Prius (2010-12) :: Charging A Dead 12 Volt Battery
My dad's Gen III has been sitting garaged for almost a year now, and of course the 12 volt battery is dead. Firstly, it's sitting in a one car garage, and secondly I have a Gen II so a straight jump isn't possible. I have a trickle charger that should be able to bring the 12 volt back up in 15-19 hours, but here's my question:
Maybe I'm being lazy, but I'd rather not deal with climbing in the back to release the hatch and running an extension cord so I can get the charger close enough to hook straight up to the battery..
Prius (2004-09) :: Red Triangle And VSC Warning - 12 Volt Battery Not Charging?
I've seen this a couple times but always made it home with the Red Triangle and VSC warning. A year ago, I blamed it on the OEM 12 volt battery and eventually replaced it with a Optima Yellow Top. No more problem until today. Day time driving with my Plug-in Supply 10k rechargeable conversion performing normally. City driving raining but normal Western WA conditions. Red Triangle and VSC warning. Other systems operating normal.
I knew, from previous experience that the Prius operating systems would continue to work only until I turned it off. I did turn off the Plug-in Supply controller to isolate that system and observed that the OEM traction battery was at a fairly high state of charge and the ICE was still providing the normal amount of assist to the traction battery through normal street and driving conditions.
I should have driven the 20 + miles to get home, even with the Red Triangle warning. I had done that in the past with the old OEM 12v battery. But I needed gas and went to a station and turned off the system ICE out of habit. Sure enough, the system wouldn't go back into Ready but would go from Park to Neutral. Since it was rain hard now, and I was calling my road service, I ask for a Flat Deck Tow home rather than a jump start.
As soon as I got off the tow truck I put my battery charger on the Yellow Top and it only read 11.7 volts. It's still on charge now. Now I'm wondering why the power conversion system wasn't charging the 12 volt battery or is my 1 year old Optima bad?? Or is there something about my driving conditions/plug-in conversion that is effecting the charge of this battery. I did a 2400 mile road trip to So. Calif and back to WA without any problems. Car has just 98169 miles right now. About 10k miles on the Plug-in Supply conversion.

As our Pri age, sooner or later the 12 v battery will fail and at exactly the wrong time. So perhaps preventive maintenance means replacing it just before failure. What has been the experience of other owners of 2010's as far as failure goes?

We accidentally discharged the 12 volt battery in our 2010 Prius with an interior light. By the time we noticed the car didn't have enough power to turn on. I removed the battery last night and charged it with an intelligent charger and have since reinstalled.
Will this have any long term effect on the battery? It seems these 12 volts are sensitive compared to a standard car battery. I have discharged numerous 12 volt car batteries with no major long term consquences after a recharge.
Prius (2010-12) :: Dead 12 Volt Battery After ECU Update
I got the ECU Update Friday.. Today my 12 volt battery died.(got it started after a jump)..Any correlation?? Toyota service days no. Is there any kind of a warranty on the 12 V battery? 2011 with about 40k on it seems way low for the battery to die. No changes in driving habits since ECU update either..

