i thought Fujitsu basically used Eneloop plant and tech to make their own Fujitsu (basically Eneloop in Fujitsu clothing)
while panasonic has no choice and use their own china plant to make the new range of eneloop.
i have used several brand of LSD battery eneloop, imedion, ansman, cycle energy(sony) (friend using GP Recyko, and it works the same)... and they last very well until today (out of 36pcs, only 2pcs cant retain charge). overheating for camera flash use is normal under stressful usages (long burst, high power usage, heaty environment). and all LSD are very good IF you use the
RIGHT charger. if you use those charger must charge in Pairs, aka
timer charger, normally it will damage your battery because it is unable to read the battery capacity and know its full. It will just continuous charge for 10-12 hours and overcharge it.
as long as you are using
Smart Charger, which can read the voltage, and support trickling charge (eg, 150mAh trickling charge at 1.15volt aka 80% till full) then your LSD can really really reach up to 2000 charge cycle (or even more!). The Sanyo bundle charger? i throw it out the window. It messes up my other battery capacity. I'm currently using MAHA c401fs(6 years now, still tiptop condition) C801D(3 year usage) and Notecore D4(2 year usage since start playing with 14500 & 18650 batts)
also if you plan to buy other brand then eneloop, try google around for more info on the particular brand and understand is it LSD type or not.
the issue was never with eneloop or
insert brandLSD battery, but the right charger for the job.
BTW, IKEA LADDA 2000/2450mAH rechargeable batteries is not true LSD type although the packaging wrote READY TO USE. its a false marketing. i brought them, charge 4 pcs, use 2 for my wireless keyboard, when my keyboard battery life is shorten after 6 month usage, i swap out the other pair, and guess what, 2 week life. charge all 4, and happened again on next cycle... yes, another 6 month went by... anddddd i used for my photography jobs. 200 fires and dead, while my eneloop continue to 1500 shots (my flash was set to 1/64 fulltime) so, i dont trust IKEA false marketing on LADDA made in china battery for heavy use like flash... all use as wall clock battery and remote control batt now.
