It’s not just a hot climate. Wife’s 2013 model 3 Prius with 250K miles has “lived”:its whole life in super HOT & DRY Phoenix AZ USA. Big battery is still healthy & I just finished top end ICE overhaul when major wear items were cleaned &/or replaced. Car now runs beautifully! But I want another 200K miles so am looking at your awesome battery maintenance videos. Thanks for doing them!
Great video! Corrosion CAUSES heat, plus ambient heat, hard on ANY battery. Extreme heat/cold are hard on ANY battery. I worked at a lead/acid battery mfg so I'm "old school". I believe in slow charge, so if it was MY battery, u went thru all that trouble, I could wait a couple days.😉😁🇺🇸
Yes, this is good advice, for lead-acid batteries. When you get to AGMs, they prefer a bit sturdier charge like 0.1 C, so a 100 ah battery should get 10 amps max while charging (if it wants it). The NiMH are a different animal. It is harder to tell when they are charged - the voltage stays relatively stable. The signature is more pronounced with a much stiffer charge, and 1 C is appropriate. That means these 6.5 A.H batteries are best charged at 6.5 amps. It isn't easy finding a charger that will do that.
I live in Indiana which is in the US. Indiana weather fluxuates back and forth where be in the 90 degrees Fahrenheit and the next day be 50 degrees Fahrenheit. All I have is a driveway. I don't have a garage to put my car in. I take extra steps in hot weather by open all my doors allow the inside to cool off before turn on the car. The moment I do turn on the car is to turn the ac on full blast. When in winter I don't have control of that. Plus there is no videos shows how to protect hybrid batteries from kids spilling their drinks in the back seat or dogs peeing in the back seat. I hope designers thought of this.
Hey buddy...just seen your video and subscribed...interesting and informative stuff you say on here... Just wondering.. at 7:43 mark you stated 20% of LOSS CAPACITY on that Battery. Can you tell me how you know? Do you have like a sensor, gauge or machine to determine the exact loss or battery capacity left? Thanks alot. keep up the videos.
I brought my pruis new in 2012 it has 162,000 miles when do you think my hybrid battery going go bad. Do u recommend me when it goes bad just buy a new oem from dealership because its going last another almost 200,000 miles.
I can't help but wonder how much of the corrosion on the links are due to salt air of your location. The green on the nuts indicates chlorine.That suggests it's more than just heat that causes the corrosion. Green is also oxidized copper.The car's computer reduces battery usage when the battery gets hot, controlling the temperature. I see that on my DR Prius app on Highlander Hybrid 08. That said, corrosion shouol be removed no matter what the cause.
You probably have saved me $25,000 easy. How? Any hybrid that was used in the American south will have exactly the same problem. So buying a used one must be done with great care. It’s not enough to examine the high voltage battery fan filter, you also have to check the battery itself.
Have you had any issues with heat soak? With his state of charge, does your batteries particularly in the middle heat up over a threshold and the cooling fan not working quick enough to cool it?
Hello, what is the typical symptom, when a hybrid battery (Toyota Camry) is too hot? Will the hybrid management system decrease/cut electric power output? In very hot weather (38°C/100°F) with AC off, I experienced a) the combustion engine would keep running all the time and won't turn off and b) electric driving is impossible. After parking in the shade, with AC cooling the cabin down, EV driving is/was possible again. Is this a normal safety program of the system to preserve the health of the battery or did I already destroy the battery? Car isn't showing any faults in the instrument display. I have the car since a few months. Today was first very hot day driving it. Car has never before showed aforementioned behavior.
hello every body, I am from reunion island and i have a toyota yaris hybrid 2012. since two month, I have engine light and abs light 'ON' with disconection of hybrid system.So for a long time i just reset the system with pulling out minus cable of 12 volts battery. last week i open the battery pack and found a lot of corrosion on the cell terminals. so i just clean it with water +salt+ vinegar and took the voltage. i found that the cells N° 11 ans 12 has 7.77 and 7.78 volt the others have 7.80 to 7.90 volts. So I did not change the emplacement of cells and put it back on the car. I constat that when i put my air conditioning during 10 minutes of drive, the engine + abs light comes 'ON' again with hybrid disconection again. and today i try to drive without air conditioning, no message appear and no disconection of hybrid system. do you think that its battery pack? and i also have code U0100 with U0293. thanks in advance for your responses.
