You may be correct, I've got two disposable and two 7day rechargeables (now
dead) that need to be re-cycled. I've also got two Energizers. The latter
is fully discharged, so therefore safe to use with micrometer.

'Performance' disposable (99p Shop) = 50.00mm
'Energizer' re-chargeable = 50.10mm
7Day Shop re-chargeable = 50.30mm

As you say, the rechargeables do seem a touch longer. Let's hope the newly
ordered 'Eneloop' are closer to 50.10 and won't strain cap on the Braun.

Further Googling also suggests that it's also the thickness that presents a
problem :-

A quick measure shows the following diameters :-

Performance disposables 13.45mm
7Day AND Energizer rechargeables = 14.25mm

There follows one glimmer of hope in bcCopenhagens quote, that Eneloops
conform closer to disposable AAs. Lets hope they mean length and thickness
:-)
