never thought that it made any sense to insulate a battery box. It might be
logical to put a break between the cold ground and the batteries but otherwise
it’s a waste of time.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=4 color=black face=Calibri><span
style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:black'>They
need to be vented to clear the gas. Also the battery is so dense that it changes
temperature slowly anyway. If they are outside at -40 and undercharged you
could have problems but insulating keeps the cold out as well as the heat and
vice versa. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=4 color=black face=Calibri><span
style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:black'>We
still need to oversize the battery bank if it will be in a cold area. But if it
is getting charged regularly they will hold heat on their own, at least no
sudden swings.<o:p></o:p></span></font></p>
