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 18 Ah C20 📏 Dimensions 181×77×167 mm ⚙️ Technology AGM ⚖️ Weight 5,35 kg 🏷️ Model RITAR HR ## Description ## Stationary battery Ritar HR12-70W HR 18Ah 12V 12*V* Voltage 18*Ah* Capacity 5.35*kg* Weight The **12 V**, **18 Ah** **Ritar HR12-70W** stationary battery from the **HR** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Its 181 × 77 × 167 mm make it the exact replacement for the 18 Ah battery fitted as standard to many UPS, alarm and emergency systems. - Instant response to mains failures. - AGM: faster recharging and better cycle resistance than a conventional battery. - Standard format for UPS and emergency systems. - Low self-discharge and high reliability. ### What the Ritar HR12-70W is for With 18 Ah, the Ritar HR12-70W 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 5.35 kg and F3(M5)/F13(M5) terminals. ### Size, terminals and hold-down of the Ritar HR12-70W The Ritar HR12-70W is made in the 181 × 77 × 167 mm format and weighs 5.35 kg. It uses F3(M5)/F13(M5) 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. ### The Ritar HR12-70W: HR range and AGM technology The **HR** is the Ritar range the HR12-70W 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. 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. ### 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. We guarantee that every Ritar arrives new, charged and with the manufacturer's full warranty. ### Official warranty The Ritar HR12-70W 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. ### How to make it last longer 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. ### Shipping, delivery and returns 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 the Ritar HR12-70W an AGM battery and what are the benefits of AGM? Yes. The HR12-70W 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 do I fit the HR12-70W model in my device? 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 this page. 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. ### How long does the Ritar HR12-70W battery last? Expected lifespan of the Ritar HR12-70W 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 measurements of the HR12-70W model? Dimensions (length × width × height) are 181×77×167 mm — also written as 181x77x167 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 HR12-70W? 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. ## Equivalent batteries - [RITAR HR12-50W](https://baterias.com/gb/battery-ritar-hr12-50w-12v-14ah) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-09*
