PowerShot G16 internal backup battery

[Juan1974]

After 7 years of use my G16 started asking for the date/time settings each time when I power it up. I suspect it must have an internal backup battery which is depleted but cannot find any instructions on the battery replacement. Any ideas how to solve this issue? Much appreciated

Looks like it is a rechargeable battery/super-cap that is not user replaceable:

Thank you for the feedback, very helpful. I will visit my nearest Canon service center and hope they have a permanent solution to the problem.
