Can an automatic gate opener battery be charged by a car battery charger if there is not enough sunlight for the solar panels?

Absolutely. This is acceptable as long as your charger is built for the type of battery used, and the voltage is right. AGM, flooded, GEL, Ni-Cad, and Lead Calcium are typical solar batteries. This battery charger can determine which is which.

Basics:
Think of a battery as an electricity tank.
Just like your hot water heater (a water tank) it cares not where the power comes from.
The hot water heater only requires water at the right pressure (voltage) to fill the tank, and not burst it. The rate at which the tank is filled (aka size of the hose) is irrelevant to ability to fill it up. However, the size of the incoming hose has everything to do with how long it takes to charge or discharge the tank.
How To:
Now back to your problem. Assuming your system is 12 volts. Your solar panels are one hose into your power tank at roughly 13.1 volts. The max charging rate for that system if 14.4 volts. The hose isn't as big as possible coming from the solar panels, and when there is no amps (water) coming down the wire (pipe), the battery (tank) is left under charged. To augment the power production, simply hook up any battery charger, the higher the amp rating on the charger, the faster it charges the battery.
Neat trick:
Jump start it with your automobile for 30 minutes. Drive to the gate, without shutting off the vehicle, attach the jumper cables to the battery Positive and the frame. The alternator has a rating of between 80 and 150 amps :) it can charge an 80ah battery in under an hour.

What type of charger do you need to charge 6 volt 2 mph kids motorcycle battery?
You need a 6 volt charger. When you buy a charger look for one that monitors the voltage level of the battery while it is charging and when the battery is fully charged it will turn off. Indiscriminate charging of a small battery can easily destroy it. Being left on the charger too long can boil the electrolyte out of the battery. A battery can not recover from this action and it will need to be replaced.
Can you use a 9 volt charger for a 6 volt battery?
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
Why does a cell phone charger drain a battery?
As long as the charger is connected to its power source it will take a small amount of power from that source (even if the phone is not connected to it), regardless of whether it is an AC "wall wart" charger or a cigarette lighter charger (although normally turning the car ignition off turns the cigarette lighter outlet off, so if it drains the car battery the car ignition switch may have a problem). If the phone is connected to the charger it may continue to take extra power even with the phone fully charged (I have a Tracfone that will drain my battery powerpack completely (if not connected to a charger its internal battery drains completely in less than 2 days even if I'm not using it at all -- this phone has something wrong in it). The real issue is now fast the charger is draining the battery. BTW, I am assuming above that you mean an external battery that the charger is connected to, not the internal battery of the cell phone itself (if this is the case I would say the phone is seriously defective as this would normally not be possible).
What keeps a battery charger from over charging a battery pack?
Most good battery chargers are automatic and will stop charging when the battery is fully charged. But if the charger is a manual charger it can overcharge the battery. With this type charger it is up to you to remove the charger when the battery is fully charged. Normally this is based on the amount of time the charger takes to charge the battery pack. Operators manual will list the time.
Can you leave a trickle charger on a car battery for 5 months?
Yes, that is the purpose of a trickle charger. Just make sure it is an automatic charger that comes on when needed and then stops charging when the battery is fully charged. You can leave it on a battery for years if need be.
Can you ruin a car battery by over charging?
Most definitely you can ruin it. Always charge an auto battery with an automatic charger that shuts down when the battery if fully charged.
Can you overcharge a car battery?
You bet you can. That is why it is always advisable to use an automatic charger that shuts off when the battery is fully charged. If you do not have one then charge it for a couple of hours and then remove the charger and check the voltage at the battery. A fully charged battery will read 12.6 volts. 12.4 at 75% charge, 12.2 at 50% charge, and 12 Volts at 25%. If it is not fully charged then put the charger back on a little longer.
How long do you need to charge your car battery using an automatic battery charger?
If it is an automatic charger let it charge until the charger shuts off.
When a battery is hooked up to a battery charger how do you know when a 12v battery is fully charged?
The meter on your battery charger will be in the green
How do you choose which car battery charger to buy?
Purchase an automatic battery charger of at least 10 amps output. Voltage has nothing whatsoever to do with what you choose. It is going to be a 12 volt output charger if you use it on an automobile. You want an automatic charger that will shut itself off when the battery is fully charged so you do not have to monitor the charger yourself. You can also buy a charger that can be used as a booster to jump start a car with a dead battery if you choose. The Schumacher SC-1000A battery charger is an excellent charger that will charge auto batteries and deep cycle marine batteries. It will charge at 10, 6, or 2 amps. It is fully automatic and sells for around $45.
Will a 12 volt battery be damaged if charged with a 24 volt charger?
Yes, a 12 volt battery will be damaged if charged with a 24 volt charger.
What are the difference that a battery charger overs 10 amp vs 2 amp?
The difference is the amount of energy the charger will put into the battery over a given amount of time. A 2 amp charger is great to use to keep a battery charged when it is in storage. A 10 amp is used to recharge a battery in just a few hours. Always buy an automatic charger so you will never overcharge your battery.
