My husband swears by rechargeable batteries. If the world was perfect, we’d have only rechargeable batteries in our house. Until now, rechargeable batteries have been too expensive to stock all of our devices, but we’re slowly moving toward a full inventory. He claims that they are more cost-efficient in the long run. I have yet to do a cost analysis, but seeing that he uses batteries much more often than I do for all of his tools, I’m going to take his word for it.
If you didn’t think having rechargable batteries was enough, my husband is a large proponent of preparing for emergency situations such as an earthquake or riot. I guess having enough flashlights goes along with having enough power to keep them active. It probably goes without saying that we plan on being equipped if such a day of disaster comes our way.
