We truly appreciate your positive feedback on its accuracy, display clarity, and solar-powered design. We also value the thoughtful questions you raised about the battery system. Feedback like yours helps us review, verify, and continually improve both our products and documentation. Below, we’ve provided some clarifications regarding the points you highlighted.\u003c\/p\u003e\u003ch5\u003eSafe and Reliable\u003c\/h5\u003e\u003cp\u003eWe measured the battery voltage under two conditions—battery removed: 1.6 V, battery installed: 1.6 V. If the solar panel were charging the battery, the voltage would rise above 1.6 V. Since it stayed the same, we can confirm that solar power does not charge the battery, making alkaline batteries completely safe in this device with no risk of internal pressure, leakage, or overheating.\u003c\/p\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/cdb4a466-fab5-448a-90af-66fe87bac749.__CR0,0,800,600_PT0_SX800_V1___.jpg\\\" class=\\\"aplus-img\\\" style=\\\"max-width:100%;height:auto;display:block;margin:0!important;padding:0!important;border:0;vertical-align:top;line-height:0;font-size:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003ch5\u003eTruly Maintenance-Free\u003c\/h5\u003e\u003cp\u003eOur device is designed so that the main energy comes from solar power, with minimal battery use.\u003c\/p\u003e\u003cp\u003eThis means you don’t need to worry about charging or frequently replacing the battery.
