It is my experience and opinion that one should always get a replacement battery when buying a device that he intents to use for more than a year. If not right away, then within a few months after purchase. The reason is that batteries for old devices tend to not be available. Unused lithium batteries do not degrade significantly within 2-3 years, so when the initial battery fails, you will have the replacement ready and available!
