NP-FS11 Batteries: Final Capacity

Having rebuilt the rebuilt packs, the dead cells (with arbitrary IDs) look like this:

NP-FS11 - Old Packs

NP-FS11 - Old Packs

These are the bare cells, without the protection circuit in series, so the voltage is a bit higher than the camera will see. One is completely dead and two of them appear to have about 1 A·h of capacity, but the discharge voltage evidently drops below what the camera considers acceptable.

They’d work fine driving a less fussy load, though…
