Any with 'Made in Japan' almost certainly come from the same factory. Ikea batteries are basically Eneloops in different packaging and the have pretty much the same capacity.The Panasonic Eneloop Nimh batteries have a much lower self diss-charge rate than other Nimh's, I think it's somewhere about 10% in a year, more convenient when your equipment only gets intermittent use.
'Project Farm' from youtube has had one in a solar light for about 6 years and it's almost the same capacity as new.
