Warming your battery up

["J"]

How many here turn their headlights on for about 10seconds in these frigid temps to “warm the battery up” some? When I was a kid and first started driving my neighbor was a truck mechanic and told me to turn the headlights on for 10-15 seconds so the battery has a lighter initial load vs cracking a cold motor right off the bat. It seems to work, or I could just be imagining it lol.

I only do it when it hits the teens and the engine does seem to turn over a little faster.

I drive a Ford, no need for all that

It was 85°

It was 85°[emoji23]

And it’s a ford, needs every opportunity it can get. [emoji23]

Not the first time I've seen this advice. It seems contrary to what one would normally do but makes sense. I always forget to do so.

As many vehicles you have I’d be doing it all the time lol

Never heard of that one before despite spending 10 years in automotive. We sold lots of engine block heaters, trickle chargers, and diesel anti-gel during cold temps.

Yep, he went there!...rotflmao

Give it whirl and let me know what you see.

I've never heard of this either. Interesting. Sounds like it'd be a good trial for Mythbusters.

It has to do with electron speed, and the conductivity of the battery cable material -

If v t h {\displaystyle v_{th}} v_{{th}} is defined as the most probable speed, then

v t h = 2 k B T m {\displaystyle v_{th}={\sqrt {\frac {2k_{B}T}{m}}}} v_{{th}}={\sqrt {{\frac {2k_{B}T}{m}}}}.

If v t h {\displaystyle v_{th}} v_{{th}} is defined as the root mean square of the total velocity (in three dimensions), then

v t h = 3 k B T m {\displaystyle v_{th}={\sqrt {\frac {3k_{B}T}{m}}}} v_{{th}}={\sqrt {{\frac {3k_{B}T}{m}}}}.

If v t h {\displaystyle v_{th}} v_{{th}} is defined as the mean of the magnitude of the velocity of the atoms or molecules, then

v t h = 8 k B T m π {\displaystyle v_{th}={\sqrt {\frac {8k_{B}T}{m\pi }}}} v_{{th}}={\sqrt {{\frac {8k_{B}T}{m\pi }}}}.

And the end result is what?

DA FUGG?!?!???rotflmao

I see a lot of FRAC'ing and SQUIRT in there. I don't want to know what that formula is REALLY for lmao.

Ah, yeah I’m baffled as well lol

Dan you been watching too much Big Bang theory?

Does your Ford even start?

Started up just fine in 5° weather this morning, sum bitch is 15 years old.
