losi lipo questions

[rcsnow2]

My friend is running the losi 7.4 volt lipo battery in his mini desert truck, and left it plugged in and turned on for probably 2 days. I dont have any of my stuff to check voltage with, but when we hook it up to the balancer both the cells show below the minimum voltage (3.2) so we know the cells are pretty low. we tried to hook it up to the charger supplied with the battery and the light on the charger flashes red. Does this mean that the charger is not charging the battery at all? I know there are people who have brought batterys back up from a very low voltage, but what is the best way to do it? if i hook the battery up to my MRC super brain 969 charger and set it to a very low voltage it should charge right?
I have been looking for answers all evening but have not found anything yet.
here is the battery we are trying to save:

If your lipo charger wont charge it, there is a reason. If you try to charge it with a non lipo charger you're probably gonna make fire, a really hot, toxic smoke fire too. LiPo's can't be fixed after they are run down below somewhere around 2.7 - 2.8 volts per cell.
