Are all ETC devices solar-powered now?

Now all ETC devices are solar-powered. The ETC electronic tag equipment operates on a solar + battery mode, usually in a dormant state and only wakes up when triggered, which is very energy-efficient. It also maintains a solar charging state during normal times. More details are as follows: 1. Generally, ETC devices use lithium batteries internally and are charged by solar panels externally. Under normal use, they last about 3 years. If there are any quality issues within the 2-year warranty period, you can bring the ETC device to an ETC service point for replacement. 2. For users who do not frequently use ETC, it is recommended to charge the ETC electronic tag once every 3 months to prevent the internal battery from natural discharge affecting its usage.
