HP 50G question

Alkalines will eventually leak. It's not a matter of if but when. Cool, dry storage will extend their shelf life. Storage in a refrigerator is best (but not in a freezer; freezing batteries is bad for them). Warm, humid storage will shorten shelf life. I've seen packaging of "new old stock" of calculators being sold on eBay of calculators that are several years old, where the AAA cells are visible in the bubble pack, and one or more of them have obviously leaked. The Lithium coin cell shouldn't leak. That would be extremely unusual, but would test one that's been sitting on a shelf for a long time and wouldn't trust it. If you plan on long-term storage, it should be in a cool, dry place and you should be checking on them every year. If you cannot see the batteries from outside the package, it's unfortunate.
