Review on Upgrade Your Two-Way Radio With High Capacity Baofeng Battery Pack BL5 - 2Pcs Set By Mirkit Radio USA Warranty by John Chembola

After contacting the vendor prior to buying the batteries and telling them that I would test them, I still received 2 batteries that were not even as good as the standard Boefeng battery. One battery was 1629 Mah the other was 1700 Mah. I believe that the Chinese manufacturers either have their own standards for defining Mah or they just print up labels to affix to their batteries to make them sell. These batteries are only at 80% of advertised even after a full charge to 8.33 VDc. I will be sending them back and ordering the 3800 Mah batteries that only supply 2800 Mah. this is a sad situation.
