I purchased 3 3000 ma-hr 18v Ni-Mh batteries off ebay. You can't rebuild an old battery for $31. I've always had very good luck with them, they out last and out preform Ni-Cds and Li-ions, (Unlike Guido, I don't care to take my batteries apart, short out each cell and them charge them at a controlled rate. I use them, then I charge them. My time is too valuable to play with them.)
Well I charged all the new batteries, only took less than 5 minutes each. Usually a dead battery takes about 20-30 minutes to charge with the recommended dewalt charger. Then I decided to load test them using a dewalt circular saw. I used a green treated 4x4, new dewalt blade and had the blade depth at max, 2.25 inches. Each battery made one pass through the 4x4 and on the second pass pooped out. That's about all my dewalt Li-ion can do. I put the new batteries back on the charger. Again only about 5 minutes or less and they were charged. Put them back in saw and made pile of sawdust. It was like they need a wake up call or something. I have 6 other Ni-Mh batteries, oldest is 7 and they work great.
I bought two of these new batteries to give to my son and SIL as birthday presents. Last Christmas I gave each a dewalt 2 pk, drill, 1/4 inch impact, 2 li-ion batteries and the charger they will need for the NI-Mh batteries. Now they will have a good heavy duty battery in case Santa brings them more dewalt tools.
I've never seen a new battery act like this, have you?
