Single-use batteries are toxic to the environment and expensive to continuously replace. Our mission at Sunlabz is to offer a more effective, energy efficient, and affordable alternative to traditional batteries. Our NiMH cells can be used and recharged 1000 times over, and surpass alkaline batteries in energy density every time. The negative electrodes use a hydrogen absorbing alloy, giving NiMH batteries 2 to 3 times the capacity of an equivalently sized NiCD. Our NiMH cells have an energy density approaching that of a lithium cell.
