An update to the battery life of this pack.
If I had to estimate, I would say I could probably get over 1000 shots with this pack if the camera was used constantly.
Being Eneloop LSD, the charge is held very well obviously.
I shoot around 100 photos a night. I shoot 2 nights a week.
I probably got about 500 shots with 1/2 the time the camera being idle, and the other 1/4 in sleep mode, and 1/4 taking photos.
The LCD is on (low brightness) for about 4-5 seconds for review about 3/4 of every night.
Review because people want to see their photo afterwards.
I use it for the club and most of the time the camera is in the air idling. I take a shot between every minute so the camera barely has a time to go into sleep mode.
This should give you a rough idea of how the LSD pack lasts given my baseline of testing.
I also bought a 2000mah regular NIMH battery pack from ebay for $25. This pack says to use "genuine Sanyo cells".
Since the pack is regular NIMH, it does not hold a charge as well as the Eneloop LSD pack obviously.
I would say I can probably hit 1000 shots with the ebay pack too if the camera was used constantly. I get around 400 photos at the club before the ebay pack dies.
Again, my baseline for testing is 100 photos a night. I shoot 2 nights a week.
1/2 the time the camera being idle, and the other 1/4 in sleep mode, and 1/4 taking photos.
The LCD is on (low brightness) for about 4-5 seconds for review about 3/4 of every night. I shoot 2 nights a week.
I'm thinking of making a 2700mah pack just in case I need the camera to last an entire day.
I know a 2700mah battery pack will last a whole day if not more.
I will probably mod the ebay 2000mah pack when I'm starting to notice the battery decrease in performance.
I know I can get even MORE power from my battery packs if I can charge the whole pack at a 200mah current.
The lower the current, the more fuller charge the cells will gain. Too bad the Canon NP-E3 charger charges at 850mah and there's no aftermarket charger that charges even slower.
I wonder how good the refresh function is. All I know is that it discharges to a certain voltage, and that voltage to the charger is "completely discharged".
The lower the discharge, the more reconditioning the batteries will get.
