I have a ryobi combo set, 4 yrs old. Drill, sawzall, light, 5 1/4" saw. 2 years ago bought a drill/saw combo to get 2 more batteries. (1st two went bad) was same price as batteries alone. Nicad batteries.
Last year purchased a rigid drill and impact driver kit. I was in the market for an impact driver. I like this drill better, has a better chuck, love the impact driver. "Once you go impact for driving screw's, you never go back"
The rigid are lith-ion batteries. Much lighter.
All of above are 18volt.
Now, one of the ryobi batteries is not holding charge. I hate to scrap the whole set. The sawzall and circular saw are handy.
Advice? Part of me wants to go with rigid, seems to be better quality. Made by same company though.
Do nicads only last two years? With the first set, I took off charger when charged. 2cnd set, left on charger after charged. Same results.
Do lith-ions last longer? What has your experience been? Do you leave them on the charger, like troll motor battery?
