My GoPro no longer seems to be holding date/time. I’m assuming this is due to the motherboard battery? If so, is that replaceable? If so, what type of battery and are there online instructions? I’ve seen the Hero 3 tear down page, so I know it has a soldered on motherboard battery but even that teardown does not remove/call out the onboard battery type and removal/replacement.
Peter Yamamoto you are absolutely right and there is not a lot of information about this battery anywhere. I just checked mine and it is a 3V MS614FE battery manufactured by Seiko. Here is the datasheet DATASHEET SEARCH SITE | WWW.ALLDATASHEET.COM and most likely Mouser.com or Digikey.com will have those.
