Passat (B5) :: 2003 1.8T - Battery Drain At Off
I have a 2003 Passat 1.8T. Over 8 Hrs the battery goes from 12 to 10V and the start is real sluggish. I'm going to test the load on the battery when it is just sitting there to see if there is a short somewhere. I'm wondering what the load should be from the clock and radio which draw power even when off.
It is 4+ years old so it might be just time for a new battery..... Alternator is working....14V on the battery when the engine is running...... so there is charge form the alternator.....
Passat (B5) :: 2002 - Throttle Body And Intermediate Drain On Battery
I have a 02 1.8t passat that if I don't start it for two days the battery will be totally dead. I have taken it to two places and they cant find what the draw is. The only thing that i could think of is my horn that sometimes when I am in the car it goes of randomly and my right side mirror that sometimes runs on. And my other problem is that when I drive it and I get to 3500rpm the throttle body shots of and I loose all my boost. I got a new turbo installed trying to fix the problem but still keeps happening. The only thing I could think of is that i have a stage 1 revo flash and when I took the old turbo out it may have erased the memory of the flash.

I own a 2003 BMW 5301 with the sports ,premium and 'M' package. Of late the battery drains for no apparent reason. This happened a few times 2 months ago and I had the battery and alternator replaced. This has again started happening. The car starts promptly in the morning but refuses to start in the evening when I am ready to leave work. It has to be jump started. This does not happen everyday and the BMW service folks have not been able to figure this out.
View 2 RepliesGrand AM :: 96 - Constant Drain On Battery / Car Won't Start
I have a 96 grand am that will turn on fine at first but after it warms up, it will not start and just keeps trying to turn over. I've also tested the battery with a light test and there is a constant drain on the battery, it will be completely dead overnight and when I charge my battery after starting it once, it will fully charge in about 30 minutes from red so I'm wondering if it's just not holding a charge. I'm not sure if it won't start when it's warm or if the battery just doesn't have a charge??? I took the car to autozone and the alternator passed all tests and the battery is new, the starter is 8 months old. Also the brake light stays on.

I have a parasitic drain on my battery. 4.5 amps to be exact. I've tracked it down to the CTSY fuse or Fuse 3 in the fuse block. When I pull the fuse it drops to 40 mA which is pretty normal.
What is the most likely cause of this drain since my lights seems to be working and shut off when the doors are shut? I've almost got the dash ripped apart to get at the wiring harness but hopefully I can find it before taking the whole dash out.

View 4 RepliesPrius (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.
Volvo - V70 :: Engine Misfire And Battery Drain
I’ve been having an engine misfire issue for a number of months. The dealership first changed the plugs, ignition cable kit and wiring, and that fixed it for a while. Then it came back and dealership couldn’t figure it out. They tested the O2 sensor and drove it around for a week to no avail. So I kept driving and have noticed a few trends. First the car drives better in overdrive, or when the rpms are 3,000 or above. Second when the car stalls, if I am trying to restart it immediately I have to give it some gas. Third it doesn’t mind idling in park. And fourth I’ve been having a battery drain. To solve the battery drain I’ve been charging the battery every night, and that definitely works, but I only get about 20 miles before the misfire comes back, and sometimes the misfire is just there immediately regardless. So I just replaced my alternator, and that didn’t solve the issue either. So what else could be the issue? I'm kinda at a loss and driving the car on the highway when the misfire starts is not exactly safe.

We have had a problem with our SC430 battery going dead if it sits more than a week. We have had this car for a number of years and I am tired of putting a trickle charger on it all the time to keep it from going dead!
I can not believe that Lexus does not know what the big drain is on this vehicle when it sits even for a small period of time....I went to a Lexus dealer several years ago to have a new timing belt/water pump put in it and asked how to keep my battery from going dead. They pointed over the parts counter to a motorcycle type battery charger as they answer!
A friend has a late model Mercedes hardtop convertible, they (Mercedes) solved the problem by putting two batteries in it. One is isolated for just cranking! So, before I start with a fully charged battery and pulling every fuse and disconnecting everything until I find it. What is the big battery eater?
Volvo :: Battery Drain To 8v Volts When Turn Key To On Position
My battery drains to 8v volts when I turn the key to the on position, not starting the car just turning it to the on position. I have done the key off parasitic voltage draw and there is none. This only happens when I turn the to the on position or start the car. The battery will only stay charged from a full charge to 8v or till car shuts off for less than 5 minutes. This is a huge draw! Okay it has a new battery and a new alternator, and I took battery out and did an ohms check received 14 ohms between neg and pos cable with battery out. I was told that was fine or normal. So any clues on what would cause my battery to drain so quickly? When I hook up my DVM to the battery while car is running I get 1 volt or more drop per minute only while running.

I have a 2007 LS460L. It hasn't been driven in three or four days. Today we found the car was completely dead. I had to get into the car with the manual key. The battery is one year old. The AAA person found that the light switch was set on parking lights rather than automatic. Could that have drained the battery. I thought that the lights turn off after you leave the car.
View 4 RepliesLexus LS 2007+ :: Noise Seems Repeated Every 30 Second / Battery Drain
A couple days ago the engine wouldn't start. I thought it was a dead battery (installed 5 months ago), so I brought a mechanic with a new battery. While the mechanic was working on replacing the battery, I heard some discrete noise coming out from under the hood and windshield area (driver's side). I didn't pay much attention.
Now, when I switch off the car, I can hear the noise (it's like the door's closer sound but with higher interval and it comes out about every 30 seconds). When I'm at complete stop, I hear the noise with the rpm dropping a tiny bit until the noise fades away when the rpm gets back to the normal level. The episode is repeated every 30 seconds or so. Today I felt the battery started to drain (it took longer to start the car).
LS460, '08, VSR fix done 1 year & 30K miles ago. No other problems or symptoms.

View 3 RepliesPrius (Gen 3) :: 2010 - Battery Drain While In Parking Garage
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.

View 9 RepliesSolara :: Complete Battery Drain When Don't Drive For A Week
I drive my solara pretty infrequently, but even so I am surprised by the way the battery drains to completely dead if I don't drive the thing for a week. 1 year old battery, presumably good per the folks at Schucks and its place in the price range, but if I don't actively drive the car - dead. It seems like there must be a bunch of electrical drain even when turned off, Also, when jumping (which is far too common an event) it doesn't work well unless I put the negative cord on the negative terminal instead of grounding it on the chassis like I typically do.
View 5 RepliesVolvo :: 1996 / 850 - Intermittent But Rapid Battery Drain
My 1996 Volvo 850 has a relatively new battery but every few weeks it will go completely dead. A typical situation is this: the car will start fine and we will go to a restaurant but when we come out the battery is so dead that the digital clock is off and the radio pre-sets are lost. The shop has done a lot of diagnostics and replaced the alternator but the problem persists. They have determined that the battery is fine and the current drain when the car is off is within normal specs. And, yes, they have disconnected the light in the glove box. They have done everything they can think of but because the problem is so intermittent it is proving impossible to track down.
