These are part of a newly released maintenance-free range, perfect for use with solar energy off-grid systems. They feature an exceptionally long 7-year warranty.
Measuring 328 x 172 x 222mm and weighing 33kg each, these 135Ah batteries employ carbon-fibre technology, which leads to a longer cycle life and permanently inhibited sulphation of the battery plates, a process which reduces the life and effectiveness of the battery.
