What the Long WPL45-12N is for
With 45 Ah, the Long WPL45-12N gives your UPS or emergency system the autonomy it needs. Replace all the batteries in the set at once. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 14.60 kg.
Will it fit your current battery tray?
It has external dimensions of 199 × 166 × 171 mm and weighs 14.60 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 WPL45-12N: WPL Series range and AGM technology
The WPL Series is the Long range the WPL45-12N 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.
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.
Warranty and coverage
The Long WPL45-12N 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.
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.

Frequently asked questions
Is this battery AGM? What is it for?
Yes, it is AGM. In an AGM battery such as the WPL45-12N, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. It tolerates heat better and handles more cycles than a conventional battery.
What are the dimensions of the Long WPL45-12N battery?
Before buying, measure the space in your device: one extra millimetre can stop the hold-down clamp from closing. The Long WPL45-12N takes up 199×166×171 mm (length, width and height, terminals included).
