i have an aging sonicare toothbrush with a slowly failing battery. i
understand there supposed to be non replaceable...but im gonna try anyway!
has any one on here had a go at doing this? im loathed to go out and buy
a
new one....cus its one gadget i wouldn't be without...but there expensive
to
replace just cus it needs a new battery.

They are probably non-replaceable because the case is sealed for
waterproofness..... and that could make it hard to get into.
Also when you replace the batteries it will be hard to seal it back up.

Waterproofness hardly matters for something that has just one or two
NiCd cells in it. Battery torches and toys work quite happily
underwater in my experience.

For a few minutes.
They will fail if left wet for days, as would be the case for trapped
moisture.
