Measuring 151 × 65 × 94 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 7 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. ### What the Q-Battery 12LSX-12 F2 is for With 7 Ah, the Q-Battery 12LSX-12 F2 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 2.30 kg and F1 (4 75mm) terminals. ### Dimensions, polarity and mounting In terms of format, the Q-Battery 12LSX-12 F2 measures 151 × 65 × 94 mm (length × width × height) and weighs 2.30 kg. It uses F1 (4 75mm) terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Q-Battery: the maker behind the 12LSX-12 F2 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. We guarantee that every Q-Battery arrives new, charged and with the manufacturer's full warranty. ### The Q-Battery 12LSX-12 F2: AGM Long Life range and AGM technology Within the Q-Battery catalogue, the **AGM Long Life** series groups the references designed for this use. The 12LSX-12 F2 is the 7 Ah model of that family, with the same performance as its siblings in other sizes. AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### Usage and maintenance tips Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. ### Official warranty The Q-Battery 12LSX-12 F2 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. ### Delivery times and returns Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days.

The 12LSX-12 F2 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. ### What are the dimensions of the Q-battery 12LSX-12 F2 battery? Dimensions (length × width × height) are 151×65×94 mm — also written as 151x65x94 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. ## Equivalent batteries - [Q-battery BATTERY-12LCP-9](https://baterias.com/gb/battery-q-battery-12lcp-9-12v-9ah) - [Q-battery BATTERY-12LS-7.2 F1](https://baterias.com/gb/battery-q-battery-12ls-7_2-f1-12v-72ah) ## 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 · 2026-11-01*
