I know it's not good to store any Li-Ion at or near 100%, but I decided to keep an portable charger in my bag or EDC pouch at all times. I'll rarely use it. I got it free at a trade show, so I don't care if it's toast after a while. It's only 2200mAh anyway. Basically a last resort to get some juice into my iPhone in an emergency.

I'm just wondering what kind of performance I can get out of this. After years on this forum I know we've beat this subject to death with the old batteryuniverse charts and military studies. But I'm wondering if anyone does the same and can provide real feedback.

I've stored all my Li-Ion cells after charging to 100% and have never had a problem. Some of them are many years old and still going strong.
