The batteries are presented on the site of LR44 button batteries Eunicell brand. I chose this brand especially to avoid camelion mark which is the subject of adverse criticism on amazon. What is my surprise to receive Camelion brand batteries instead of Eunicell. A reception I tested four of the batteries before using them. The tester is calibrated as follows, to replace, low, normal, hard, very hard. 4 of tested batteries: one showed strong, the other 3 showed low. They last time they will do, but I think they will not last long. 3 stars for evaluation because they are not expensive and the service has taken place, but it is a disappointment.
