For emergencies.
When you need that extra battery and you don't want to run out and buy more I suggest these battery adapters for use. I have dozens of rechargeable batteries, AA size, sitting here sometimes for weeks not getting use to their potential. Now I know many out there will suggest that you just go out and buy the proper size battery for the job. I also recommend that but, when you need a battery in a pinch when you're all out of the proper size and you have these AA batteries on hand why not use them.<br /><br />Granted the size matters works here also, you will not get a lot of time out of these batteries using them and products that require C size, and D size batteries, but you will get some use out of them for a temporary period. It might get you through a few hours use of a flashlight or some other light-duty object instead of running down the street to buy batteries when you have something available.
