Why Choose Polymer Batteries?

Good Safety Performance Aluminum-plastic flexible packaging prevents explosions; it only air-blasts under extreme conditions.

Ultra-Thin Design Thickness can be less than 1mm, ideal for credit-card-sized devices and slim mobile phones.

Light Weight 40% lighter than steel shell and 20% lighter than aluminum shell batteries of the same capacity.

High Capacity Offers 10-15% higher capacity than equivalent steel shell batteries.

Small Internal Resistance Lower self-consumption and longer standby time for portable electronics.

Customizable Shapes Flexible manufacturing allows for custom dimensions tailored to your device casing.
