Internal charge is maintained by main battery and will remain charged for a period of time when the main battery is removed.</P> Sun, 17 Dec 2023 16:33:18 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-5D-Mark-IV-Date-Battery/m-p/451453#M108968 jrhoffman75 2023-12-17T16:33:18Z Re: Date Battery https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-5D-Mark-IV-Date-Battery/m-p/451455#M108970 <P>Thank you.</P> Sun, 17 Dec 2023 16:36:23 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-5D-Mark-IV-Date-Battery/m-p/451455#M108970 clferdy50 2023-12-17T16:36:23Z
