850x90min=1275mah
So depends on how low the battery was to start with. Usually supplied with 50% charge.
Do you have a cell checker?
If each cell is close to 4.20, it's fully charged.

Btw, if a Lipo is hot under charging at slow rate, it's already too late!

Normal charge rate is 1C. Ie 2.2A for a 2200mah lipo. Will take 30-45 mins as the lipo is usually not discharged more than 50-75%. The charge rate slows as the battery gets full.
Under usual circumstances 2 hours on an 850mah charger should be enough for a 2200mah lipo.
Best of luck.
