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.

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.

Q. Can anyone suggest an alterative disposable brand please - of reasonably
good quality. TIA.

2 weeks between charges is plenty.

With alkaline batteries, you pay for advertising. All brands except Evolta came out at 1.9-2.2Ah per AA cell in tests. Evolta yielded about 1.5Ah. This test series was at 200mA load. But I see no sense using alkaline if you can use NiMH.

I have found GP Branded alkaline to be vastly inferior to others...
