How long can a Prius sit?

At some point it becomes an argument of semantics, not “be warned do not use a plain trickle charger that can overcharge/damage a battery”.

That “argument” is what I prefer to avoid wasting time on…

 

Some "dumb" trickle chargers can eventually overcharge a battery. I have the $5 Harbor Freight one. It probably wouldn't, because its output voltage is about the same as the "float" voltage recommended by the manufacturer of my AGM battery, which is also about the same as the voltage on the Prius (nominal) 12-volt system most of the time in READY mode. (That is, excluding periods of higher voltage shortly after start-up, when it's cold, when the transmission is in "N" or "P", when headlights are on, etc.)

 

A lot of vehicles won't tolerate a long-term storage with no 12 volt battery connected. You'll lose some of the programs and some of the modules on some cars. I haven't experimented with a Prius but I wouldn't do this to it if I were you.

 

You don't have anyone who can drive it for you once or twice a week
for 30 minutes or so?
That would keep both he 12v and Hibrid batteries charged up....

 

Well, perhaps you could leave it with someone you trust and have them drive it.
They could drive you to the place you go to get your truck....

 

Shocked that no one said to sell it. Used cars are going at a high price. Once you get licensed, you’ll be glad to have a gasser on Park for long time while on the road with no worries.

 

I've never been able to get mine to sit, or fetch, or roll over (thank god).

 

Same here. I don't understand why people write about their cars "sitting" for long periods. Mine just stands there waiting for me.

 

You can buy cars that don't need a driver to come to your door, park or sit by lowering itself. With a driver they can roll over or jump into a lake.
