Status: offline 		I have a Slo-V and a couple of the 8.4 volt 600mHA batteries for it. With no load the battery shows 8.84 volts but with even a slight load it is in the 2 volts or less range. The batteries sat for a long period of time with out being charged and so I am guess they are dead I was just wondering if there is anything I might be able to try to get some life back in them.

Just in case these are some last resort ideas.

Dead short them, c/10 charge them a few times with cycling, impulse, reflex or reverse pulse or burp charge them. You can also punish them by using very hiogh rate. None of these ideas are good , but as a last resort? You don't have much to lose.
