Prius (2010-12) :: Battery Drain At Rate Of 1.1 Amps When Parked
Apr 10, 2012
I just bought a 2010 prius (26k miles..prior collision.. so no warranty) for my wife. The battery drains in just 3 days if left unused. I had Toyota install a new battery. Again 3 days left parked and battery was dead.
I locked myself in and measured the consumption. It drains at the rate of 1.1Amps when parked. That looks very high consumption. I want to measure with SKS turned off, but that's going to be tricky. I believe SKS resets when battery is reconnected.

I have a 2006 Suzuki Forenza with original battery, so it's been about 9.5 years now. Yesterday, I couldn't start the car, and it made a few rapid clicks on trying to start it. I didn't have time to deal with it so took a spare car to work. Came home to check/try the car and it had so little charge that dashboard lights, automatic door locks, etc. didn't work, the warning indicator lights that light up on turning power on barely lit up. Seems like the battery was nearly discharged. I'm attempting to have it charged with an external charger right now to check on the car later (and try to check for parasitic drain), have the battery tested, and bring the car to mechanic for a more thorough inspection (I'm not a car person).
I was just wondering though in the meantime: did I get lucky to get nearly 10 years of life out of a car's factory installed battery? and that it's likely time for a new battery regardless of whether the battery still holds charge? The car was working fine the previous day, I never had to jump start the car. Although I had trouble starting car once or twice in the past, but that just required waiting a bit and attempting to start car again - may have been warm weather related. It just failed yesterday, and I don't recall leaving headlights on or things like that. I'm just wondering had my car been parasitically draining already and just hit a critical point yesterday (slow drain before but faster drain at some point like yesterday), or can parasitic drain just happen all of a sudden like fine one day, then some drain/short the next that kills the battery.

I have a 97 mercury sable, we recently replaced the battery, and alternator but there's something draining the battery. The car was not ran for three days, and the battery was dead.

I have a 2010 Prius that I really love. In two separate incidents, I parked the car in a NYC parking garage and when it was delivered to me about 6 hours later the battery indicator only had two bars. There was no problems since the car recharged in about 15 minutes. On both occasions, I believe, the parking attendant left the key fob in the car the whole time it was parked. Is the car being drained because the key fob is in the car, or are the parking attendants doing something wrong? I can leave the car in my driveway for a few days and the battery is not as drained a sit is in 6 hours in the parking lot.

Is there some sort of battery drain when hatch is raised, even though the courtesy light has been manually turned off? Seems like I read something about this recently, and don't want to damage the 12v if it's true...

I recently parked my 2013 Prius in a concrete parking structure near LAX for 8 days. When I returned, the battery was dead - car was completely nonresponsive. AAA had to "resync" the hybrid system along with jumper cables to get me going. The technician said it was because the concrete drained the battery. I have previously left the car in underground garages for longer periods of time with no problem. Is this an urban legend?

My wife left her newer 2013 Prius "on" at work....by this I take to mean she did not hit the on/off button when leaving the car. to turn off the car I asked if it started ok, and she reported yes; however on return from the gym about 3 miles away, she says she noticed the Hybrid Battery bars going down very quickly now and the gas-engine on almost the whole time.

I recently was stuck in a traffic jam in the middle of the Mojave desert. Outside temp was about 102 and we crept along for maybe 15 minutes going no more than 5-10 mph. I had the air conditioning on. I noticed the power bars were rapidly disappearing and got worried that I would lose the battery if I didn't get moving. Needless to say, I finally was able to speed up and the bars came back. (dropped to 2 bars).

I have an 05 trailblazer with 99k 4.2 4wd. The headlights flicker sometimes at night when I let of the gas. Tonight was by far the worst. It looked like I had pulsating headlights. The dashboard lights do it as well. When it occurs the battery gauge drops several amps as well but returns to 14ish amps after things level out.

I am 150 mi from my service dealer and my 2005 W12 won't start . The dash lights go on , a/c vents open etc, but the keyless start or the key itself does nothing .
I recall that there may be a way to use the Accessory Battery to start the car, but I don't recall the routine. I don't want to have any local roadside service messing around. BTW it is the original battery and shows about 14amps.

I have a 2010 F150. When parked for a period of time, it kills the battery. It flashes the lights on and off as though the remote were locking and unlocking the doors and after a couple of weeks there is not enough juice in the battery to start the truck. Ford has been unable to find the problem, they replaced the headlight switch which did not correct the problem.

I checked my rx350 battery health and it is good. Still I am having recurrent issues when battery dies. And needs a restart. It happened many times and last one just happened this morning and I have feeling that this is related to rear hatch door...let me explain what happened:
Yesterday evening I went for grocery shopping and opened the rear hatch door using my car key remote, kept the groceries and closed the rear hatch using the button on the bottom of rear hatch door. I drove back to home and parked the vehicle in the garage. This morning I opened the rear hatch again and closed it, drove it to a house one block away, returned home and parked the car.
When I tried to start 1 hour later, the battery had already died. So, I have a feeling that opening and closing the rear hatch door 3 times caused this battery drain.

Just wondering if leaving the USB plugged in with the car is off drains the battery at all? Should I unplug it when I shut the car off or is it ok to just leave it plugged in?

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.

I've had my 2015 Prius Two for almost 6 weeks now, and so far am loving it. However, I noticed something strange today. I'm pretty sure that when I parked at work this morning, the hybrid battery was nearly full (two bars shy of full, I think). When I came back to leave work (~6 hours later) and started the car, the hybrid battery was down to only two bars (as in two bars above empty mark).

As the title states. It seems like the hatch release button is sticking due to the melting rubber. Would this cause a parasitic drain on the 12v battery?

I've just returned from a late-night walk, where I discovered I'd left on the dome (interior ceiling) light in my 20-year-old car (soon to be replaced by a Prius c Two!) about a half-hour previously. I thought: if I hadn't noticed my mistake, tomorrow morning the battery would probably be dead!
Could this happen with a Prius c? Or is there a sensor that automatically douses any interior light(s) after, say, 15 minutes?

I got a new Prius Plug-in 2012 and when the cold weather came this winter, which isn't that cold at 40F, the 12v battery seems to get discharged very often. This week, I must have jumpstarted the car twice already. The 12v battery seems to get drained when I park outside in the (not so) cold, or when I park underground for hours. I also notice that the traction battery gets filled up; it's as if the 12v battery drains into the traction battery.
(I leased a Prius 2010, not plug-in, for 3 years and this never happened even if I parked it for days in even colder weather.)

Battery was fully charged when left it at night that in the morning the battery level would be less. This happened to a friend of mine twice so far.
The first time it happened she accidentally left the lights 'on' which supposed to turn off on their own after 30sec. But in the morning she's only left with 2 bars from fully charged. And a week later it happened again but without leaving the lights 'on', from almost full charge to 3 bars of battery in the morning.
