Battery failing

I have a solar security camera which is about 6 months old and today it is advising me that it’s down to 26%. The other solar camera I have is fully charged so it’s not a problem with light.
A code is on the app P3-17 which I can’t find what it means.
I don’t know if the battery is failing or the panel is not charging. It doesn’t get much use so my thoughts are towards a failed battery.

Hi @user300633. This is a low-battery indicator. I would suggest charging your battery to full capacity. Also, ensure that your Solar Panel is clean and getting at least 4 hours of sunlight per day.
