A new range of monobloc batteries featuring spiral wound AGM technology, has been introduced by GNB Industrial Power (previously known as Exide). Because the electrolyte of the RECUP (short for recuperation) batteries is suspended in an Absorbed Glass Mat, it means the batteries require no maintenance (including topping up).
The batteries feature large power draws over short durations and are well suited for fast and/or opportunity charging as they can accept a high charge. Applications include electric pallet trucks, automated guided vehicles, hybrid and electric cars (especially those that use regenerative braking), electric boats, go-karts, and cleaning machines.
The spiral wound design gives a greater surface area of positive and negative plate within the cell and is the most efficient way of liberating the stored energy from a lead acid battery. As well as being maintenance-free, they are vibration resistant, can operate effectively in low temperatures and have minimal health and safety implications due to the electrolyte being suspended in a glass microfibre mat. No electrolyte is spilt even if the battery case is damaged. They can also offer 450 charging cycles.
The technology has already been used in electric cars and boats as well as the Project ULTra personal rapid transit system at London Heathrow.
