Designed for UPS, alarms, telecoms and emergency lighting, the **Long WP7-12(28W)T** from the **WP WATT Series** range offers **7 Ah** with AGM technology on permanent float charge. Its 151 × 65 × 106 mm make it the exact replacement for the 7 Ah battery fitted as standard to many UPS, alarm and emergency systems.
- Instant response to mains failures.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Standard format for UPS and emergency systems.
- Low self-discharge and high reliability.

### What the Long WP7-12(28W)T is for

Designed for UPS, alarms, telecoms and emergency lighting, the Long WP7-12(28W)T 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 2.19 kg.

### Size, terminals and hold-down of the Long WP7-12(28W)T

The Long WP7-12(28W)T is made in the 151 × 65 × 106 mm format and weighs 2.19 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.

### The Long WP7-12(28W)T: WP WATT Series range and AGM technology

Within the Long catalogue, the **WP WATT Series** series groups the references designed for this use. The WP7-12(28W)T is the 7 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### 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.

### Manufacturer's warranty

The Long WP7-12(28W)T 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

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.

### Delivery times 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 WP7-12(28W)T model AGM? What does this technology offer?

Yes. The WP7-12(28W)T 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 are the dimensions of the Long WP7-12(28W)T battery?

Dimensions (length × width × height) are 151×65×106 mm — also written as 151x65x106 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.
