No such thing. Our batteries are Rebuilt - when we receive retired battery packs, we first inspect them for physical damage and visible signs of ageing. If they pass the test, all batteries cells are characterised: strict test protocols to determine the quality and performance characteristics of each cell. Those A-grade cells that pass our stringent quality threshold are then grouped into batches of 'like' cells and carefully balanced to create a Rebuilt replacement battery. All batteries are subsequently tested under our quality control protocols before being dispatched to an Authorised Fitter who will install it in your vehicle. Our Authorised Fitters are trained experts who perform a second, independent quality check on our work. All of this is to ensure that we solve your problem, not create new ones.
