• For everyday use, the toothbrush handle can be stored on the charging unit to maintain it at full power. There is no risk of overcharging the battery.
• To maintain the maximum capacity of the rechargeable battery, unplug the charging unit and discharge the batter completely every 6 months.
Straight from the manual.

I've had the same model for 3 years now. Before that I had a 7800-something.
I just put it on the charger after each use. I've never seen any decrease in capacity or drain.
I take it when I travel and bring the small charger, but I never use it, as it always has plenty of juice for the week or two I'm gone and then I put it back on the big charger when I get back.

I have the same one and just leave it on all the time. 2 or 3 years on it does not seem to make any appreciable difference in battery strength.

I have this same toothbrush, and it's made an amazing difference, switching from a manual toothbrush-teeth are whiter, and much less plaque.

Its an Oral-B Professional 5000 model.
What makes it "Professional"? Can it only be used by licensed professionals? What about us amateurs? And how long do you have to practice using it before you can turn professional?
