Is it harmful (to the life of the batteries) leaving them in the charger for
l o n g (weeks) periods of time after they have reached full charge?
Will the heat hurt them?

Dewalt and Ryobi, as you know they top off then go on trickle as needed. The heat build up, is it harmful to the life of the battery, use time and overall life?

For a batt to get damaged by heat it would have to get so hot you couldn't hold it for very long. As long as the charger has a low trickle charge then they will be fine. I'm sure that the 2 brands above chargers and fine to be left on. You can over charge a batt and thats not good but it normally only happens with timed chargers that charge a batt thats 3/4 charge for it's full charge time.

I have DeWalt and I take the batteries out as a precaution. A day or so I don't sweat it but a week? I personally would'nt.
