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 65 Ah C20 📏 Dimensions 350×166×179 mm ⚙️ Technology AGM ⚖️ Weight 20,8 kg 🏷️ Model AGM STANDARD ## Description ## Stationary battery Q-Battery 12LS-65 65Ah 12V 12*V* Voltage 65*Ah* Capacity 20.80*kg* Weight The **12 V**, **65 Ah** **Q-Battery 12LS-65** stationary battery with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 350 × 166 × 179 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 65 Ah battery of this format. - AGM: faster recharging and better cycle resistance than a conventional battery. - Instant response to mains failures. - Low self-discharge and high reliability. - Standard format for UPS and emergency systems. ### What the Q-Battery 12LS-65 is for With 65 Ah, the Q-Battery 12LS-65 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 20.80 kg, F11 (M6) terminals and G112079 hold-down. ### Will it fit your current battery tray? It has external dimensions of 350 × 166 × 179 mm and weighs 20.80 kg. It uses a G112079 hold-down and 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. ### Technology inside the Q-Battery 12LS-65 Within the Q-Battery catalogue, the 12LS-65 is the 65 Ah model designed for this application. 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 Q-Battery does differently Q-Battery specialises in AGM and GEL VRLA batteries for UPS, telecoms, solar and deep cycling, with long-life and tubular-plate series for industrial use. All the Q-Battery batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The Q-Battery 12LS-65 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 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. ### Shipping, delivery and returns Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 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 **14 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 12LS-65 model AGM? What does this technology offer? Yes. The 12LS-65 from Q-battery 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 Q-battery 12LS-65 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. ### How long does the Q-battery 12LS-65 battery last? Expected lifespan of the Q-battery 12LS-65 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 Q-battery 12LS-65 battery? Dimensions (length × width × height) are 350×166×179 mm — also written as 350x166x179 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 Q-battery 12LS-65? 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 - [Q-battery BATTERY-12LS-80](https://baterias.com/gb/battery-q-battery-12ls-80-12v-82ah) ## 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 · 2026-10-27*
