These Hybrio / Ultralast 800mAh AAA ULSD (ultra low self discharge) batteries will retain their charge for MUCH longer, when stored, than the high capacity/high drain batteries i.e.- 850-1000mAh
Ultralast claims that after 6 months of storage the battery will retain 90% of their capacity - since this is really new NiMH technology we will see if this is really true but if they are only half right, this is really exciting!
