If it is depleted, please purchase a similar rechargeable battery and replace it. (There are variations in the depletion time of the monitor rechargeable battery.) *Regular dry cell batteries can also be used. In that case, solar charging is not required, and it will light up even indoors or in bright places. ・Due to imported goods, there may be some minor contact problems.
