Abstract
An electronic device powered by a solar panel and a rechargeable battery. The electronic device prevents draining of the rechargeable battery through the solar panel when the solar panel is unable to provide sufficient energy to power the electronic device. The electronic device prevents unnecessary charging and discharging of the rechargeable battery by disconnecting the rechargeable battery when the rechargeable battery is fully charged. The electronic device detects and reports a defective rechargeable battery by powering the electronic device off of the solar panel. The electronic device detects and handles brownout conditions when powered by the solar panel by re-connecting the rechargeable battery.
