Unless something came along for the newer "replacement" batteries, there is nothing helpful for the 600 series... not even the 600X 500 MHz and 650MHz
On the other hand, these batteries do not have the chips that limit life of the battery artificially, so you can push them to the limit. When you have what appears to be a short charge life, you can totally discharge official IBM battery, let it cool down, then recharge it. This way you can sometimes get longer life. You cannot expect to get much more than 60 to 80 minutes out of any 600 series IBM battery. If you are using a knock-off by one of the Chinese suppliers, you will not even get that. We have had very poor luck with all brands of the Chinese replacements... When they work, they seem to have half the life of an IBM labled battery. ________ There is no fun in doing nothing when you have nothing to do.
