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 17 Ah C20 📏 Dimensions 181×77×167 mm ⚙️ Technology AGM ⚖️ Weight 5,7 kg 🏷️ Model AGM STANDARD ## Description ## Stationary battery Q-Battery 12LS-17 17Ah 12V 12*V* Voltage 17*Ah* Capacity 5.70*kg* Weight The **12 V**, **17 Ah** **Q-Battery 12LS-17** stationary battery with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. It measures 181 × 77 × 167 mm, the format sought by anyone replacing a 17 Ah battery in UPS, alarm and emergency systems. - Long float life under permanent charge. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Maintenance-free for its whole service life. - Sealed and gas-free: suitable for cabinets and offices. ### What the Q-Battery 12LS-17 is for Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-17 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 5.70 kg, F13 (M5) terminals and G112073 hold-down. ### Technology inside the Q-Battery 12LS-17 Within the Q-Battery catalogue, the 12LS-17 is the 17 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. ### Dimensions, polarity and mounting The Q-Battery 12LS-17 is made in the 181 × 77 × 167 mm format and weighs 5.70 kg. It uses a G112073 hold-down and 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. ### 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### 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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Manufacturer's warranty The Q-Battery 12LS-17 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. ### When you get it and how to return it 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 the 12LS-17 model AGM? What does this technology offer? Yes. The 12LS-17 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-17 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 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-17 battery last? Expected lifespan of the Q-battery 12LS-17 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 size is this battery? 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 Q-battery 12LS-17? 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-12LSX-7 F1](https://baterias.com/gb/battery-q-battery-12lsx-7-f1-12v-17ah) ## 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 · 2026-09-29*
