They differ from typical batteries as they do not need frequent replacement. It is advised not to remove the secondary battery from the watch, as replacing it requires professional expertise. Attempting to install a regular silver oxide battery can lead to overheating, bursting, or ignition.

It is important to avoid exposing the watch to intense light sources or high temperatures during the charging process. Additionally, if the solar watch has not been charged for an extended period, it may become completely discharged and unable to charge.
