Hey Guys,

I'm looking to fix the constant resetting of the date stamp on my A118C. I've posted under DIY, but I thought I'd post here too. Please take a look. Any help would be great.


Thanks.

Thanks, EGS. I'm not sure how to take the PCB out to see the other side, as that is connected to the display? I don't understand why it's this hard to replace the timekeeping battery--is it so you have to buy a new dashcam every so often?

Is there a solution to this? Would buying a GPS mount keep its time stamps accurate?

the RTC batteries normally last 4 to 5 years, GPS won't help you as you'll still lose files that don't have updated timestamps

thanh you for the thread. my cam was running this issue too. I have an B40D bought from gearbest similiar to B40 but with a rearcam tguess it is a replika or sth. I have changed its RTC battery with MS621 battery, it is 3V 5.5 mAh instead ML621 has 3V 11 mAh , I guess it does not make any problem later on we will see if there will be a problem.
