I've used imrbatteries.com a handful of times in the past, no issues so far and my oldest set of batteries are several years old at this point.

Isn't it weird that we'll never (ever?) talk about lightnings as a potential renewable energy source ? in c/[email protected]

Lightning has a peak power of 1TW for 30 microseconds according to Wikipedia, corresponding to an energy content of about 8000 Watt-hours. That is enough to run a 100 watt conventional light bulb for 80 hours, so not actually much energy. You would need to capture about half a million lightning strikes a second if you wanted to power the world that way, for example.
