help needed

[ginge]

Hi I have a core rc 50 charger. I charged my batterys yesterday to take my car out a run. I ended up breaking a part so now I have to storage charge them.
The batterys are nearly fully charged 2cell 5300.
It is takin them a long time to get to 7.6 volts. Does it always take a long time I say a hour an a half. And when it came to 7.6 v it did not cut off.
If any one could help.

Thanks william
