I had five packs about the same age. NOT new, they had been used quite a few times. All but one are in almost perfect condition. The one had a 1v cell. I slow charged it at .1 amp until voltage got back up to 3v on that one cell. Then balance charged it at .2 amps. That one cell sits a little low and fades a little quicker, but still works well. The other four batteries are all very much functional and in good condition. So don't trash those old batteries yet!
