LitFuse, I've purchased the AA,AAA and some 123 case holders for my regular alkaline and nimh batteries for home and car. I have purchased maybe 9 in total and highly recommend them. They are much better in my opinion than the lexan carriers being sold in manufacturers announcements for almost the same price for (one!) battery carrier. I've also purchased a lot of the type of holders that Hawkhkg11 showed but those were cheaply made and weren't very good in my opinion and some didn't last but a few openings and closings. I am currently storing all of those that I purchased with nothing in them. My only suggestion in purchasing the battery holders from inanycase is buy all that you anticipate needing so you only have to pay ONE shipping charge, I wound up ordering twice from them and that increases the cost per holder.
