Is it worth getting a battery charger and trying to revive it or should I just go buy a new battery? If a battery charger will work, any recommendations? The Schumacher chargers on Amazon get varying reviews for charging deep cycle batteries.
It may or it may not be able to charge your battery. That is the best answer I can give.
Most controllers have a low voltage point in the charge controller that when reached will automatically stop trying to charge the battery.
You can use your TV to put an initial charge into the TT's battery with jumper cables, to a raise the batteries voltage, and then plug into shore power or your home outlet.
Make sure that all your battery connections are clean and tight, check your negative ground connection on the frame and check the water level of the battery, to make sure it is filled.
When ever possible use the TT's charge controller for your TT's batteries, as that is what they are designed for. Deep cycle batteries unlike Automotive batteries do not like a FAST charge.
After you get a charge in the battery, use your newly installed disconnect switch to isolate the battery from the TT. Take a battery voltage reading and then let the battery sit for 4 hours. After the 4 hours, take another voltage reading. It should be close to the voltage reading that you initially took.
If the both the battery voltage readings are close, there is a good chance that it may hold a charge. If there is a big difference between the voltage readings, replace your battery.
A battery being charged should be around 14 volts (BULK) and will drop to 13.2 volts (FLOAT) when it is fully charged. A fully charged 12Volt batery is 12.6Volts. You never want to discharge your battery lower than 12VDC.
