The **12 V**, **45 Ah** **Long WPS45-12** stationary battery from the **WPS Series** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. It measures 197 × 166 × 171 mm, the format sought by anyone replacing a 45 Ah battery in UPS, alarm and emergency systems.
- Long float life under permanent charge.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Maintenance-free for its whole service life.
- Sealed and gas-free: suitable for cabinets and offices.

### What the Long WPS45-12 is for

The Long WPS45-12 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 13.50 kg.

### The Long WPS45-12: WPS Series range and AGM technology

The WPS45-12 is part of the Long **WPS Series** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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?

The Long WPS45-12 is made in the 197 × 166 × 171 mm format and weighs 13.50 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### Why choose Long batteries

Long batteries combine large-scale production with ISO quality standards and a batch-to-batch consistency that has made them the de-facto standard in backup systems and electric mobility. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Care and maintenance

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.

### Manufacturer's warranty

The Long WPS45-12 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 WPS45-12 model AGM? What does this technology offer?

Yes. The WPS45-12 from Long 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 size is this battery?

Dimensions (length × width × height) are 198×166×171 mm — also written as 198x166x171 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.
