12*V* Voltage
26*Ah* Capacity
8*kg* Weight

The **Long WPL26-12NB** with AGM technology is a **26 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 166 × 175 × 125 mm format: same 26 Ah capacity.
- Sealed and gas-free: suitable for cabinets and offices.
- Maintenance-free for its whole service life.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Long float life under permanent charge.

### What the Long WPL26-12NB is for

The Long WPL26-12NB 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 8 kg.

### Dimensions, polarity and mounting

The Long WPL26-12NB is made in the 166 × 175 × 125 mm format and weighs 8 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

### What Long does differently

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.

### The Long WPL26-12NB: WPL Series range and AGM technology

The **WPL Series** is the Long range the WPL26-12NB 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 (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.

### How to make it last longer

Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.

### Manufacturer's warranty

The Long WPL26-12NB 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

Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### Is the Long WPL26-12NB an AGM battery and what are the benefits of AGM?

Yes, it is AGM. In an AGM battery such as the WPL26-12NB, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It withstands more cycles than a conventional battery and copes better with heat.

### What size is this battery?

Length × width × height: 166x175x125 mm. Height is measured to the top of the terminals. Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.
