Does the job, lasts me 4 days before I need to charge. A good price for a two pack, in August 2020 it was $8.99. The length of the cable is just right as sometimes it's too long and you can't close the battery compartment. I don't know about the 2200mAh rating? The package contains 3 AA batteries, divide 2200 by 3, we get 733 mAh batteries. This is an odd number for a battery.
