    So I am back to this again. I really need batteries and not sure the setup I need. I want to use the 20 V ion batteries in my old 18v XRP stuff. I need the adapter and charger I realize. What is the largest amp per hr 20v battery I can use (2,3,4 etc)? Can I use my 18v (yellow) ion charger to charge the 20v ion batteries with the adapter on?

    Off topic but I buy the Chinese aftermarket 18 volt batteries for like 20 dollars or less. I’m sticking to that. I like the 18 over the new 20 personally.

    Tried them and did not have great luck. Die quicker than the XRP battery. I wish they would have lasted longer cause that wld be my go to answer.

    I just learned these will fit and work. You have to nip off a lil piece of plastic. Dewalt charger works also. 1/3 the price.

    Since I retired all those Dewalt battery drills ,sawzall etc came home with me.I think I have about a dozen batteries and three chargers .A few extra batteries must have a cell or two bad which some time I may delve into repairing but since I don't need them that might be some time . .
    I saw a thing on You Tube where a guy made an adapter to use a car battery which evidently had a high enough voltage to run the drill .Of course it wouldn't be real portable but usable .I some how can't see anybody lugging around a 40 pound battery .
