Hi! Just looking at the 3rd generation of Sanyo Eneloop Rechargeable HI-NH batteries that were released last year and specs seem impressive.
I have a supply of Eneloop batteries which I bought 5 years ago, at that time the specs for the batteries stated that they were low discharge and would still hold 90% of their charge after a year. The specs for the third generation have changed somewhat, they now state that the batteries will hold 70% of charge for 5 years. I've had a very good run with Sanyo Eneloop batteries and I have to report that their seems to be little if any of the old memory effect that we associate with Rechargeable cells. This means that if you have partly drained batteries, you don't have to worry about charging them up to full capacity and then experiencing limited life for the next cycle. These batteries are rated between 1800-2000MAH, certainly not the highest capacity AA Batteries on the market however its been my experience that the higher the capacity the bigger the self discharge factor. ********** Dane Trethowan Skype: grtdane12 Phone US (213) 438-9741 Phone U.K. 01245 79 0598 Phone Australia (03) 9005 8589 Mobile: +61400494862 faceTime +61400494862 Fax +61397437954 Twitter: @grtdane