Great videos. Is there a good interval do do this in colder climates? Obviously it wouldn't be every year like in the Caribbean, but in North Carolina for example, would this be good to do once every 5 years? Once every 10?
Jose, thank you so much for your channel it helps me out everyday I'm even fixing other people's braces now LOL anyways I have a question after I balance my batteries the traction battery will the check hybrid system check engine light thingy will that go away if the batteries are rebalanced and I clean the EGR thing out and cleaned out my fan I think everything should be okay but will that fix the car? Thank you
As long as they have same capacity it should be fine... for more great info you can just sign in our online HV battery training... send me a DM via our instagram page 👋😎 you will love it...
(This might make another great videoTopic) What type and model number diagnostic scanning tools are you using for these hybrid HEV vehicles. I'd like to be able to at least read, reset and clear Hybrid codes. But most cheeper $300 and less odb2 scanners wont have these abilities. Thank you.
Hello I had a question for you. Once the bad modules have been replace does the permanent code for the hybrid battery go away after driving it around for 100 miles or so? Or does it have to be eliminates by a mechanic?
Hi there, I lived in Singapore and driving a Sienta Hybrid with 1NZ-FXE. Recently I realised my fuel economy can no longer go pass 17KM/L. Did a scan on hybrid battery capacity and it shows 44.52%. May I seek your suggestions should I reconditioned or get a brand new battery? Mileage is 180k km.
Where in the Caribbean are you at brov 🤔 ? Blessings from Jamaica 🇯🇲. Currently researching the Honda HRV/Vezel hybrid. Sort of worrying about that heat phenomenon now...😟
So there is only one material better at corrosion resistance than Nickel, gold. Lol. The mirror finish is to ensure more surface area in contact. The only way to get better contact is using a foil of Indium. But indium corrodes. Do you ever add 2% nitric acid to the battery acid for cleaning copper?
You say we don’t have to clean both sides to a mirror finish, but what about the electrode that makes contact with the busbar on the other side? Doesn’t it require contact to the busbar with a mirror finish?
Can’t find sulfuric acid anywhere. Can you recommend an alternative? Also, brake cleaner doesn’t remove the black stain from the nuts. Is there something else that will work? Thx
@@hybridsolutiondiagnostics ok, got it. I used industrial strength vinegar, baking soda and 2000 grit water paper. It came out shiny but still had 5-10% of markings on it. But none of the remaining stains are on the contact part. I wish I could send you a pic. Is that ok? Also, the nuts are BLACK! Even brake cleaner won’t clean them. I’ll have to hit it 2-3x and see what happens. LoL
Can’t get sulfuric acid anywhere here in the USA unless I buy a dead $30 battery from the junk yard. Is there another way to clean the copper busbars? Also, can the sulfuric acid be removed from one of those sealed Prius batteries?
@@hybridsolutiondiagnosticssulfuric acid not available in any US parts stores. Also, nobody sells a used car battery. Highly regulated. Any other options?
Really enjoying your videos. Interesting subject. Do you think car 🚗 color may factor in to possibly degrading batteries over time. Since darker colored cars like black for example get hotter inside when sitting in the sun ☀️ as opposed to white cars which would be cooler. Would be interesting experiment.
@@hybridsolutiondiagnostics replaced my 12V battery today and I think there are two options in my case why it may swell: 1. I used the battery reset switch about 5 times (battery voltage was 9.5V at these moments). As I know, this switch just closes the circuit through the inverter to fast charge the battery. If so, there can be a very big current flow that can damage the battery even if this battery can handle this current officially. 2. One time the main battery fuse was blown (the fuse was 125A, replaced on 150A). At that time I didn't know how the battery reset switch worked (interesting thing, with the disconnected main battery if You click on battery reset the car will turn on the 12V battery but will not charge it). So the 12V battery was drained fully to 9 volts and after that battery reset even did not work. So I just connected the terminals from another 12V battery to jump-start the vehicle and I think that was a mistake because of current flow. I think, In both cases, there are no current limitations and that really can damage the battery.

It’s also dangerous because you’re dealing with high voltage
Somebody should hotwire the fan so it always blows at high...? :)
i wonder if gold plating the bus bars and nuts would provide a permanent solution for the corrosion problem
Yes indeed, but too expensive ☝️🥴🤣🤣🤣
I prefer vinegar over battery acid for corrosion cleaning & neutralization.
It safer for normal humans.
