12V Battery and Charger Upgrade Guide Video
In this video you will see I rebuild 12 battery with lithium battery for Black & Decker Impact driver. And I also modify the charger from Nicd charger to Lithium charger.

I hope you find something useful & enjoy this video!
I am happy to receive your feedback, advice, suggestions to improve myself.
!!! I apologize for the mistake if I have made in this restoration !!!
