My sugggestion today would be to go purchase some batteries of all sizes that you may need. I know the last short one hour power outage reminded me very quickly that I was glad I had purchased the Goal Zero LED flashlights that do not need batteries. I still need to occasionally charge them so they are ready to use if and when we might need them. I decided today to “charge” my Goal Zero Solar Generator. The instructions say to re-charge every three months. We all laughed at one of the classes because we were frantically trying to “find” the flashlights and batteries. LOL. It’s good to have a reminder once in awhile. I can’t be in the dark if you know what I mean!
