[[File:Duraloop.jpg|thumb|Comparison of white-top Duracell Precharged and Eneloop AA cells]]Sanyo's Eneloops are low self-discharge (LSD) NiMH [[rechargeable]] batteries. They have a nominal capacity of 2000 [[Terminology#mAh|mAh]] in the AA size and 800 mAh in AAA size. They seem to perform better than any other LSD cells ([http://www.candlepowerforums.com/vb/showthread.php?t=149804 Eneloop Self-Discharge Study] [http://candlepowerforums.com/vb/showthread.php?t=151183 Eneloop vs. Rayovac Hybrid] [http://www.candlepowerforums.com/vb/showpost.php?p=2955510&postcount=271 Eneloop vs. Imedion]). While most LSD cells retain 75-80% of their charge after a year, Eneloops can retain 85%. They are very consistent in their performance, retain their original capacity better after many cycles, and deal well with high drain applications (like a flashlight on "turbo"). Therefore if you ask on the forums what kind of battery to buy, you will be told to buy Eneloops. That said, the other brands also perform well, just not quite as well as Eneloops. If money is an issue, try the other brands, which can sometimes be purchased for as little as $1 each on a good sale. | [[File:Duraloop.jpg|thumb|Comparison of white-top Duracell Precharged and Eneloop AA cells]]Sanyo's Eneloops are low self-discharge (LSD) NiMH [[rechargeable]] batteries.

In 2010 new improved Eneloops began showing up promising 1,500 charging cycles vs. 1,000 cycles for the earlier versions. There seems to be a price premium for the newer ones right now, but unless the batteries need to be recharged on nearly a daily basis, that number of cycles seems unnecessary. | In 2010 new improved Eneloops began showing up promising 1,500 charging cycles vs. 1,000 cycles for the earlier versions. There seems to be a price premium for the newer ones right now, but unless the batteries need to be recharged on nearly a daily basis, that number of cycles seems unnecessary. The packaging clearly indicates that the new batteries can be charged 1,500 times and the batteries themselves feature a crown graphic on the label. | ||
