I like to use news stories and anniversaries of terror attacks, or terror possible dates (like Christmas, or 4th of July) to remind me to purchase or do something related to preparedness.
The recent stories from North Korea triggered a large purchase of the latest generation Eneloop rechargeable batteries, and some other rechargeable batteries.
I have been looking at solar chargers for small batteries. A fistfull of rechargables could do the duty of a drawer full of expendables. Do you have any experience with these or recommendations?
Eneloop doesn't make D's and I have to have many Ds, so went with the same new technology Tenergy Ds with the same low self-discharge of the Eneloops.
I don't think about the money these took to buy because they mean living well or barely living if I don't have them.
