Until the charge volts reach 14v the battery is not charged fully, 2hrs at 2
amps is not enough. When the terminal volts reaches 14v and the current
drops below 1 amp the battery is very likely fully charged. Charge at
10maps.
The battery should show at least 12.8v after being disconnected for 12 hrs.
The current is the clue :-)
