Stationary battery Q-Battery 12LS-1.2 1.2Ah 12V
Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-1.2 offers 1.2 Ah with AGM technology on permanent float charge. Its 97 × 43 × 52 mm make it the exact replacement for the 1.2 Ah battery fitted as standard to many UPS, alarm and emergency systems.
- Standard format for UPS and emergency systems.
- Low self-discharge and high reliability.
- Instant response to mains failures.
- AGM: faster recharging and better cycle resistance than a conventional battery.
What the Q-Battery 12LS-1.2 is for
With 1.2 Ah, the Q-Battery 12LS-1.2 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 0.54 kg, F1 (4 75mm) terminals and G112106 hold-down.
Dimensions, polarity and mounting
In terms of format, the Q-Battery 12LS-1.2 measures 97 × 43 × 52 mm (length × width × height) and weighs 0.54 kg. It uses a G112106 hold-down and 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.
Why choose Q-Battery batteries
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.
Technology inside the Q-Battery 12LS-1.2
Q-Battery builds the 12LS-1.2 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
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.
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-1.2 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
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-1.2 an AGM battery and what are the benefits of AGM?
Yes. The 12LS-1.2 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-1.2 battery last?
Expected lifespan of the Q-battery 12LS-1.2 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-1.2 battery?
Dimensions (length × width × height) are 97×43×52 mm — also written as 97x43x52 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-1.2 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.
