Testing new Eneloop AA batteries

I recently opened a new pack of “AA” size NiMH eneloop battery pack, based on the manufacturing date the batteries should be around 10 months old, so I thought that its a good idea to test the LSD NiMH (low self discharge batteries) claim made by Sanyo Eneloop batteries, these batteries capacity is rated at 2000 mAh when fully charged. The manufacturer claims that these LSD NiMH batteries should hold 90% of their capacity after 6 months and 85% capacity after 1 year of storage.

Reconditioning rechargeable NiMH batteries
