent batteries - [Q-battery BATTERY-12LS-24](https://baterias.com/gb/battery-q-battery-12ls-24-12v-24ah) - [Q-battery BATTERY-12LS-26](https://baterias.com/gb/battery-q-battery-12ls-26-12v-26ah) - [Q-battery BATTERY-12LSX-7.5 F2](https://baterias.com/gb/battery-q-battery-12lsx-7_5-f2-12v-24ah) - [RITAR RT12280](https://baterias.com/gb/battery-ritar-rt12280-12v-28ah-rt-agm) ## 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 · 2026-10-31*
