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 95 Ah C20 📏 Dimensions 328×172×210 mm ⚙️ Technology AGM ⚖️ Weight 31 kg 🏷️ Model RITAR HT ## Description ## Stationary battery Ritar HT12-90 HT 95Ah 12V 12*V* Voltage 95*Ah* Capacity 31*kg* Weight The **Ritar HT12-90** with AGM technology is a **95 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 328 × 172 × 210 mm format: same 95 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. ### What the Ritar HT12-90 is for With 95 Ah, the Ritar HT12-90 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 31 kg and F5(M8) / F12(M8) terminals. ### Size, terminals and hold-down of the Ritar HT12-90 In terms of format, the Ritar HT12-90 measures 328 × 172 × 210 mm (length × width × height) and weighs 31 kg. It uses F5(M8) / F12(M8) 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 HT12-90: HT range and AGM technology The HT12-90 is part of the Ritar **HT** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### 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. All the Ritar batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The Ritar HT12-90 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. ### Care and maintenance 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 Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic and Canary Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] 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 this battery AGM? What is it for? Yes. The HT12-90 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 HT12-90 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 HT12-90 battery last? Expected lifespan of the Ritar HT12-90 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 HT12-90 battery? Dimensions (length × width × height) are 328×172×210 mm — also written as 328x172x210 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 HT12-90? 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. ## Reviews - **Average rating**: 4.81 / 5 (10 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-28*
