Default Old NiCD batteries

Hi I have an old battery pack thats been laying around for a few years. When I put it in my car and try to run the car, it tweaks out and acts like its about to die. Maybe its not charging or something but it should charge since I used 2 different chargers and the same thing happens. Is this happening because the pack was unused for so long and lost permanent voltage and is there anything I can do about it like use a battery balancer or anything? Thanks.

Most likely sat for too long.

Hahahaha.... I used a matched Sanyo 1400 pack for my T-Maxx EZ start... Still holds a charge after 15 years....

I have around 15-20 1200-1700 packs that I should just ditch, I do wonder if they'll take a charge though....

if they are built in a side by side config you could discharge them and tray it. then charge them at 3amps that should wake them up.

Im actually expiriencing this now to.. here is what i did.. I have a ton of old packs, and im building a power base for my lathe.. im going to use a 4 cell pack to power it.. i grabbed a pack and it would not charge.. Basically i trickle charged it for a bit to forc some charge in it.. thn i dumped it and trayed it.. then charged at 4 amps and discharged it a few times.. you basically have to re train the pack to take a charge.. the pack will never haver any performance again but it could still run..

Just wanted to mention that instead of putting those old cells in the trash and having them go to a landfill (bad mojo), see if you can drop them off somewhere for recycling: http://www.rbrc.org/call2recycle/dropoff/index.php

Nicads don't like sitting around long with no use. If they sit they should be dead-shorted from tray then jumpered. All mine are in that state. If they crystalize around the positive they are junk.

As far as recyclers take them to Radio Shack they accept any and all batteries. I took them a bag-full about 6 months ago.

Ditto, on the Radio Shack answer.
I been playing wif RC cars for better than 20 years and have also tried to pump up some older cells. They may look good on a discharger but when actually trying them in a car/buggy/truck..., They will flop!
I have even bot some new ones on Ebay that charge up just fine but they will never be used in one of My vehicles, cuz they just simply SUK!
Even for just bashing, it wood be best to just git new ones. They ain't that expensive and U'll waste more time and energy trying to pump-up those older Packs.
