Default 1S batery charging

I recently purchased the Heli-Max 230si quadcoptor, which includes a battery and charger. The battery is a 1S 1200mAh LiPo, and the manual recommends charging at 1.4amp. By my calculations, 1.4 amps should charge a 1200mAh LiPo in no more than 50 minutes or so (less, if the battery still has some juice in it.) Every time I charge it, the charger does not beep to indicate a full charge until 90 minuets have passed. When the charger beeps, the battery is not warm, and there is no "puffing."

Can I expect a full charge if I simply stop charging at 45 or 50 minutes?

A have a Hobbico Accu-Cycle Elite charger and a Triton EQ charger. Both are obviously intended for larger batteries. That said, could I safely use either of these chargers with the Heli-Max battery? I have ordered two more batteries, and would like to be able to charge them simultaneously without having to purchase additional chargers.

Either of your chargers can be used to charge your battery and unlike charging Nicads a Lipo, does not have to get warm to be fully charged. Most times when Lipos start showing signs of puffing something has gone wrong on the inside and they can be dangerous to use. For small capacity batteries like yours I have moved away from using Lipos and now use only Life batteries which are much more tolerant to abuse and a less likely fire hazard.

LiPos take longer because of their charge protocol (CCVC), they 'ramp up' slowly so as not to charge abruptly, build heat, etc., and ramp down similarly. I agree on the LiFe batteries, am swapping most of my Ni-xx and LiPos out in favor of them.
