### What the Q-Battery 12LS-3.4 is for

With 3.4 Ah, the Q-Battery 12LS-3.4 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 1.35 kg, F1 (4 75mm) terminals and G112069 hold-down.

### Size, terminals and hold-down of the Q-Battery 12LS-3.4

In terms of format, the Q-Battery 12LS-3.4 measures 134 × 67 × 60 mm (length × width × height) and weighs 1.35 kg. It uses a G112069 hold-down and F1 (4 75mm) 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.

### Technology inside the Q-Battery 12LS-3.4

The 12LS-3.4 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.

### Q-Battery: the maker behind the 12LS-3.4

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.

### Warranty and coverage

The Q-Battery 12LS-3.4 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.

### Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.

### Shipping, delivery 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. 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 the Q-battery 12LS-3.4 an AGM battery and what are the benefits of AGM?

Yes. The Q-battery 12LS-3.4 is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better.

### What are the measurements of the 12LS-3.4 model?

The Q-battery 12LS-3.4 takes up 134×67×61 mm (length, width and height, terminals included). Before buying, measure the space in your device: one extra millimetre can stop the hold-down clamp from closing.
