color=#0000ff size=2>Well, here in Montana, when winter starts (usually
November) we add insulation to the battery box (in an unheated shop or
garage--where many of our customer's batteries lurk, and mine also), and we
remove it in March/April. Temps from summer to winter may vary from a
high of 105 degrees F to a low of forty below zero. It's not a big deal to
add insulation as needed. Just seems like common
sense.</FONT></SPAN></DIV>

<DIV></DIV>HI Dana,
<DIV><BR></DIV>
<DIV>I'm curious about why you differentiate sealed vs flooded batteries?</DIV>
<DIV><BR></DIV>

mentioned batteries are an electrochemical unit that requires, like us, a
