Next Reading 8:42 A.M. Saturday Morning

Unfortunately I fell asleep and did not take the next photo until Saturday morning at 8:42 A.M. when the voltage still read 12.38 volts or roughly 70% state of charge. Based on my calculations the battery should still be at about 12.24-12.25 resting voltage based on 130 seconds of charging and what went into it.

Nikon D200
1s f/4.0 at 22.0mm iso100 full exif

other sizes: small medium large
