Replace battery in solar-powered garden wall lamp
Hi! I have a solar-powered garden wall lamp that uses a 18650 battery (specs in the attached photos). It stopped working properly so I suppose the battery needs to be replaced.
I have found this one https://www.nkon.nl/en/japcell-inr18650-3500mah.html but I am not sure if it will work?
Also, I'd appreciate it if someone could explain to me the meaning of having a protected/unprotected battery.
Thank you in advance for your help!
