I have a bunch of AA batteries and a recharging gadget. They are Ni-MH 2200mAh rechargeable batteries, but as the years have elapsed they no longer take a full charge and poop-out on me.
Is there any way to 'pep-up' these batteries with the recharger? I've tried taking them out of the recharger after the light goes out and putting them right back in....the light goes on again for a while. Trying this over and over, to see if I can get them to accept a full charge....some seem to respond, but they still poop-out after just a little while....
Don't want to throw them away if they can be salvaged and made useful again. They are between two and four years old. Any suggestions??
