Black and Decker 9074 Type 4 Battery Replacement

Introduction

I only like to use electric screwdrivers for the assembly of larger screws from larger components. This one has been used on many TV's and Radio's and just did not hold a charge any longer. I decided to get a new battery and replace the old one. Fairly easy and straight forward task. The biggest problem with this job was to find a new battery.
