batteries + cold + intermittant driving

Our trucks usually all get driven every day - but over the weekend one of my guys got hurt (broken ribs + dislo shoulder - ATV wipeout) and won't be driving his truck much at all for a couple of weeks. He can drive if he has to but the doc said only if absolutely necessary - guess he could further injure himself getting in & out.

He's concerned it won't start after sitting in single digit (overnight) temps and wants someone to drive it every 2-3 days to keep the batts charged.

I told him to just throw a trickle charger on it and it'll be fine once he's healed up in a week or so. He still wants someone to come drive it - he's not convinced that letting it sit on a trickle charger is ok.

Need some ideas to convince him it'll be ok - btw he's an hour away. We offered to come get his truck and park in our nice warm shop but he had a good point - if the weather is bad he depends on his co issued truck to get around since his only other vehicle is a compact sports car. (Miata)

Temps

If the batteries and the glow plug system are in good working order, shouldnt even need the trickle charger. I have started my truck after sitting for a week in -15 temps here in MT with no problems. Maybe some DK white bottle in the fuel system just to ensure no fuel issues, ie gelling, but otherwise it shouldnt be of any worry.

He's got DK in the tank already - we add it to our 1500 gal tank on the farm that everyone fills from. (That way nobody "forgets")

He's saying when it sits 2-3 days in the cold it cranks slow but does start. He thinks waiting longer it might not start. Batts are about a year old.

Clean

Might want to take a look at his battery posts then, they might just need a good cleaning, one dirty post will get you for sure when its that cold.

When it was in the shop for an oil change a couple. Months back the battery posts looked good & were tight - we spray them with crc terminal protector to keep'm them from corroding.

Equip

Any aftermarket electronics in teh truck that could be dragging down the batteries? otherwise, the trickle charger wont hurt anything and keep things topped off for sure.

Only thing is an aftermarket brake controller but that shouldn't be drawing anything. It'll be around 10deg in the morning - I'm going to head that way to see if he needs anything guess I'll swap trucks with him. That way I'll get to check it over - I'll unplug the brake controller just to see if that makes a diff. Truck does have a visteon (ford) aftermarket cd/mp3/radio in it but that shouldn't draw any more that a stock radio.

Hmmmm

None of that should hurt anything. I would still pull the battery terminals if your going to have it in the shop, I have seen a few that looked great assembled, but when pulled off, the white corrosion falls out.

Cranked slow but started on the 1st try this morning @ 14deg. We run 15w40 year round since it rarely stays this cold for more than a few days round here. Checked out the batt connections - they're good. Told him to plug it in a few hrs before he needs to drive if it's below 20. (He's got a doc appt mon next week) - brought him some stew & biscuits....left his truck there after driving it into town to get groc & parked it closer to the house so a cord would reach - all he has to do is step out onto the porch and plug it in.
