Removing battery on shore power

If I remove the battery for the winter & stay connected to shore power, will the converter continue to try to charge?

IF your staying connected to shore power why bother removing the battery?

I am not sure as to why you want to remove your battery if you have 24/7 access to Shore-Power? Your TT has a Smart charging system that comes with it. It charges your battery when it needs it and then it keeps it topped off (FLOAT mode), when it does not need a charge. The cold weather up in Indiana will have no effect on the battery if it is FULLY charged and plugged in. Here is a diagram on how the TT's (the one in my TT) battery charge controller monitors/charges your batteries when connected to shore power.

Charging a battery in extremely cold weather can cause damage.

There are no problems with keeping a FULLY charged battery topped off at 13.2 Volts in the cold, very cold or heat with a SMART battery charge controller (like installed in today's TT's). When FULLY charged it is pretty much a voltage only thing. It will keep the battery at 13 VDC with 0 Amps, 99% of the time, other than a small amount of amperage once in a while (the battery will draw it when needed) to keep it topped off.

Oh, and you just have to check the water level every now and then.

Agreed. As long as you do not use the battery, its just fine.

charging a dead battery will cause damage but maintaining the charge will not hurt it. just think of all the cars driving down the street in cold climates their batteries are just fine.

Cars on the road are driven often and rarely are pulled down anywhere near 50% or below of full charge. So, it is not an issue.

On the other hand, RVs tend to use power on a steady basis for long periods of time. Charging a cold or hot battery in these conditions that has been pulled down to 50% or below can damage them and why some of the better battery chargers monitor battery temperatures.
