6-DZF-22 large power VRLA battery

​Chilwee Graphene Battery Series high energy VRLA Battery is specially designed based on Graphene Technology, which has obviously improve the battery's capacity, output power, cycle life and high/low temperature performance. The ​Chilwee Graphene Battery Series provides longer range, larger power and extremely long life for motive power applications, i.e. electric bicycles, electric tricycles, electric motorcycles and other device require DC power source.

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.
