Hi all,
On recommendation from y'all, I sent several
of my worn-out power tool batteries to PrimeCell
for rebuilding.

Might be worth it to go NiMh for my cordless drills.


Do you need a new charger for NiMh then?

Nup. PrimeCell includes circuitry to match the stock charger
to the replacement pack.

As to rebuilds. Too expensive on some. My Dewalt 18V battery pack is
$117 including free shipping from Amazon for a 2 pack. That is only $21
more than a rebuld for 2, with new cases that have not been dropped
numerous times.

That's pretty good. Have you compared the two, normalizing for
capacity? PrimeCell claims to use higher capacity cells than
stock. If the PrimeCell rebuild gives you 10% longer run time,
that may tip the equation more in their favor. For some
combinations (NiCd to NiMh conversion) they claim up to 50%
longer run time. That's pretty remarkable.

And no shipping costs for me to ship them the cases.

Cost me U$13 to send them 5 packs, 2324 miles away.

If the fit in a post office one price box does not cost that much to ship.
The DeWalts are 2.4 amp hours. So close to the PrimeCell. I had a couple
of 9.6 and 14.4 rebuild a couple years ago by another vendor. Did not seem
to be any better than the originals, and the 9.6 pack is a welded case, and
it fell apart.
