Canon LP-E5 Li-ion battery packs

[fishinfool]

Aloha! I have a dslr that I don't use as much as I want to and haven't used in over a month now. I have 2 li-ion LP-E5's in the grip and 2 extra's and they are all in my camera's backpack.

Should I remove the 2 battery packs from the camera? Should I recharge them every once in a while? How often? :shrug:

Thanks guys!

Treat your camera battery packs the same way you would treat any lithium ion cells.

Keep them partially charged in a cool place for long term storage. When needed, charge them up and enjoy. Lithium ion cells have a relatively low self-discharge, so no need to top up every month.

When charging, do not leave them unattended. After the charger indicates a full charge, take them off. That's the way to be safe.

Unsolicited jibe:
After you put away the dslr, get yourself a good pocket sized point and shoot and start taking pictures again. If you put a flashlight or battery in the picture you could even post here.
End of jibe.

If you are sure you arn't going to use the battery packs for a while, place them in a ziplock bag at about 50% state of charge and put them in the refrigerator.

The state of charge isn't critical, just something between fully charged and fully depleted, the closer to the middle the better. All lithium battery degrade over time and placing them in the frig will slow that process down.

When you want to use them again later, take them out of the frig but keep them in the ziplock (especially with the high Hawaii humidity) until they reach room temperature. That way any condensation will be on the outside of the bag and not on the battery. Then, of course, charge them.

what they said ^ good stuff.

plus when asking if you should remove it from a device that is not in use, most every battery type used should be removed from a device that is not in use.
even a prismatic li-ion could expand a bit over time and get Stuck in there, or some such stupid thing that wouldnt be fun.

some camera devices will put a very small drain on thier batteries too, i dont know if this one does, but it will make keeping it at a maintained storage charge harder.

myself i would STILL leave one full ready to go when needed. but then again 2x50% charged is similar to 1 full

:bow: Thank you very much guys!

I just recharged them yesterday with the stock canon charger that came with the camera. The only way I know of discharging them to 50% would be to take hundreds of pics which I can't since I'm stuck at home. I don't want to just start clicking away at home just to deplete the battery to 50%.

I guess self-discharging is my best option.

you could set it into video mode, and run a small video capture for 30 min or so.
that is the method i use . i get 1:30 on a good battery, so i can guess about how far the actual capacity is during that type of drain.

they should not self discharge rapidly, but then again that is a good thing to know TOO, if they do discharge themselves, or have parasitic drain from the curcuit thing on the battery (even out of the camera)
if a li-ion is self-discharging as quickly as some of the other chemistries, it might be Bad.
remember when a li-ion self or not is discharged to far and kept that way, it will die too.

course stored long enough, years later they will still die :-( just because li-ion does not last forever. that is another great reason to take every care and maintance of it.

li-ion awesome weight and power ratio, is like a hot babe , a bit more maintance and eventually its all going to sag and droop anyway.

Sorry but no video on my old XSi but that's ok because I can start taking pictures of my collection of torches that I've accumulated since mid-march of this year. I've got a buddy (yes that's you Al) that's been bugging me about it for sometime now. Also using the built in flash should deplete them quicker.

Thanks again guys!

I have a Rebel XS I don't use that much. My last charge was just before Christmas and both batteries in my grip are still around 7.9V (3.95V per cell). I took maybe 300 pictures since the last recharge. I just leave them in the camera and I keep it turned off when not in use. It seems they won't discharge much in there. I also use an external flash most of the times I need one.
