The **12 V**, **7.5 Ah** **Q-Battery 12LSX-17** stationary battery from the **AGM Long Life** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Its 151 × 65 × 94 mm make it the exact replacement for the 7.5 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.

### Will it fit your current battery tray?

The Q-Battery 12LSX-17 is made in the 151 × 65 × 94 mm format and weighs 2.30 kg. It uses F2 (6 35mm) 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.

### What the Q-Battery 12LSX-17 is for

The Q-Battery 12LSX-17 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 2.30 kg and F2 (6 35mm) terminals.

### The Q-Battery 12LSX-17: AGM Long Life range and AGM technology

The **AGM Long Life** is the Q-Battery range the 12LSX-17 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
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.

### 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.

### Warranty and coverage

The Q-Battery 12LSX-17 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.

### How to make it last longer

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.

### Shipping, delivery 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 12LSX-17 model AGM? What does this technology offer?

Yes. The 12LSX-17 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 12LSX-17 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 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 many years does this battery last?

Expected lifespan of the Q-battery 12LSX-17 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 measurements of the 12LSX-17 model?

Dimensions (length × width × height) are 151×65×94 mm — also written as 151x65x94 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 12LSX-17 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.
