How about taking the car for a drive every two weeks?

 

OP here. Have not resolved this yet, but the above posts are the exact reason why this forum is so great. Tons of useful and interesting information. I am most appreciative. Mike

 

Exactly.

 

Road Salt and Snow. We can have slushy yucky roads from December to April, I'm not opposed to driving in poor conditions, but I won't have means of cleaning the car before re-storing it.

 

not a real problem... you only need to maintain the charge, so put a 1.5-3.0 watt charger on it and buy a 20000 mili amp power supply. Both can be bought on eBay or online reasonable. Take the power supply home to charge and/or buy 2....

 

Electric dolt here, so I'd like to ask: Do you mean buy a small trickle charger/tender, then hook it up to a power supply like those portable battery jumpers ? Then all I'd have to do is bring the power supply home maybe once a week to charge it back up?

 

The above is the Original Post from the Original Poster and Thread Starter.
The car will be indoors and driven once every two weeks.
A solar charger won't do any good indoors.
A jump box may work if the battery dies too much to start in those two weeks.
A charger powered from another battery through another charger and inverter is a gaggle.
Having a Spare Battery strapped in the boot is dangerous.

Just disconnect the battery. Deal with the window reset.
OR, look at post #3.

 

yes, tender/maintainer... you want it to keep your voltage good, not act like a 120 volt charger... the 20000 mili amp chargers, like I have, should power the tender for 2-4 weeks. Check it and see. I power a 3 watt USB fan for about 6 Continuous hours with mine.

 

It's not safe to leave a charger inside a vehicle while charging. Keeping it outside the vehicle in a public garage leaves it vulnerable to theft.

The best solution to preserve the battery of a car that won't be driven for 4 winter months, and stored in an unheated public garage where there's no access to AC power, is to remove that battery and store it in your garage at home while attached to your CTEK or other quality battery maintainer. Winter cold kills batteries, but keeping it on a maintainer will extend its life.

I know the battery is heavy and it's a PIA to R&R it. But that's a small price to pay to do it right and preserve the battery. Too bad you can't find suitable storage with AC power for a maintainer.

 

I live in the Boston area and familiar with such conditions. There are plenty of days in all those months where the streets do not have salt or snow. One rainy day and it's fine enough to drive around. I drove my XK (and drive my Aston Martin) all year round and when I traded the XK in, they thought it was garaged during the winter.
