When is my 3PK fully charged

[ferrous]

How do I know if my 3PK is fully charged. When I bought it from charlie, the display read 9.6v. After a month of no use, I decided I better check on it and it displayed the same thing, maybe a little less. So I plugged in the charger and let it charge for about 8 hours. It now displays 11.4v.

What does that volt reading tell me? Is 11.4 too high? Is it a voltage reading? Can I over charge the battery with the stock wall charger?

Thanks

11.4 is the voltage reading from the pack.

Is that a peak detecting wall charger you are using?

I need to take a closer look at it. I'm not sure. I thought it came with the transmitter but that's wrong isn't it? Most of this stuff has to be separately purchased? i figured since charlie used the two together, it was probably fine.

Its the one that came with radio. I'm guessing no peak detection.
