The battery pack for my SKIL Twist Cordless Screw Driver is dead.
Measures 4.3 volts but will not accept a charge.

I want to replace the NiCd cells myself. However, I need help that
explains how to open the battery pack and change the 3 NiCd cells.

This is a model 2207 3.6v unit. The battery part number is 92940 Flex
Charge Battery.

Thanks, Dave_s

The one time I took apart a battery screw driver, it wasn't
at all dificult to figure out. Please be sure to check
prices on the entire unit before ordering the battery.
Sadly, it's often cheaper to replace the entire thing. I'd
save the old one for parts. The new one might get a bad
switch, or charge plug.

The unit has 3, 1.2v batteries which at full charge should have about
4v, so how you get 4.3v and the unit wont even run is a mystery, you
have a different problem,and its a Skill so im not suprised.

I'll remeasure the no load voltage with my more trust worthy FLUKE DVM.
First measurement was made with a low cost 3 1/2 digit DVM.

Still need info to help open the battery pack case to remove and
replace the 3 1.2volt cells. There must be a way to open the case so
case can be reloaded and used again.

Any info on what the two metal contacts connect to internally that I
see on the fully assembled drill? They measure 0.5 volts until switch is
pushed. Then measure zero volts.

Some one else suggested that the NiCd cells are dried out which is
causing them to not be able to deliver needed current under load?

I did remeasure the battery pack with my FLUKE 4 1/2 digit DVM.
At no load, the total three cell voltage is 4.034 volts. The only single
cell I could access measured 1.34 volts at no load.

Still need help.

PRIMECELL.COM rebuilds battery packs very affordably. They often have
more capacity than your old battery when it was brand new.

they weld rather than solder the straps to the cells, soldering can
damage you new cells.

primecell costs not much more than my just buying the cells
individually, they are well worth the money.

my battery pack came back sparling they must of buffed it, it looked
brand new.

Is it worth the effort? Some days it isn't worth chewing through the
restraints.

Take the tool to an authorized Skil service center in the Baltimore
area.

Looked into something like this for my electric toothbrush.
Found you tube video. I was doable but not easy. Figured that if I
jumped through the hoops to do it, the thing had a few years on it and
other parts would be worn so I just tossed and bought another.
Tossed an old Timex for the same reason. Impossible to remove screws to
access and watch showed lots of wear so I tossed it.

I also have a brother-in-law, retired electrical engineer, that likes to
mess around with old used stuff like this and sometimes send him a care
package of such items. He loves it.
