Battery storage instructions are not correct

[KD7LRJ]

On page 6, under the Storage heading it talks about fully charging the battery before long time (should probably say "long-term") storage. Since this is a Lithium-ion battery, storage at 100% charge is not ideal.

Battery University says this (from http://batteryuniversity.com/learn/article/how_to_store_batteries):
While lead acid must always be kept at full charge during storage, nickel- and lithium-based chemistries should be stored at around a 40 percent state-of-charge (SoC). This level minimizes age-related capacity loss while keeping the battery in operating condition and allowing self-discharge.

And this (from http://batteryuniversity.com/learn/article/how_to_prime_batteries):
Lithium-ion is a very clean system and does not need formatting when new, nor does it require the level of maintenance that nickel-based batteries do. The first charge is no different than the fifth or the 50th. Formatting makes little difference because the maximum capacity is available right from the beginning. Nor does a full discharge improve the capacity once faded. In most cases, a low capacity signals the end of life. A discharge/charge may be beneficial for calibrating a “smart” battery, but this service only addresses the digital part of the pack and does nothing to improve the electrochemical battery. Instructions to charge a new battery for eight hours are seen as “old school” from the nickel battery days.

Excellent feedback.

To be quite frank with you, though, I feel my heart wasn't in it for part 1 of the book. It's more or less directly copied over from the original manual from Baofeng UV-5R. The first few chapters are pretty low in quality from that standpoint. I will try to rewrite the first part and make it on par with the other two for later revisions. And when I do I'll incorporate your points on the battery sections for sure.

Thank you for actually filing an issue about it!
