I might have to take a second look at rechargeable. These sound like they might do some good.

My current strategy has been to avoid rechargeable. I have never been very impressed with them. Which sidesteps the whole problem of rotating them out of kits for recharging, self-discharge, potential memory, and finding myself in a tight spot with dead batteries.

I went with a combination of quality alkaline cells and lithium cells in a few critical locations. For my BOBs and kits every year I change out the alkaline that are installed and install the backup set. A new set becomes the backup.

The lithiums I have scheduled for a two year cycle but haven't had them long enough to cycle them yet. I have been told a three year cycle would be more reasonable, given their longevity, as long as the device they are in isn't defective. The time to change them is coming up in June. If they look strong I just may go to a three years rotation.

The used, but still good , batteries get used at work or in non-critical applications like the clocks and TV remotes.

Tip: Use a sharpie to mark on the battery the month/year they are installed. The manufacturers use-by dates are not very useful for batteries installed in devices.

I will have to look into low-self-discharge NiHM. thanks for the heads up.
