NP-E3, How long does it last?

OK, I have not recharged the dang thing in a week. I am shooting stabilized lenses and chimping like a gorilla. Bat meter reads full. Should I expect it to drop dead instantly or will I get some warning? I have a back-up battery, so I am going to see how long this baby lasts.

So far, I don't see any problems with the battery lasting for a long shoot..Looks like Canon fixed the battery drainage problems from the 1D-MI.

You'll get plenty of warning. My wife took me to one of her art deals because she wanted some pics of the show. After about ten minutes I noticed the low-bat. The camera (D60) remained on another three hours and took another 50 some shots, and I left with low-bat still on. So I guess I don't know how long it lasts, except for a while.

Gen: That's actually the NP-E3 that the 1-series cams use. I ran mine ALL DAY on Saturday and it still read full after over 1500 shots. I had the auto-shut-off set for 30 mins so it NEVER went into sleep mode for over 8 hours. Amazing. People are reporting well over 2000 shots.

CMOS uses much less power than CCD.

Type-O, sorry.
NP-E3.
So far, I am really impressed. Wondering why I bought a back-up.

Ditto RFM's post...I ran 2 cameras last weekend for 2 days each, without changing their batteries. There were ~1000 images per camera over that period.

The MkII is mazing with htis battery.. I got about 450 shots on the 1D with it.. bitut I just got pretty much an even 1500 myself this past weekend.. never had to touch the sapre!

Now I need a 4 gig CF card to go with it!

I bought two backups!! Don't need the third at this point, but it'll make for less charging on a weekend-long shoot. I can probably shoot 4-5 days straight without ever thinking about recharging!!

One of the disadvantages of NIMH.. is they have a definate "life" as far as number of charge cycles...

To the best of my knowledge.. this "life" is NOT effected by shelf life... (at least not nearly as much as they are by charge cycles)

For instance,. the NP-E3 I got with my used 1D is so weak now that it will offer only about 75 shots in the 1D.. perhaps double in the MkII....

Granted this batt is probably about three years old.

My point is.. that I too have "too many" spares now.. and my solution is to label them.. and use only batts #1 and #2 unless I go on an extended trip.. thus batteries #1 and #2 will start to fade in a few years.. batteries #3 and #4 will be virtually brand new.



Just a thought.

That fact effects all batteries including lithium.
