What do you think about just replacing the batteries inside with new Ni-Cads
from the store? Any problems just soldering them together, or should I buy
"shaver" batteries with the terminals built in, though they are much more
money?
Here in Canada a replacement bat pac for a BC80xlt costs over $100.00 with
tax at Ratty Ole Shack, and their rebuild service costs just under the
$100!!! Perhaps there are Canadian readers here who can direct me to a cheap
supply??
Thanks all.

Most batteries are very difficult to solder to if they do not have the
solder tabs built on. The material does not seem to take solder very well
and also you can over heat the battery. The solder tabs are usually spot
welded on.

Thanks Ralph. We recycle here so I have a few to experiment on.
No suggestions for Canada dealers, What about prices in USA?

I've "roughed" up the ends of nicads a bit - scratching them with a knife or
sandpaper or whatever, then spot "soldered" or "tinned" them prior to adding
any leads. I've had pretty good success doing that. Some cells do give
trouble not wanting to take solder, but most have done ok. IF you're good at
soldering, you should be able to do it with minimal heat to the battery.
I've rebuilt more packs than I can remember. My earlier problem was - in
experimenting - I used older cells with "some" life left. After a while they
did die and had to be replaced, sooner than newer cells of course. But then
I bought new cells and have had good luck with all packs. So, it isn't
impossible! MNS

I forgot to mention one thing. I've torn apart many packs when I was
scrapping for cells in a severe shortage. I had several packs here. I took a
fine pair of dikes and cut/peel the straps off just under them from the
battery. I reuse them to do other packs. THEY ARE SHARP... BE CAREFUL.
They'll get you like a razor or paper cut. In a pinch, I also use regular
wire as a strap. Small gauge, about 18 or higher. MNS

Thanks guys. I do quite a bit of soldering but never tried doing batteries.
I couldn't imagine them being any harder than anything else, but I wasn't
sure. I suppose some people might skip the tinning process, but that is what
makes most jobs easier.
$100. plus tax sure scares me into trying a homebrew approach.
