The Long WP26-12N: WP Series range and AGM technology
Within the Long catalogue, the WP Series series groups the references designed for this use. The WP26-12N is the 26 Ah model of that family, with the same performance as its siblings in other sizes.
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.
