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 26 Ah C20 📏 Dimensions 165×176×125 mm ⚙️ Technology AGM ⚖️ Weight 8 kg 🏷️ Model AGM STANDARD ## Description ## Stationary battery Q-Battery 12LS-26 26Ah 12V 12*V* Voltage 26*Ah* Capacity 8*kg* Weight Designed for UPS, alarms, telecoms and emergency lighting, the **Q-Battery 12LS-26** offers **26 Ah** with AGM technology on permanent float charge. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 165 × 176 × 125 mm format: same 26 Ah capacity. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Long float life under permanent charge. - Sealed and gas-free: suitable for cabinets and offices. - Maintenance-free for its whole service life. ### What the Q-Battery 12LS-26 is for The Q-Battery 12LS-26 is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 8 kg, F13 (M5) terminals and G112076 hold-down. ### Technology inside the Q-Battery 12LS-26 The 12LS-26 is one of the Q-Battery references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue. 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. ### Size, terminals and hold-down of the Q-Battery 12LS-26 The Q-Battery 12LS-26 is made in the 165 × 176 × 125 mm format and weighs 8 kg. It uses a G112076 hold-down and F13 (M5) 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 Q-Battery does differently 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. ### 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. ### Official warranty The Q-Battery 12LS-26 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. ### Shipping, delivery and returns Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### Is the Q-battery 12LS-26 an AGM battery and what are the benefits of AGM? Yes, it is AGM. In an AGM battery such as the 12LS-26, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It tolerates heat better and handles more cycles than a conventional battery. ### What size is this battery? Check the room available in your device, because a single millimetre too much can stop the clamp from closing. Its dimensions are 165×176×125 mm, also written 165x176x125 mm; the height already includes the terminals. ### Q-battery BATTERY-12LS-26 or Q-battery BATTERY-12LS-24: which one to choose? The leaner option in the same range, below the BATTERY-12LS-26. Compared with the BATTERY-12LS-26 it has 2 Ah less. It costs 10,10 € more. Less runtime: only if the original had that capacity and there is no room for more. ### Q-battery BATTERY-12LS-26 or Q-battery BATTERY-12LSX-7.5 F2: which one to choose? Same family as the BATTERY-12LS-26, one step down. Compared with the BATTERY-12LS-26 it has 2 Ah less. It costs 64,00 € less. Less runtime: only if the original had that capacity and there is no room for more. ## Equivalent batteries - [RITAR RT12260](https://baterias.com/gb/battery-ritar-rt12260-12v-26ah-rt-agm) - [Q-battery BATTERY-12LS-24](https://baterias.com/gb/battery-q-battery-12ls-24-12v-24ah) - [Q-battery BATTERY-12LSX-7.5 F2](https://baterias.com/gb/battery-q-battery-12lsx-7_5-f2-12v-24ah) - [RITAR RT12280](https://baterias.com/gb/battery-ritar-rt12280-12v-28ah-rt-agm) ## 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 · 2026-11-12*
