Eneloop = Long time ago made by Sanyo ( Until ??), Now Made by Panasinic, which made 3 level of Eneloop.
Just FYI, Panasonic bought Sanyo a few years ago, so while the name is changed on the parent company, manufacturing may or may not have changed. Panasonic kept some Sanyo things in their product line where they felt they had a gap in offerings. Panasonic was already a battery mfr though, and may have migrated the production to one of their facilities, or rebranded their own rechargeables to take advantage of the brand equity, or . . .?
