Depends on state of discharge. Overnight should do it or about 8-10 hours. No, you should not be able to overcharge, as the charge rate will taper off as the charge builds up. Just make sure you have the battery water up to the correct level prior to charging, and use distilled water.

Generally, it is recommend that you use a low amp charge, i.e. as low as the battery will accept, over a longer period of time. A 10-20 amp charger can charge most automotive batteries. Fully charging a completely discharged automotive battery, for example, with a 10-amp charger may take approximately 6-10 hours at a temperature of 80°F. Lower ambient temperatures require a longer charge time.
Some chargers automatically adjust the current and length of charge according to the battery's state of charge and then shut off when the battery is fully charged. If the charger requires manual adjustment for current or shut-off, check the charger's instructions to determine the proper current and length of charge based on your battery's rating.
Over charging causes accelerated corrosion of the positive plates, excessive water consumption, and in some cases, damaging temperatures within a lead acid battery. Deep cycle batteries should be charged after each discharge and/or after storage of 30 days or more. It is recommend that a deep cycle battery not be discharged below a 50% state of charge. Recharging a severely discharged battery (below 50% state of charge) can result in the battery becoming overheated or overcharged.
Hope this helps!
