We've been using 7day shop rechargeable AA's in Braun Oral B
toothbrushes. There are 2 probs with the 7Dayers :-

1. They are slightly overlong (maybe half mm) and require a lot of force
to close the snap-shut cap. Is this typical of rechargeables or is it a
prob only with 7Day shop batteries? Have cracked cap one one Braun
already.

It's a problem of substandard batteries. None of mine have ever had
this problem.


2. They don't last very long - maybe 2 weeks. They can last 12 months in
a wall clock but struggle with high drain stuff.
The perfect answer is Duracell but these are not cheap. I've tried
Googling for an alternative but you get pages of Amazon spam.

Eneloop Pro NiMH have pretty high energy densities. I've had some but
not long enough to given an honest opinion.

Somewhere there's a survey of AA batteries. Ikea came top IIRC. Maybe
their rechargeables are good too
