Battery without vent tube hole

not in an accident or overcharge situation. it depends on your risk tolerance

 

The venting plumbing is mitigation for a catastrophic failure of the battery or charging system.

Under normal circumstances it is not used.

If the battery does not have a vent port as part of its design, then I would not mess with it.

Mobility batteries are designed for installation below where the rider sits and the mobility scooter is designed and approved for indoor use, including charging indoors.

I have a similar mobility battery installed in my Gen 2 and I have the vent hose just lying by the battery uninstalled, as the battery does not have a vent port. It has been in use for coming up 5 years (fitted Apr 2014) and have had no issues. It gets externally charged regularly to keep it healthy and never had any issue with it off gassing.

Add that information to your research. Ultimately you need to decide whether it is safe or not for your situation.

 

No, I have a quick connect pigtail connected to the battery posts and is fed up to sit on top of the floor right above where the battery is located inside the trunk. It takes 2 seconds to connect the charger to the car. By externally I mean, I use an external stand alone battery charger. It is not being charged internally by the car's systems.

Every two weeks (what we call a fortnight), unless the car has been driven a lot in the days leading up. I usually check the voltage and if it is 12.7 V or above, I consider it charged enough for that fortnight.

 

I find it easier (and the voltage is what the battery is) at the pigtail. I have a small digital multimeter I use. It takes me 15 seconds to take the voltage at the pigtail.

The thing to bear in mind with using the MFD, is that you are running the car in accessory mode (at the minimum) so the voltage will be lower that reading the battery directly with everything off. There again. it depends for what you're looking.

 

Odds are you will never have an issue using a non-vented battery.

And odds are my house will never burn down. But, I do use the properly designed vented Toyota battery and I do have home fire insurance.

If you drive like a "normal driver, you don't need to worry about charging the battery.

 

I just bought a brand new battery from the Toyota dealer Saturday. It had the vent hole. Has to buy a new vent tube as someone had changed it to fit the yellow top battery that was in there.

 

Don't know if this applies in this situation, as I do not know what you paid for the battery you purchased, or why you purchased it in the first place, but, I usually find it behooves one to purchase things such as batteries (which are a pain and an expense to ship back if you have issues) locally and to use a well-respected replacement. Personally, I go for Toyota TrueStart, but any of the properly sized Exides, Interstates, etc. would also be O.K.

The issue with charging your battery is that batteries WILL (rarely) off-gas while charging.

Personally, I would not want that battery in the car and would remove it to charge it. Maybe I am being stupid, but better safe....
