Although this is a good way to see what the resting voltage of the 12 V battery is, and also shows if it is being charged, this has nothing to do with the Hybrid driving battery.

[@pauldub5767]

Exactly, this guy is a clown 🤡 .

[@johnhodgetts6617]

Exactly. Our Yaris hybrid battery is 400V!

[@PHIre156]

Ok good to know

[@sanchezmobilecarcaresanche7460]

This guy is a tool. At least he knows the alternator is good

[@xxycom8963]

Prius does not have an alternator. It takes traction battery’s high voltage and through an inverter/converter charges the 12V utility battery.

[@armandoazapantajr]

thank you so much for doing this. i just bought 2 cars (one for my wife and one for my myself) and this was my biggest concern. now i have a way to check.

[@nitrogang4416]

Thank you Very useful video, I just tried this in my prius! thanks again!

[@matdunip]

It is a good idea to make notes of these procedures and keep them in your glove compartment. I got in my car and drove off and notice that the digital clock and the radio presets had reset. I did not check anything out and later, when I had gotten to my destination and then gotten back in my car I had a dead battery. The cause was the 12V battery ground connector had come off completely. When I reconnected it I had to give it a jump with my little battery pack and I was off. I should have checked everything as soon as I noticed digital clock resetting. It does not just happen for no reason

[@johnhorgan5313]

This video is nothing to do with the hybrid battery. Its only checking the auxilliary 12v petrol engine battery.

[@rondhole]

Keep it in the garage if you want to safe your HV battery longer. Heat is the main problem for hybrid battery. The 12V battery last about 7-9 years in Florida without garage and the HV about 10-13 years.

Hi, I have a 2006 Toyota Prius that is not starting (getting in ready mode) but every thing else comes on. I check the battery using the diagnosis method and the volt is 12.3. the only time it starts is if I remove the two battery terminals and hold both connected to each other for few minutes and then put them back on the battery before it starts (get in ready mode).

Thx you bro for sharing this beautiful video. But is it because of the healthy alternator that bring the voltage up to 14.4 volts? Thx

[@hybrid32494]

hey buddy! These cars do not have an actual alternator. What happens is after the initial few seconds when the 12V battery starts the car's electronics, the Hybrid Drive battery kicks in and takes over, that is where you're seeing the 14+ volts come from. Not the alternator really.

[@hybrid32494]

hey buddy! these cars sometimes do have an issue where the dashboard does not illuminate. You can get it to light up by disconnecting the 12V Gel Auxiliary battery in the trunk for 10 seconds. It will reset the dash's capacitor that powers the dash on. Its a weird system, but older Priuses (including mine) does this sometimes.

My battery shows 90 to 100% in the morning, and when I start driving, no further than 2 blocks, the Battery drops to one bar. And then slowly builds back up. But lately, it started doing it right after I get off work. The battery gets down to one bar all the way home, for 42 miles. My gas mileage is bad 38mpg. I installed some cheap injectors, and my mpg went to 48mpg, but I got a check engine light. Then, after almost three months, I went back to the old injectors bc the car had some misfiring issues when the car was coming to a stop. I suspect a dripping injectors so with the old injectors, the misfire dissappear but the bad mpg came back.

[@JoseGarcia-sh6do]

Just tried this. Turned on accessory mode on car and was at 11.8v, then drove it and while I drove it, it was at a steady 13.2-3v,. I then parked and went to 13.8-13.9v. What does this mean?

[@mswarbrick77]

11.8 means its time to replace the 12 V battery.

[@Mr.Mikey.Holiday]

From my understanding every car (non hybrid) increases voltage when the vehicle is started by means of the altinator starting the 12v battery.

[@flagmichael]

In Toyota hybrids the 12V battery is charged by a DC-DC converter in the inverter assembly. That is why the battery voltage came up when the system went ready, and will eve before the engine starts. No alternator or starter on them.

Sorry, but this is not a good test of the hybrid battery because the prius 12v battery is very small (Amp hour capacity) and it only takes a few amps to push a fully charged 12v battery up to its full charge of 13.8 volts.

[@hybrid32494]

hey man, it sounds like your hybrid battery is fine, since it jumped to 13.5V after that means the extra voltage came from the hybrid drive battery. How old is your 12V aux battery at this point. They generally last upto around 5-8 years. Mine is around 7 years at this point.

My only problem with using this method is that the central display sometimes doesn't work. It will go off for months at a time (no consumption readout, no radio, etc.) and then start working for weeks or months. Dealers and specialty shops won't try to repair (it's obvious it's a faulty connection, but I realize it could be a bad solder on a chip, which would be ridiculously time consuming to find) but will only replace it at quite a hefty price. Trying to keep this car running, since I'm now retired.

[@hybrid32494]

hi Diana! I know exactly the reason why you're having intermittent DASH light problems, this is a common issue in all older prius cars. It's called the combination meter malfunction and results from a faulty capacitor in the dash cluster. Very pricey to repair. There is only one easy and reliable (but temporary fix). In the trunk you will find the regal 12V battery (not the hybrid battery). You need to disconnect a white wire that clips into the battery for 10 seconds. This will reset the car's electronics once you reconnect it and the dash will light up. Often times this happens in the cold, but it's a 100% temporary fix.

