So I have 2 sonic toothbrushes, one powered by NiMH the other by Li-ion batteries (waterpik & philips). The base stations (with charger in them) look so convenient and just lure me to store devices on them.
I've studied the manuals and could not find whether device is designed to be kept on base station indefinitely or device should be stored off the charger until 'battery-low' signal.
So the question is: does it degrade the battery considerably if the device is stored all the time on the charger station?
Charge time for them is around 12-24 hrs. They use inductive charging method (I mean there's no port/plug you physically connect charger to, you just place device at or near charge station).
UPDATE So I've contacted customer supports of both companies, and asked is brush designed to be stored on charger and how long the battery is to serve.
...and basically they both said brush is designed to be stored on the charger. Phillips says there's 2 year warranty for the battery, Waterpik support mentioned it should last 3-5 years.
While this is a great battery life (longer then on my ihpone 5s lol) as @BillDubuque and @FakeMoustache mentioned they might serve even longer if stored off charger.
Would still be interesting to know what difference two charging strategies make on the battery life.
UPD could anyone please un-close this question? I'd love to accept answer from @BillDubuque as the man provided lots of useful info in comments, I'd like him to get his reps.
