Time to charge an 18560 pack (with the Insight equipment)

[zespectre]

Finally back in the saddle with a new gift from my family (an Insight HC150R light) and I have a question. The first time I charged up the 18560 (3.7v) Li-ion battery pack it seemed to take about 4 hours. I ran the light to test runtime and then put the pack back in it's charger. Now I'm at about 6 hours and it's still not finished charging yet according to the charger.



Does anyone know how long the charging system for an Insight HC150R is supposed to take to charge the 18560 battery pack? The so-called documentation that came with the package is of no help at all.
