Finally, a new post.
How many of you still have the Canon EOS 50D and still love to shoot with it? This is the very last model in the xxD line without video and still made out of a metal frame but a camera this old will start to show its quirky nature. First it was the shutter button assembly failure. Brought it to canon and it was replaced within a day.
Now, when 2 fresh batteries (BP-511A) are loaded into the battery grip they would not last a day. The top LCD would start doing the blinking low battery dance. Or in some instance a recharged BP-511A are loaded and the camera does not turn on. Sound familiar?
Do not panic. There is probably nothing wrong with the BP-511As. Nor the 50D itself. But the internal clock battery has dried up and needs replacing. The CR-2016 can be purchased in most stores that supply wrist watch batteries.
First, make sure the 50D is turned off. If a battery grip is attached, take out the BP-511As and detach the grip. Look into the 50D battery compartment and there is a little tiny plastic plate with a CR-2016 engraved on it.
Make sure the brand spanking new CR-2016 is right where you need it. Once this is removed date and clock will revert to 0. Don’t worry continuous file numbering will not reset.
Then, by pressing on the grooves with a finger slowly slide out the battery panel. The little plastic battery tray should slide out with just a little bit of friction since the slot has not been moved for years. Then remove the dead CR-2016 and put in the fresh one. + goes on the side facing the BP-511A chamber. Battery brand will not be crucial to breathing new life into the camera. Just make sure the CR-2016 are new stock.
Then slide the little tray all the way back inside the slot. Insert the BP-511A into the battery compartment and, close and lock the compartment door. Turn on the camera and the adjust date and time screen will magically appear. Set to the appropriate time zone and the old EOS 50D will have another few years to go.
That is it. Simple, easy and without problems.
