Stationary battery Q-Battery 12LS-80 82Ah 12V
The Q-Battery 12LS-80 with AGM technology is a 82 Ah, 12 V backup battery for UPS, alarms, telecoms and emergency lighting. Measuring 350 × 167 × 180 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 82 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-80 is for
The Q-Battery 12LS-80 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 24 kg and F11 (M6) terminals.
Dimensions, polarity and mounting
It has external dimensions of 350 × 167 × 180 mm and weighs 24 kg. It uses 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.
Why choose Q-Battery batteries
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.
Technology inside the Q-Battery 12LS-80
The 12LS-80 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.
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.
Usage and maintenance tips
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.
Manufacturer's warranty
The Q-Battery 12LS-80 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
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 Q-battery 12LS-80 an AGM battery and what are the benefits of AGM?
Yes. The 12LS-80 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 change this battery step by step?
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-80 battery last?
Expected lifespan of the Q-battery 12LS-80 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-80 battery?
Dimensions (length × width × height) are 350×167×180 mm — also written as 350x167x180 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-80 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.
