UpStart BP-110 Replacement Battery & Charger Kit for Canon EOS Rebel T7, SL3, T100 Digital Cameras - Perfect for Travel Photography & Vlogging

Before reading the fine print, I purchased their two battery deal, only to find that they would not charge within the Cannon camera. So I forked out another $10 plus tax for this charger. After the batteries were charged and installed in the camera, I found no communication between the Cannon Camera and the battery, so I have no idea how long I have on the battery. I am out the $10 bucks for the batteries since I had opened them and tossed the plastic clamshell packaging. However, I’m returning the charger since I still have the box. I keep telling myself to stop saving money only to waste money—brand name batteries from now on. They forced me to give their product one star, somehow I find that not fair.
