i dun think u need to leave the camera batt in your camera for the smaller batt to retain the dates :think:you need the battery to constantly charge the smaller battery in the body to retain the dates info etc...
anyway I prefer to have a full or well charge battery in the body so whenever there's a last minute shoot I just grab my bag, put in body and some lenses and GO!
if not must wait a few hours to charge![]()
i did the reverse.. i remove the batteries from the flash but not the cam..I leave the battery in the camera but not in my flash....![]()
I leave the battery in the camera but not in my flash....![]()
I think both meant the same thing. Camera Li-ion batteries are safe to leave in the camera although it is better to remove them if you are not using it for a long time (>3 months).i did the reverse.. i remove the batteries from the flash but not the cam..
I wonder would you lose the date & time if you remove the battery from your camera over a prolong period?:think:i did the reverse.. i remove the batteries from the flash but not the cam..
depends on how long is that period..I wonder would you lose the date & time if you remove the battery from your camera over a prolong period?:think:
I wonder does the 450D have a backup battery? :think:depends on how long is that period..
generally that backup batt will use up its power, though at a very slow rate....so there is a chance the date/time will need to be set again after years of non-use. that is unless your camera has the seiko kinetic technology or some solar technology or something......:bsmilie:
