The **Q-Battery 12LS-12 F1** with AGM technology is a **12 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. Measuring 151 × 98 × 95 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 12 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-12 F1 is for

Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-12 F1 is sealed, gas-free and suitable for technical cabinets and offices. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 3.60 kg, F1 (4 75mm) terminals and G112072 hold-down.

### Size, terminals and hold-down of the Q-Battery 12LS-12 F1

It has external dimensions of 151 × 98 × 95 mm and weighs 3.60 kg. It uses a G112072 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

The Q-Battery catalogue runs from small alarm batteries to large traction monoblocs, always with sealed, maintenance-free technology. All the Q-Battery batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Technology inside the Q-Battery 12LS-12 F1

Within the Q-Battery catalogue, the 12LS-12 F1 is the 12 Ah model designed for this application.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

### 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.

### Official warranty

The Q-Battery 12LS-12 F1 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 [[ks:cutoff]]** 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 **[[ks:return_days]] 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-12 F1 an AGM battery and what are the benefits of AGM?

Yes. The 12LS-12 F1 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 is the Q-battery 12LS-12 F1 battery installed in the vehicle?

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 this page. 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-12 F1 battery last?

Expected lifespan of the Q-battery 12LS-12 F1 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-12 F1 battery?

Dimensions (length × width × height) are 151×98×95 mm — also written as 151x98x95 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.

### Which batteries are equivalent to the Q-battery 12LS-12 F1?

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.
