Hi, I am going on vacations without my I1.
What is the recommended % of charge for 30 days storage?
Thank you in advance.

I usually store mine at about 40%. I think 30%-50% is recommended.

I charge mine until the third LED light just starts to blink (which equates to just over 50% charge)

It self discharges to around 60% so that's where I store mine at.

Around 50-65% is good for storage, also don't store batteries in the cold
