I thought they were the size of the 5ah but they’re a lot bigger! About the size of the 60v. I’m still very happy with them and they last a long time on the sawzall and circular

They work great, but they don't fit on all the Dewalt tools. These are I little to fat. I'm surprised, and a bit dismayed.

only issue we had was the 6's are also wider, snug fit in some tools and will not fit in the radio

They last much longer (both in terms of tool run time as well as overall lifespan) than the cheap chinese knock offs; but, they are dang expensive.

purchase a two pack back in SEP 2020 one of them is dead wont even take a charge

This is my fault for not researching enough. The 6.0 amp batteries do not allow my DEWALT DCL060 18V/20V MAX Cordless LED Worklight to stand upright like my 5.0 AMP battery. The 6.0 are significantly heavier then the 5.0 AMP. For what I do the 5.0 AMP do the job good enough Also - the 6 AMP battery will not fit the 18 to 20 volt battery adapter by DeWalt.

Older 6 amp batteries seam to last alot longer

Have used knock off brands of batteries that fit my DeWalt tools. The knock offs do work but the name brand always seems to perform better. Of course, they are much more expensive so the cost must be considered.

These are the real deal, they are quality DeWalt made, not the cheap knock-off stuff. I might have been able to find a little better price if I waited long enough but I couldn't wait that long.

I feel as though I paid too much, but I have not used these long enough to know.....skeptical
