    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 .

    Still have one good 18v XRP battery. Tried the aftermarkets and just was never happy with them. I caved in and bought a 20v battery and adapter while on sale. Been using without any issues. You do need the specific charger. I think it's Lithium vs. NiCad that requires that. Fun fact- in Europe the new batteries are still called 18v, the 20v is marketing for the US.

    Side note, I have also picked up a couple cheap Ryobi tools for occasional use. For those I have an adapter I picked up off Amazon for about $15 that lets me use my 20v Dewalt batteries in the Ryobi tools. Works great. Only thing to watch out for is if using the adapter and you drain the battery all the way it can kill it. Dewalt puts the electronics to manage the battery in the tools while others out it in the batteries.