[@jafinch78]

@@dianadiehl I'm going bonkers trying to find the best video I've found detailing the change, though might be on a website the more I think about. This ones good as well, 2004-2009 Toyota Prius Repair MFD Digitizer though I need to get back to what I was working on. Have a good one.

I put in a deposit for $1000 at a dealership for a 2012 Toyota Prius. I am supposed to go pay the rest today September 15, 2022 or tomorrow. The car is being sold for $5500, the Carfax is clean but I’m just a little worried that it is over 220,000 miles. Can you advise me if that is a good buyer or not?

[@hybrid32494]

hey man! I'm glad to see you're looking for a prius. Let me give you some advice. The price is fair for a 2012 with high miles. As Long as you test drove the car and it's in good working order there is noting to be too worried about. The reality is for 5K you cannot even buy a cheap Honda Civic with 150K at this point. The prius will be way more economical and it's a much nicer car overall than any economy car you could get for under 7K. Also there are so many of them around that If you have battery issues a rebuilt pack is cheap (under 1K).

I just did this test on a car I bought yesterday (2008), battery is under 12v and the Hybrid battery is at 13.9, what would you recommend in this situation. thank you!

[@hybrid32494]

Hey buddy! I would say you most likely would need a new 12V battery soon. It really matters If you're in a state where it's pretty cold, the only time my 12V pack died was in wintertime when it was like 20 F outside. Otherwise it has never let me down. Even the close to 12V charge will start the car, but if it gets cold, then it's probably gonna be over with it for the battery..

[@danielmalloy6093]

Did you end up buying a new battery?

[@quadkrazykeith]

@@danielmalloy6093 yes, from the dealer. Car is running good still.

How do you check it with a 2013 Prius V?

[@khimissarak2514]

hi sir, my car before start up 9.6 and after started engine it goes to 13.6 ! how do you think about my 12v battery and should i have a new one?

[@hybrid32494]

HEy buddy, any voltage under 11 is low for the 12V battery. Do you notice any of the dash lights going out or any electric issues upon startup? The 12V aux battery is responsible for the first few seconds of starting the car, after that the hybrid battery takes over, thats why you see a voltage jump to 13.6 V.

[@richard7339]

hybrid32494 how many v dose hybrid battery have?

[@cawag98]

The prius doesn't actually start the engine with the auxiliary battery, unlike all other cars. The voltage of the auxiliary battery can easily be tested with a multimeter either in the fuse box (where the jumpstart point is) or in the tailgaite right area, where the battery is. Maybe, don't drive around while you're videoing showing stuff to us, it would be safer for other roaIf d users. My prius aux batttery was stuck at about 9.6 too - suggesting 1 or more of the 6 internal cells were not happy. Sometimes you can charge the battery (google videos on using a dumb charger to renew an old 12v battery) with a 'dumb' charger for a few hours to get the voltage back up, but in general, the battery's health is hurt by being unused/uncharged for a long time, which is probably how your car and mine got so low.

[@ahadqazi7750]

@@hybrid32494 so is everything ok That it jumps from 11.4 to 13.8 or 14.4?

[@Firenzaman]

FYI - The test you show only verifies the 12v Aux battery, and the vehicle's alternator. The diagnostic screen shown does not provide any feedback regarding the traction battery which should be in the region of 346v (comprising of 96 Lithium cells in series of 3.6v each).

[@hybrid32494]

hello my friend! Thank you for this great information, you're correct. This video is only intended to show the PRIUS SELF TEST diagnostic screen. It will show you the actual 12V battery levels in real time, and that is the purpose of this video. To test the hybrid (traction battery) there is no way to do that with any on-board equipment without other external equipment.

[@Madvizion]

@firenzaman the Prius does not have an alternator

[@Firenzaman]

@@Madvizion Ah, thanks for clarification. How does the aux battery get charged?

[@Madvizion]

@@Firenzaman it gets charged through the DC to DC inverter located under the hood of the vehicle.

[@allenthomas914]

So s long as we are getting the 14 when we start the car the hybrid battery is good?

[@hybrid32494]

OK, im glad you figured it out! Yes anything over 13.8 is good. My buddy has a prius and his runs perfectly and only registers about 13.8 at most.

[@allenthomas914]

@@hybrid32494 then I wonder why out pruis had The problem with the dash board lights the triangle light came up and would not start

[@DIYeverything513]

No that do not mean the hybrid battery is good. The hybrid battery is charged from another unit om the engine call a dc inverter. The procedure in this video to check the hybrid battery is 100 percent false as it only details how to check the auxiliary 12 volt battery.

[@mohamedrahman6657]

my car turns on with the red triangle and then the engine turns on but after a few seconds the engine power goes and when I press the gas the it doesn't accelerate does anyone know a solution
