Title: Self-discharges very quickly
Review: I just tried to use two of these batteries, both brand new in packaging. The use by date is '2014'Neither battery worked in my device. When I tested the voltage, one read 3.4V and the other read 4.6V. This is supposed to be a 9V battery. Needless to say, they both went in the trash. I pulled out an old Duracell that had "Use By Mar 2012". Voltage? 9.0V.It's not worth buying a cheap Ultralast battery if it doesnt work when you need it.
Is this product review negative?
