Replacement batteries? MiamiCuse 06-21-2008

I have a cordless drill from DeWalt that I got from a clearance sale a while
back I think for something like $129 and it included two batteries and
charger.

Now the batteries are charging up but draining very fast. I went and looked
at the new ones and they go for $70 a piece. WOW! $70 for a new
replacement 12V battery?

Is there a way to fix this instead of getting new ones?

I guess it's because I charged them before they were fully drained, or that
I left them on the charger too long after they were fully charged? or just
they go bad after two years?

Or is there a reliable online source to get good "used" or reconditioned
batteries?

Thanks,

MC

you mean NiMH.
does that include the new charger?
if you don't have a smart charger,the new cells won't last long.

Of course not, what do you want for $47? Works with my charger. Probably
most in the past 5 to 8 years.

What they say is:
NIMH -Maximum capacity packs: NiMh batteries are usually available in two
battery sizes. Small packs were 1.5 AH and large battery packs were 2.2 AH
We rebuild the small case with 2.1 AH and the larger packs are improved to
3.3 AH. Either rebuild usually adds 50% more run time.

Some batteries can be upgraded from NiCd to NiMh cells - The question is
can your charger be used with NiMh? Unless the original charger is
identified for use with NiMh, it is probably not adaptable to NiMh. The
charger may not provide an adequate charge rate to fill the larger capacity
NiMh cells. This condition is usually never noticed, since even if not
completely filled, the battery will provide much more run time that the
original NiCds.
