Would you care to describe how the RayOVacs were used or not used
so that they'd lose that much capacity in only a couple of months?
Sitting in a camera or some other device, or sitting unused in a
drawer or battery case? Were these really RayOVac Hybrids or were
they RayOVac's standard NiMH batteries, which would be expected to
lose about 15% of their capacities in those 8 to 10 weeks?
I opened a sealed 4-pack of RayOVac Hybrids several hours ago.
They were purchased not 8 to ten weeks ago, but 8 to 10 months ago.
After operating for several hours in a radio that has an unusually
accurate battery meter when used with NiMH AA batteries, they show
the same reading now that they did when they were first put in the
radio, which indicates only slightly less than a full charge. The
Eneloops that were removed (just after checking with the battery
meter) showed that they had a smaller remaining charge, probably
about 50% left. But they had been used intermittently in the radio
since they were last charged several months ago. So far I've been
using Eneloops and Hybrids for about 12 months (IIRC) and haven't
seen any indication that there's a significant difference between
the two brands. But then they haven't been tested, only used.
