The Ryobi charger is a really nice upgrade because it's new smart technology is actually kinder to the old NiCad batteries...so they will last longer too.
Uhhhh, no. The new 18V lithium charger CAN also charge all the various Ni-cad batteries. They are smart enough, as you state.
Ahhh...my mistake. I missed that feature when I had the charger. That makes it much nicer. Now you don't have to carry two chargers around. Wonder if Ridgid will come out with a twin battery model?
I am wondering that myself. Methinks that they are waiting until just before Christmas, and will probably be releasing a small kit with a twin-charger for the LI (and/or a charger that will charge all types, Ni-cad and LI, and voltages, 9.6 to 24 volts, of Ridgid batteries), maybe with 1 or 2 full size 18-volt LI batteries - probably in the 2.4 to 3.0 Ah range, and they will probably look similar to the current 24 volt LI batteries. This, after all, is what has been pictured on the sides of the MaxSelect tools' packaging for the last year, so I would bet that it's soon coming. I'm hoping that the radio (if/whenever it is being released), will also charge both types, and all voltages, too.
If they came out with a twin charger kit with a pair of 3Ah 18 volt lithium batteries, for $150-$200, I would jump on it. If they come out with a single battery/charger for that price they can count me out.
