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 74 Ah C20 📏 Dimensions 260×169×218 mm ⚙️ Technology AGM ⚖️ Weight 23,5 kg 🏷️ Model RITAR HT ## Description ## Stationary battery Ritar HT12-70 HT 74Ah 12V 12*V* Voltage 74*Ah* Capacity 23.50*kg* Weight The **12 V**, **74 Ah** **Ritar HT12-70** stationary battery from the **HT** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 260 × 169 × 218 mm format: same 74 Ah capacity. - Sealed and gas-free: suitable for cabinets and offices. - Maintenance-free for its whole service life. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Long float life under permanent charge. ### Dimensions, polarity and mounting It has external dimensions of 260 × 169 × 218 mm and weighs 23.50 kg. It uses F15(M6) / F11(M6) terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### What the Ritar HT12-70 is for The Ritar HT12-70 is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 23.50 kg and F15(M6) / F11(M6) terminals. ### The Ritar HT12-70: HT range and AGM technology Within the Ritar catalogue, the **HT** series groups the references designed for this use. The HT12-70 is the 74 Ah model of that family, with the same performance as its siblings in other sizes. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### Ritar: the maker behind the HT12-70 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. All the Ritar batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Official warranty The Ritar HT12-70 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 Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Replace all the batteries in the set at once and avoid environments continuously above 25 °C. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is this battery AGM? What is it for? Yes. The HT12-70 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 HT12-70 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. ### What is the service life of the HT12-70 model? Expected lifespan of the Ritar HT12-70 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 are the dimensions of the Ritar HT12-70 battery? Dimensions (length × width × height) are 260×169×218 mm — also written as 260x169x218 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 HT12-70? 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. ## 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 · 2026-10-22*
