Great for a Multimeter
I bought this (these) for my Fluke 87 multimeters. All too often, I would go to use the meter (it has no "gas gauge" for internal battery) and the battery would be dead.I expect to have much better battery life using these in my multimeters.

Best 9 volt ever
I use this battery in a Shure Beta 58 wireless microphone. Yes you can hear the difference. This battery delivers a solid 8.6v right to end. I get about 48 hours out of it. That's 8 band practices a month, 2 hours each, for 3 months. The battery does suddenly die went it's at the end, no subtle fading out.
