There have been several models of 0606i and the manual for the latest model, the 0606iAD doesn't say anything about a storage mode -

There is nothing about storage in AMains ad for this charger either. The 0610iNet chargers I have have a TCS mode (Terminal Capacity Selection) that allows to to select a %'age charged for storage. The later chargers use a Store Mode thaty allows fast and simple discharge to ~60% capacity for proper storage of of lipos.
You can charge your lipos to a voltage of 3.85v - thats about 65% of capacity. This is what Hyperion advises -
"Storage - Lipo should never be stored fully charged, or with less than 50% of capacity remaining. We strongly recommend Hyperion EOS chargers, as they have automatic STORE functions to insure that the packs are in the range of about 60%~70% capacity (3.78V~3.92V resting voltage per cell). After returning home for the day, simply use STORE MODE to achieve this automatically. Batteries are best stored in a cool, dry environment (2~20 °C or 37~68 °F)."
