Chilwee Graphene Battery
FEATURES & BENEFITS
Designed based on Graphene Technology enables the Graphene Battery with the the features of excellent long range, larger power and extremely long life.
Unique structure of battery container and lid to ensure excellent gas recommendation efficiency, less gas released so that water loss rate is reduced.
Sepcial grid alloy material and special lead paste prescription have been utilized to resist corrosion on plates, prolong the life of the battery.
Increased positive active material to improve the battery's initial capacity and service life.
Redesigned battery container and terminal, more attractive appearance and easy for installation.
