With Eneloop, it's important to ensure you're buying actual "Made in Japan" ones, and not just those that say things like "Japan Technology", "No.1 Brand in Japan" etc., which might be manufactured elsewhere, and might not have the same quality/reliability.
It's also important to buy from a reputed seller and do your due diligence, because there are a lot of fakes out there.
