Bought a bunch of 9V batteries to use for my Rj45 tester but I do far I only need to use one as the battery lasts for a long time. They work as advertised and have not had any issues with it at all. Compared to some of my previous 9V Alkaline batteries, these Lithium Ion one make me feel a lot safer when using them. I hope Enegitech will make rechargeable batteries in the future, since I will definitely buy them.
