Charging voltage this morning is up to 14.25V from 13.3 last night. This evening will be 48 hours and I'll take the SG then. Sounds though like something this small, only 300mA, will never get the voltage high enough to achieve a full charge. Still though, interesting to see what happens!
Stay with it up to your target voltage and run it for an hour or until you go .10 V above.
FWIW, last night I had a reason to make sure both my back up car jars were fully charged. Starting voltages were at 12.3 V and 12.6 V. As far as I know, these are identical model batteries but one is two years older. One battery was connected to a wheeled Exide shop charger and set at 2 amp output. The other battery was connected to the Wall wart at 500 ma rating. I unpowered both chargers this morning. The resting voltage now is 12.80 V on one and 12.81 on the other.
