I use a lot of batteries in my business primarily for remote sensors, and for test equipment. I use roughly 100+ AAAs and 50 AA alkaline batteries a year, plus about 2 dozen CR123A Lithium batteries. I have been using Tenergy exclusivly for my batteries since about 2020. I have found them to last at least a little longer than other brands, and I have yet to find one that is leaking, as I do with some other brands,, and their prices are very competative.
