Oral-B says that that you need to completely discharge the battery from time to time to extend its life.
We all know this already.
Oh yeah. I actually always do this, let the battery run down completely and then recharge. I would say that it definitely has helped: my current Oral-B's (which are now finally dying) are probably at least about 10-15 years old now.
