There were several discussions in this newsgroup relating to rebuilding
batteries. As I remember, there were several favorable comments about the
feasibility of rebuilding versus buying a new battery. I surfed the net and
found several "rebuilders". Their prices were not inviting. Rebuilding could
cost more than a new battery. (Milwaukee). Anyone have first-hand info on
People seem to rave about Primecell, but the OLD Skil battery they
rebuilt for me doesn't seem all that great. I'd probably not have done
it but for the fact that Panasonic is killing me on the free drill
promotion, which is in another thread of mine.
I e-mailed my local BatteriesPlus store for a quote. Thanks for the tip.
BTW, the battery I require sells for $69-$79. A two pack for $122. However I
can buy a new drill/screwdriver with 2 batteries and a charger for $199. Go
I've bought batteries from them and was not all that satisfied. After many
many years of use, the nicads in my Norelco razor died. I brought it into a
Batteries Plus and had the batteries replaced about 2 years ago. The new
ones are already nearly dead. Barely hold a charge for 2 uses; and no I
haven't become a wolfman of late!!
I think that they are not using the best quality cells.

This is the Ni-Cad page; they supplies Panasonic batteries:
They ship next day. I rebuilt my (two) 14.4V Dewalt packs for just
under $100 CAN. One pack costs $95-$105.
Easy to do and half the price of new batteries.
Ciao for now.
Thanks for the info. I contacted our local dealer and received a quote of
$65, plus tax, plus shipping. The total cost would be at least $84. I placed
an order for a new 18 volt drill with two batteries and a charger for $199,
no tax, no shipping. A "no-brainer". BTW, our local Lowe's and Home Depot
both carry the battery for $79 plus tax of 6%.
I will try to "rebuild" my old battery pack.......after the two new packs
Thanks to everyone for your help.
I don't know where you got your battery prices, but when I went to price
batteries for my 12 year old Milwaukee cordless, they cost a fortune. I had
both my batteries rebuilt for approximately $60 each (Canadian). Works as
well as when they were new.
I believe that ensuring all the batteries used to replace the old ones
have the same charge rate, charged voltage, and dissipation rate is
enough to have good results with this. If you buy brand stuff from the
same batch you're probably good. If you're buying surplus you may have
to check this stuff with a multimeter.
My "first hand" experience is with a cheapo B&D cordless kit that uses
two (proprietary) batteries for some tools, one for others. There are
caveats with this kit that mirror your situation: Don't mix the
"silver" and the "gold" batteries, don't discharge one then use the pair
in the drill and expect to get good results, etc.
I also diddle a bit with MCU's and shtuff, and have looked into this
question myself with regard to an old laptop battery.
I've always rebuilt my own battery packs ,cheaper than having someone else
do it and easy too.The 'trick' is to replace ALL the cells NOT the 1 or 2
It is sad that you can buy a drill/charger/batteries 'package' for less than
a spare battery. Welcome to our cheap,use once,toss out,disposible society.
My city(Hamilton,Ontario) will NOT recycle consumer
electronics,steel,aluminium,etc. go figure, it ALL gos into the nearly
I am interested in your technique for connecting the individual cells. My
industrial experience predicates welding the cells using a ribbon connector.
Do you have a small welder, or are you soldering the cells together??
I will try to rebuild my "sick" battery pack. Since I ordered 2 new
batteries, I can afford to experiment with the sick one.
I've done both, but simply soldering pretinned ends of 'Solderwick'
desoldering braid to the cells has always worked for me for the past
40+years.I use a 100 W Weller iron,3/8 chisel tip same one I use for stained
I built a CD welder for a test once similar to a 'ni-cad' zapper,just more
power.I liked the iron better.
