Yet another 'DS3231 does not retain time' question.

We used the MH marked modules in a product by removing the diode to prevent charging as suggested in several online posts to resolve the problem of the module losing time. The product were recalled from field after they lost time after a few days of operation. All the deployed units developed the problem. Battery was ok after the recall, so its not a battery issue.

I dont have access to any other modules than the ones marked MH, are they fakes and not worth the trouble?

Thanks and Regards,

Probably not.
