i am looking for these types of lock as well, but not sure which type is more easier to attach and detach and hold stronger

those rechargable battery are very weak, fake capacity and can't last long

if want cheap and promising quality, get GP rechargeable

if dont mind paying more just for your shaver...
go for panasonic eneloop 4th generation, got two version, one is made in japan, the other one made in china,
the one selling in most local retailers like aeon big, tesco, are made in china, the old batch stock selling in US are made in japan, but all latest batch now are made in china ady.

advocado

Not Sony, its Sanyo, panasonic bought sanyo eneloop division and technology and rebrand it as panasonic eneloop on their 4th generation eneloop, other than branding, the main difference is on the increased charge cycle on the latest generation.


Yes, local one expensive about 40% and made in china


Charger, get smart charger with individual charging bay, 1 LED per cell instead of 2 cells per 1 LED
if possible avoid quick-charge charger to preserve your battery lifespan.


not only inefficient, they will damage and shorten your battery lifespan
