Used in lecture meetings etc. I am purchasing the reliability of the stamina battery to drive the 800 MHz B band wireless microphone for 2.5 hours. Of course the price is cheap and there is nothing to come.
I saw the goods that arrived, but they are not in the bag and bundled with other goods while being naked. The inside of the package is blank due to leakage. Did not not notice it at the time of shipment? When was the alkaline battery manufactured in the first place? I am disappointed
