Simple question, very complex answers. It depends on what type battery you have and what kind of converter is built into your TM. I will assume for this answer that your battery is a conventional wet cell, lead acid, deep cycle, battery and that your TM converter has a three mode battery charger.

Usually the battery stays in the TM so that it can be maintained in a "float mode" condition by the TM converter charger. That means the TM stays on "shore power" all the time in storage. There are exceptions, especially if the TM converter does not have a "float" mode.

If the TM converter is not able to "float mode" charge the battery or if the TM will be stored in cold weather conditions, it is best to remove the battery to an area where it can be kept warm and on "float mode" charge.

Normally the TM battery will be somewhat charged by the tow vehicle during towing(if the TM refrigerator is on DC while towing, the battery can go dead very quickly if the tow vehicle generator is not running).

Most of the time the battery will be charged by the TM converter while on "shore power" during camping or parked where you can plug it into 120 volt AC power.

If your battery is indeed dead, it may be because the tow vehicle charging circuit or the TM battery fuses are bad.
