简介
Here I am rebuilding, actually more building, a battery of the electric screw driver. The original battery is no longer available so I decided to build my own i order to continue to use the screwdriver. The battery cell I am using are 4/5 SC (sub C) size. Meaning they are 4/5 the size of a C-Cell. They are 23 x 34 mm in size with a capacity of 2000mAh and 1.2 Volts.

-
Here is the original battery. Three cells surrounded by a soft plastic sheathing
-
Cut the plastic (I used a utility knife) away.
-
Now the three cells are clearly visible and the way they are connected in series. Meaning positive from one cell to negative on the next cell. Each cell separated by a rubber insulator
-
-
-
Top to bottom on this image shows the insulator that is on the top portion of the cells. Next are the old three cells and bottom the new cells.
-
The contacts on the old cells appear to be spot welded to make the connection.
-
Separate the connections with either a pair of side cutters or a pair of scissor. This will allow you to remove the insulators.
-
-
-
-
All three cells soldered together, positive to negative end, creating a series connection.
-
The original battery was wrapped in some soft plastic. I decided to use 1 1/4 inch heat shrink tubing. Black electric tape might work just as well, but I used what I had on hand.
-
Heatshrink tubing placed over the cells
