Dealing with a car parked for weeks and weeks?

Just having a brand new battery helps. I've gone up to 6 weeks so far and it starts right up. Especially during the winter months be sure to top off the gas tank to prevent condensation in the tank. I also put premium in for a little assurance.

 

Disconnect the battery it helps

 

Full tank and disconnecting the battery.

 

I know it's not what you'd expect, but do a pretrip on it, too. Make sure to unplug any electronics, like a phone charger, GPS, etc. I like the solar cigarette lighter trickle charger idea. I actually have a spare battery in my truck bed, so I don't worry about disconnecting it.

 

Although I do need to get a locking hitch pin, that tri-ball hitch was expensive. Don't want anyone deciding they need it more than me.

 

Somebody stole my pintle hook about 10 years ago even though it had a locking hitch pin.
If I'm going to park my vehicle for a long period of time someplace I would leave the hitch or pintle hook at home.

 

When I was out with my trainer (2 months) I was certain my battery would be dead upon returning home... I even bought a new one before actually getting home... #### thing turned right over (Suzuki Sx4 Sport). But I do have a battery maintainer now, just in case.

 

I don't worry about it. If the battery can't maintain. It's probably time for a new one. as for disconnecting. You cause electrical spikes which can damage the computer. Unless your vehicle is older then 1980. Some cars will even trip the air bags. Your computer also goes into not ready mode when connected back up. it takes 60 miles to reset itself. Same thing as clearing the codes.