what is the 12v charging amperage of the gen II Inverter?
i just bought a 07 Prius with 43k
i am into ham radio and i will be installing a handfull of ham radios, including one that on high power can draw as much as 20 amps from 12v system during transmit.
all the radios in receive mode together draw about 6 amps.
im used to traditional alternator ratings of 50 70 90 and 100+ amps but upon searching this site, i have found no info about the 12v battery charging systems amperage output.
any one have specs on the 12v charging system output?
Prius (2010-12) :: Disable HV Battery Charging Or Regeneration?
2010 gen III bought Aug 2009.
Would it be possible to disable HV battery charging or regeneration (with torque pro regen coop)? This way I could use battery and ICE power when going up a long mountainous area, and end up with 30% charge at the top instead of 60%. Then on the way down I could use regen to build back up the battery.
Prius (2010-12) :: ICE Versus Charging On Depleted Battery At Low Speeds
Yesterday I was stuck in traffic and the battery eventually went down to 2 bars and the engine came on.
My question is: In stop and go traffic, if I stay in the first half (left part) of the HSI while the engine is on to recharge the battery, is the ICE turning the wheels or just charging the battery?
Prius (2010-12) :: Charging Hybrid Battery While Driving On City Roads?
How I can charge my hybrid battery while driving on city streets with an average speed of 35-45MPH. Once I get off the highway, the hybrid battery is almost full, only missing two "bricks" or "Bars." I will then accelerate very slowly only using the electric motor to drive the vehicle for the next couple of miles.
Once the battery has depleted to where it only has two bars, I will then accelerate a little faster to run the engine so it can charge the battery. But, I bring up the energy monitor and then watch the arrows.. making sure that arrows are coming out of then engine to drive the vehicle AND making sure that the electric motor is not supporting the engine.
Prius (2010-12) :: Battery Charging While Going On Downhill Especially With Braking Mode / Cruise Control On?
Curiosity question. I've noticed that on a downhill of a couple miles, especially in "braking" mode or with the cruise control on, the motor/generator and engine are used to keep the speed down and the battery gets charged to the very top quite quickly. That's good!
On a really long downhill, will the motor/generator still be used for braking and the excess electricity discarded to keep from overcharging the battery?
Prius (Gen 1) :: Car Sat Idle - 12 Volt Aux Battery Died
Well, since I had to fix the traction battery. The car I bought was a salvage vehicle that had been rebuilt.
On pesky problem was found after I'd had the car for about 4 months. I let it sit for three days. When I went to start it nothing happened. The 12 vdc Aux battery died. It tried charging it and it wouldn't charge. I bought a new aftermarket battery at WalMart and installed it. Merrily being led down the garden path I figured I'd not see that pesky problem again.
I was wrong. It continued. About the time I was going to tackle it, I moved and that took the next 4 months and the Prius sat idle when the HV Traction battery error cropped up.
This week I figured since all the carpets and shrouds were out of the trunk for the battery repair I'd look at the luggage courtesy light, it was the most obvious cause of an error. Sure enough the lamp would not shut off even though it seemed to operate correctly. It pulls up ground and turns on the light.
Prius (2004-09) :: 12 Volt Battery Drain
I started having a problem last week when my 2007 Prius was setting for two days while I was using my pickup truck. Found the 12 volt battery dead so I disconnected it and tested it with a battery load tester. And it showed it was bad. Well Ok, that figures, since it was an OEM battery and ~6-7 years old.
I have another 2007 Prius here for body repairs so I took the aftermarket (newer) battery out of it and topped the charge off in it. The battery load test indicated it was still a serviceable battery.
Put it in the car and cleared the red triangle, etc.. Everything was fine.
Since I was still going to be short one battery, I contacted Battery Systems, my shops battery dealer and ask them to drop off a new Yellow Top Optima that fits the Prius (FYI my shop price is $159.96). I would be a couple days til their deliver truck would be here and again I left the car sit for a couple days and drove my truck. On the day of the delivery, I had an appointment and drove the Prius, about 15 miles. No problem. Left it at in a street parking space for about 2 hours. Came out and all systems were dead. Nothing. Dome light was the only indication that the battery was so low that it was very dim. Head light were off and I hadn't used them while driving.
I called for road service and got a jump start and the systems came up and I was able to clear the Read Triangle when I got home by turning the car off and back on again.
The new Yellow Top Optima arrived shortly there after and I installed it. Drove the car for 6 days and this morning everything was fine when I drove to church and left it, head lites off (never had used them), came out 2 hours later and when I started the car, I got the Red Triangle and Ready but continued home. I turn it off and on again but this time I got no Ready but the Triangle and the whole sting of check light. Could only get it from park into neutral. Nothing else. Wouldn't clear.
Using my Torque Pro program, tried to read the ECU and it indicate no codes stored, Several tries, no codes or history. Called friend who has reader that will read the CAN Bus and he managed to find an odd P0503 code having to do with a speed sensor. Cleared that and the Triangle went out.
In the end I went and checked the voltage of the new battery and it was only 12.01 volts. I put the load tester on it and the condition is fine. Just the charge voltage is low.
Prius (2004-09) :: 12 Volt Battery Would Not Boot Up Car
2009 Prius 36,000. Driven at least 30 miles per day. Two months ago, 12 volt battery wouldn’t boot up car. Crazy messages on MFD like “Park on level surface and apply parking brake.” Jump started and drove car to the dealer. No problems found. Three weeks later, same problem. Again, no problems found but dealer replaced the battery. About three weeks later same problem except this time got the friendly Triangle illuminated. Drove to dealer and left car. I have an extended warranty so Im not too worried about any costs. The next morning the triangle was NOT lit and the only error code was low voltage. No interior lights on and current draw is normal when car is parked.

View 9 RepliesPrius (2004-09) :: 2005 Not Starting After Replacing 12 Volt Battery
My Prius has 150k miles on it. We didn't drive it for a few days and when we went to turn it on,it wouldn't work. We were able to jump start it a couple of times, however after that we ended up having to replace the battery. We purchased it brand new from toyota. Then, the car wouldn't do a thing (No sounds, no lights, other than the red amber power button and the flashing check engine light, which was not on before.) We ended up having two blown fuses and we replaced them today, one was for the battery.Now the lights are on, but the car still won't start. It will cost over $200 to have the car towed and I am really trying to avoid that right now. I don't know much at ALL about cars. but I'm trying.
