Li-Po (Lithium Polymer) Radio Batteries

The light weight, longest Lasting, longest running packs we have ever offered!

*Note: Our PolyMax P/N's begin with "CX" not "PM" as the OEM factory uses.

            They are the exact same batteries but with the Criticalbattery Label.


User Testimonial

We first started using your Li-Polymer batteries in July 2011 when we purchased almost 500 units. Our Police and Fire departments runs 12 hour shifts and these batteries last that and more.

   Over the years we have purchased Li-Polymer batteries and are very happy with them.   Dave Patterson's attention to our needs has been excellent. I will be a customer for many years to come.
