Loose tube near starter battery

It is the vent tube from the 12V battery to allow any gases to be vented from the battery to the outside. This is to keep the gases from accumulating inside the vehicle. There should be a nipple on the battery where it attaches.

 

The nipple is hiding under the positive terminal assembly.
You should be able to push it on without having to disconnect the positive terminal.
If you can't, make sure you disconnect the negative first, and write down your
radio stations!

 

No, a lot of people put in non vented batteries and leave the tube hanging.
It’s a safety issue . Some are concerned about it and some aren’t

 

No. At least not exactly the same.

And if it is an AGM battery, the vent should not come into play except in a
catastrophic failure, like damage in an accident or a HUGE overcharge.

I personally would not worry about it if the battery is AGM.

 

Sorry, I didn't give enough information.
Look on the SIDE, UNDER the positive battery cable.
If it's not there, someone didn't tranfer it from the original battery.
It looks as though that battery is a Toyota batter.
You may have to go to Toyota and get the 90 degree angles plastic
that plugs into the battery so you can attack the hose.

I do see a plastic piece attached to the hose. So maybe it was broken off.
And the rest is in the battery. At the Toyota dealership they should be able
to show you a battery and where it goes....

 

My battery do not have the vent tit. My ne HB battery no have vent tits I threw away the rubber tubes . Well they're in the junk pile anyway so the battery was reassembled the HV one with no vent tubes My AGM battery 12 volt has no vent tip no place to put it It's just isn't there so the tube is just standing there like this car.

 

P.S. The 12 V battery in a hybrid does NOT perform starter functions like in a conventional car.
So it really is not a "starter battery".

 

Well, the car won't start without it, so...

 

We'll end up putting the word 'starter' in front of a whole lotta parts, if that's the criterion.

 

I like “ready battery “

 

There's a not-ridiculous reason for calling it the starter battery: after all, the other battery is completely disconnected when the car's off, so this is the only thing around to supply juice to the button you push when you want to use the car.

There's also a non-ridiculous reason for not calling it the starter battery: that term, to vast numbers of people, means a battery that has to supply high cranking amps to turn a starter, and if you go shopping for one of those, you'll get steered toward the exact opposite kind of battery from what works well in a Prius.

Toyota calls it the auxiliary battery, so maybe it's good to just nudge people toward that official term for consistency (but maybe not by jumping on them for saying something else).

 

Ya, that’s not gonna change

 

It's the 12 Volt Auxiliary Starter Battery!

 

It won't start without a LOT of other parts too.
Your statement is worthless.
But you really knew that already.
