For owners of electric E-Z-GO vehicles, it is important to continue to service the batteries throughout prolonged winter storage. This blog post covers just a few basic but essential tips for golf car owners that addresses several common customer questions. 
For winter storage, batteries must be clean, fully charged and disconnected from any source of electrical drain.
For all vehicles, set the key switch to "OFF". For electric RXV vehicles, make sure the 'Run/Tow' switch is set to the "Run/Storage" position; if left in the "Tow" position, it will drain the batteries. For electric TXT vehicles, the "Run/Tow" switch should be in the "Tow/Maintenance/Storage" position; if left in the "Run" position it will drain the batteries. For both vehicles the 'Run/Tow' switch is located under the passenger seat. 
As with all electric vehicles, batteries must be checked and recharged at a minimum of 30 day intervals or required as needed. You do not need to have your vehicle continuously plugged in and charging over the duration of long term storage.
