What the Long WPL125-12RN is for

With 125 Ah, the Long WPL125-12RN 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 39.60 kg.

Dimensions, polarity and mounting

The Long WPL125-12RN is made in the 408 × 177 × 224 mm format and weighs 39.60 kg. 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.

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. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty.

The Long WPL125-12RN: WPL Series range and AGM technology

Within the Long catalogue, the WPL Series series groups the references designed for this use. The WPL125-12RN is the 125 Ah model of that family, with the same performance as its siblings in other sizes.

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.

Care and maintenance

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.

Official warranty

The Long WPL125-12RN 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.
