    I read somewhere that you can prolong Battery Life by leaving the lid off of
    devices, so heat can escape. Is this true and how much can they be prolonged if
    so?

    No matter what kind of battery you are talking about (as you failed to
    mention), this is totally STUPID and IGNORANT.

    Hi, you're right, they're called block heaters. They heat the engine
    block, not the battery at all, though some people also buy battery
    warmers, which looks like some type of heating pad that wraps around
    the battery. Do they work? beats me, only ones I've seen usually had
    the cords chewed off by the engine fan.

    The block heaters, as they are known, do not go into the dipstick tube
    though, they'd never fit even if you did want to sacrifice your tube.
    They replace one of the blocks "frost plugs", (known differently
    elsewhere)..and the heating element sits inside the blocks water
    jacket, which warms the oil and allows the engine to turn over.

    30 minutes on the coldest days are all it takes. You can even put one
    in each frost plug hole and parallel them. If that's not enough to
    start it your battery is weak and needs checking /replacing, those
    heating pads are junk.

    Cheers

    I grew up in Minnesota. My brother is a rock musician, so has to go
    out at all hours, in all kinds of weather. He used to light a pie-tin
    full of charcoal, and when it got "ready," slide it under the engine
    and leave it there for a while - I guess 10 to 30 minutes would be
    enough.

    I don't know if that's a Darwin "mediocre mention" or anything, but
    thought it might be of interest to one or two weirdos out there. ;-)

    Cheers!

    Cicuit racers often light a tray of methanol under the block to warm
    things up. Not very bright in my opinion.
