    Hate to break it to you John, but your choice in power cells was a downgrade.

    In general, NiMH batteries cannot handle the high rate of charges or discharges (typically over 1.5-2 amps) that NiCAD batteries can.
    Also, NiMH batteries will not perform well in high rate discharge applications, typically providing only a small fraction of the rated capacity in these instances.

    NiMH batteries also have approximately twice the self-discharge rate of NiCAD batteries when in an used state.

    For example,a NiMH battery can discharge itself nearly twice as quickly as a NiCAD battery.

    When handled correctly though, NIMH batteries can be very beneficial, providing much longer run times than comparably sized and weighted NiCAD batteries.

    Typically they recommend NiMH batteries in applications that call for long duration but not a high amp load.

    I have a Dewalt hammer drill I need new batteries for. I have a ryobi 18v lithium cordless driver and drill kit that kicks ass.

    Dreams crushed. Hope destroyed. While that may all be true, I never run the drill at max torque from fully charged until it's dead. Usually it's short bursts and if I have a job that requires that I use a corded unit. The batteries I bought last multiple times longer than the OEM's. It's an older 12v unit.

    The reason I recommended Dewalt is because they are popular enough that as the unit ages the aftermarket steps up to produce replacement batteries. My Dewalt is over 13 years old and still kickin'. It has not been an easy life. There are multiple Dewalt service centers in Atlanta and lots of support nationally. Not too many Hitachi centers around.

    Fair enough. I just wanted you to be aware of the potential downsides to switching chemistry there.
    Sounds like you have it well under control and understand how to use your tools with the new cells, so good to go!

    I've got a Ryobi set with the drill and small circular saw. I've also got a reciprocating saw that uses the same batteries. I like the interchangeability between tools. The NiCad batteries have held up pretty good, probably 5-6 years or more but they're starting not lose life. I bought one of the Ryobi cordless weed eaters and it came with the large Lithium Ion battery that also fits everything else. That thing is great. I've also picked up a couple of the standard size Lithium batteries and they've got good life too.
