The **Q-Battery 12LS-90** with AGM technology is a **90 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. Measuring 306 × 169 × 211 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 90 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 12LS-90 is for

With 90 Ah, the Q-Battery 12LS-90 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 29.50 kg and F11 (M6) terminals.

### Technology inside the Q-Battery 12LS-90

Q-Battery builds the 12LS-90 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
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.

### Will it fit your current battery tray?

It has external dimensions of 306 × 169 × 211 mm and weighs 29.50 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

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. All the Q-Battery batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Care and maintenance

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.

### Warranty and coverage

The Q-Battery 12LS-90 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 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. You have **14 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 this battery AGM? What is it for?

Yes. The 12LS-90 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 12LS-90 battery?

Dimensions (length × width × height) are 306×169×211 mm — also written as 306x169x211 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.
