Don't forget to watch Tools & Stuff video with codes on the new Forge battery: [ Ссылка ]

If you want to send me codes, please use the following example format:
AU 2024-03-22 12Ah J52BDCAF 2019-10-17 0101 365 120 512
[country] [test date] [battery type] [first 8-digits of serial #] [manufacture date] [1st code] [2nd] [3rd] [4th]

There are diagnostic codes in some M18 batteries (roughly, before mid-2015 and after mid-2021). You can see them by holding the button down for a few seconds. This video reverse engineers some of the code, but more data is needed. It is discovered that M18 batteries have a really bad charge counter (you would have to try to make one that's worse).
