As many know, KingCom built its name with quality products such as high end handset batteries compatible for most mobile phone units. Aiming to give the best product to their consumers, KingCom’s S!gma Stone is powered by a 3.7 Li-Polymer battery of 1810mAh. Lithium Polymer batteries do not need metal casings, thus it is very light unlike the Lithium Ion. Li-Po batteries also have very low self discharge level unlike its predecessors.
