If you were to take a ni-cad battery pack that's new in the factory package, but has been sitting in a store for 8 years how would that effect the battery life? I came across a store here practically giving away some of the old style Mikata 9.6v batteries (battery pack for drills, flashlight, etc) for a really good price but I wonder if the batteries are still any good after sitting on their store shelf for almost 8 years Thanks, John
Ni-cad sitting on store shelf for 8 years, is it any good?

battery university says they are garbage, and should be given away 
.
it would be hard to single out the cells re-form and cycle them, but that would be the "best" way to try and recover it, otherwise you end up only dumb charging them in series, and USEing them to cycle them, which would be a balance disaster, and because of that you couldnt really even try and do anything usefull to attempt a recovery.
Ni-cads are very durable, i have pulled out some old junk and brought it back to life after 5+ years, and it worked, but not good enough to bother using VRSES the cost of replacing them with newer better technology. higher self discharge, some white corosion crystals forming on the metal, and low capacity.
if you HAD that drill/saw or whatever that uses them, just the pack casing is worth good money, and replacing the cells in it internally with great stuff would be excellent, better than they were original.
if your going to buy it JUST to salvage the cells, i really think you would be better off buying some 1/2 decent ni-cads instead.
if it was 5$ for the pack, i think i would play with it (for 50$ worth of my time).
if i NEEDED that kind of pack, i might fork over 20$ for the case, then try (and hope) to bring it back to life. but i have been doing so well with ni-mhys i think i would still want to change the cells to ni-mhy.

pilot4x4,
Don't pay any money for these packs/cells. NiCds hold up to sitting around better than NiMH, but it's still not good for them, and 8 years is WAAAAAAY too long, especially if sitting around at room temperature.
They,
are,
junk.
Don't accept them even if they are free; they're not worth it.

I'd say go for it. I've got an old B&D cordless screwdriver I inherited from my Grandfather. It was NIB and never used. I'd estimate it to be well over 10 years old (he passed in 2001 and was sick with Altzheimer's well before that). It charges and works great, just like the day it was made.
The key may be to run them a bit to get things back in working order, but those old NiCad's probably are fine.

I'd buy it - and try it. If it holds charge as it should, rock on. If it doesn't, take advantage of makita's warranty. If you purchase it new - the warranty should apply in full that it should perform as a new unit
