Warm and Fuzzy when Cold
So my truck won't catch cold this winter and future winters,
I am installing a couple 80 watt Battery wraps along with the coolant heater that comes on the truck.
Then there's a thermostat that will activate them at temps below 35 deg.
I have an idea that I wanted to get some feedback, I was thinking of installing a fender well battery tender rated at just over an amp. it's really for a boat or tractor used for storage but I thought since this device is so small, it might tickle the voltage while the wraps heat the battery casings.
Wadda ya think? good, bad, ugly? personally I don't think the trickle charger is going to do much of anything for 2 massive 1000 CCA batteries, but with freezing temps they really dip into their reserves to crank this tank over in the morning.

i also have 2 of the Battery wraps the block heater and a oil pan heater to keep my truck warm and they all plug in to a timmer that turns on before i go to work. also use 5-40 syn oil, and stanidine in the fuel. it may sound like i going a little over board but the weather system that is going through here right now its 25 below and wind chill of 45 below

Is this something you guys would suggest for a little less extreme weather on a V10? I live in SoCal, but at 6200 ft level. I've seen the winter get down to 17 degrees and 20-30's is pretty common, though, not for months at a time like other places. I was figuring on replacing the current battery with an Optima so I don't want to Kill that thing. $$

Helomech if your truck wont start in those high temps LOL then you have a more serious problem. The only real reason to add a heater in your area would be to shorten the warm-up time.

The one I have is a 1.5A automatic float type. I have another one but it's not made to be mounted inboard, it's rated at 2A or 6A and not auto anything.
So if a 800mA would work on a single, then maybe a 1.5 would work for these two under the hood?

Yes I think a 1.5 would do the two battery setup. If my single battery is pretty low it takes my .8 amp 1 to 2 days to go to float mode. These little charger/maintainers are not fast but they work very well at maintaining your battery. I keep a .8 on my corvette 24/7 except if I unplug it to drive it. Never a problem. If a late model vette sets for a month or longer they say they usually won't start. I don't know as I never have let mine sit over about 2 weeks. They being the wizards on corvette forum.com.
