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 78 Ah C20 📏 Dimensions 260×169×210 mm ⚙️ Technology AGM ⚖️ Weight 23,5 kg 🏷️ Model AGM STANDARD ## Description ## Stationary battery Q-Battery 12LS-75 78Ah 12V 12*V* Voltage 78*Ah* Capacity 23.50*kg* Weight The **12 V**, **78 Ah** **Q-Battery 12LS-75** stationary battery with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 260 × 169 × 210 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 78 Ah battery of this format. - Low self-discharge and high reliability. - Standard format for UPS and emergency systems. - AGM: faster recharging and better cycle resistance than a conventional battery. - Instant response to mains failures. ### Size, terminals and hold-down of the Q-Battery 12LS-75 In terms of format, the Q-Battery 12LS-75 measures 260 × 169 × 210 mm (length × width × height) and weighs 23.50 kg. It uses F11 (M6) terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### What the Q-Battery 12LS-75 is for Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-75 is sealed, gas-free and suitable for technical cabinets and offices. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 23.50 kg and F11 (M6) terminals. ### Technology inside the Q-Battery 12LS-75 Q-Battery builds the 12LS-75 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position. 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. ### Q-Battery: the maker behind the 12LS-75 The Q-Battery catalogue runs from small alarm batteries to large traction monoblocs, always with sealed, maintenance-free technology. We guarantee that every Q-Battery arrives new, charged and with the manufacturer's full warranty. ### Manufacturer's warranty The Q-Battery 12LS-75 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 Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### 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 12LS-75 model AGM? What does this technology offer? Yes. The 12LS-75 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 do I fit the 12LS-75 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 Q-battery 12LS-75 battery last? Expected lifespan of the Q-battery 12LS-75 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-75 battery? Dimensions (length × width × height) are 260×169×210 mm — also written as 260x169x210 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. ### What are the equivalents of the 12LS-75 model? 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 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-12*
