Should I store batteries off the tool. Currently I am storing batteries on the tool in the case provided by DeWalt.

Thanks, CTW

Doesn’t matter. Self discharge will happen on those 18v batteries regardless of where they are stored.

Lithium batteries have a very slow self discharge.
It is possible the tool would apply some small phantom load to the battery when not in use.
My Milwaukee tools have held a charge with the battery on the tool for over a year. Not sure about DeWalt.
But, if in doubt, it could not hurt to store the battery off the tool as long as nothing shorts out the connector contacts.

One thing worth mentioning is don’t store drained or nearly drained batteries for long periods of time. You may come back to a paper weight. Top them up if you don’t plan on using them for a while.
