How long will a lithium battery store? Answered
If I bought 2 rechargeable lithium polymer batteries for a cell phone, but only needed one for now, could I store the unused battery until the first battery quit charging (and was garbage)?
If the above question makes ZERO SENSE, let me try explaining it another way: Ok, you have this fancy gadget that you want to keep functioning for many years. Eventually, the battery inside won't be able to take a charge, and the battery will be obsolete and no longer sold. Would it make sense to buy extra batteries ('stock up') and store them for a time when the original battery went bunk; would the stored batteries be like brand new after many years (these batteries would have never been charged before.. they would be still originally packaged)?
Hope that actually makes sense :D
