Lots of good information from people, Thanks. I've bookmarked
several sites for future access.
I've checked out most of the sites suggested. Pak rebuilding
will be in the future. For those paks that I can't get inside
I've decided to go three ways here. With one pak I'm going to
rebuild it myself. The case is just snapped together. The
cells are available from Digi Key for $2.50 CDN each (10
required).
Pak number two will be replaced with one of those discount no
name ones.
Pak number three may be rebuilt
I want to check the reliablity of the no name pak the rebuilds
and my own assembly.
I used to rebuild battery paks for the RC hobby shops here in
town. I still have my battery cycler, and tester, and can
verify the capacity of the battery paks as they age.
For the poster that suggested that it might be the charger, it's
not. I hand charged the battery pak on my bench power supply
then cycled them on my tester. The reason all three went is
because I cycle through them, one after the other. They
actually arn't totally dead, they just don't last very long.
By the way,
The new Li_Ion battery paks won't be repairable. They have
micros built right into the battery pak, no replacing of cells,
when they die. The replacement Li-Ion cell for my cellphone was
$79.00 CDN, and that's for a very small battery!!
This is no indication that anything about them is the same other than size
and that they are a NiCad.

Now that sounds interesting. When you say "same cells" are you
refering to the physical size, or a brand name/model.

give it a try, you sure can't beat the price.
I suspect these are Chinese made, as is a lot of PA stuff, but
then most things are now a days.
Thanks for the post

go to princess auto ... get their cheap no-name 18volt battery for
12$ and strip it down. It uses the same 1.2volt cells as my 14.4
dewalt and prob many others .... they may have a lower mah rating but
for the price, what the hell..its worth it. and you have a few spare
cells left over.
i have rebuilt all 3 of mine with these cells and they work just fine

they are the same physical dimensions and they are the same
1.2volts... theer was no name on the dewalt cell .. on the donor
cells there was some unknown name ... the first thing to do is to open
both cases. the dewalt uses torx screws btw. the cells are induction
welded together with metal strips . strip down the new battery first
..you can just peel the strips off the cells with a little effort ..
and position the new cells in the host case in the proper orientation.
I reused the metal strips but you could use wire i suppose. DON'T use
acid core solder!
a bit of liquid flux is a big help too.
as i said... i suspect the MaH rating of the new cells is a bit lower,
but the price more than makes up for that.
