I usually love Amazon products, but hate these batteries. A pack of 36 AAA were purchased in 2015 and used in a number of items, ranging from clocks, multi-meters, IR temperature gauges, etc. Every single one of these devices that I have placed the Amazon batteries in, and left them for a couple years, has leaked causing serious damage to the product. Duracell and Energizer batteries have never leaked on me. Spend more money and get a quality battery that will not leak. Amazon should not be selling such a poor product that has caused many times the batteries original purchase price to my electronic devices.
