How to replace the date/time battery in the EOS 5D.
Solution
The date/time (back-up) battery maintains the camera' s date and time. The battery' s service life is about 5 years. If the date/time is reset when the battery is replaced, replace the back-up battery with a new CR2016 lithium battery as described below.
The date/time setting will also be reset, so you must set the correct date/time.
1. Turn the <> switch to <OFF>.
2. Unscrew the battery holder screw.
Use a small Philips screwdriver.
Be careful not to lose the screw.
3. Take off the battery holder.
Push out the battery in direction 2.
4. Replace the battery in the battery holder.
Make sure the battery is in the proper +/- orientation.
5. Tighten the battery holder screw.
For the date/time battery, be sure to use a CR2016 lithium battery.
> switch to <OFF>.
