WCIF Generic GoPro

Used mine everyday as a “dash cam” on my bike with no issues, charging every second or third day. Use it infrequently now but it’s probably 3 years old and the battery is still good. Are you sure you bought a genuine SJ4000? There are a lot of copies on the market, many with the SJ branding.

Yes I bought the OEM from their Guanghua store. That is their flagship store right? I went back to them and they said tough sh*t. I remember their customer service was lackidasical and it still hasn’t changed much.

Am I doing something wrong when I use/charge? I didn’t wait for the battery to run out completely, maybe 1/4 empty before I recharged it.

Perhaps they changed their battery supplier. I didn’t treat mine in any special way, various levels of charge before recharging, often empty.
