i c. 22 miles is plenty. hummm.. hope your new battery holds up.

when your engine is running wat does your voltmeter say? 14v+?

Tip: Turn on your headlights for a little bit before cranking when it's real cold.

Amazing how Nissan has a borderline rating UNLESS you're out of warranty, then they want to sell you one of their crap batteries.

No. It gets the battery "warmed up". Gets the chemical reaction going so there is a better chance of getting a better crank.

id rather be using the starter to 'warm up' the battery if first try doesnt turn over.
honestly draining the capacity is risky business on a very cold day. you only get a few tries to start the car.

a lot of folks crank too short and kill the starter and try a re-attempt while it is better to just keep cranking it for up to 10sec or so in one shot. (i suppose it will 'warm up' the battery too while doing so)

not sure how long the cranking duration is on the Z since it's a push-start..and i dont drive the z in the winter.

At -10F mine only turned over a few more times than normal with an Optima. OP's battery sounds weak rather than dead.

I remember getting my Z in January of 2010 and everything seemed normal, but in the spring I inspected all the cells and only one was low and starting to sulfate a bit so instead of putting distilled water in I poured some extra battery acid I had from a motorcycle/lawnmower fill container into that one cell and hear it is 5 years later. This winter it started to show some weakness and I haven’t driven in a few weeks so I may put it on a 4amp charge for about 6 hours to boost it up. I plan on replacing it early this summer if it holds up.

Looks like it will crank for a while until the battery goes dead, It's like holding the key to the "on" position as long as you want.

i c. thanks for the info. but yah, that's how it should be done. one long attempt is better than a few short attempts and kill the capacity.

I have heard this before in the past. I don't buy it, but some do.
