Car batteries...
    #27064719 - 11/30/20 02:02 PM (3 years, 1 month ago)

I'm trying to decide if I need a new battery or if I need to get it charged fully.

Lights work. Radio works, windows work. The car wont turn over..

So. I . Jumped. It!

The car started up almost instantly so I drove it around a bit, came back, parked it, and killed it.

Seconds later I tried starting it up again and got nothing but some lousy lights and the crappy radio.

Frustrated and a bit buzzed, I grabbed my handy dandy multi meter and checked my posts.

11.2 with the battery off... I know I need more of a 12.whatever the fuck so 11 is bad.

What I'm wondering is if a jump and a long sit would help or should I take it in and let it sit over night or do I need a new battery?

I'm hopin' for door number 1...

I had car battery issues recently and decided to buy an actual charger instead of just jumping mine. I jumped it a couple times but it would always get to a point where the engine wouldn't turn over after a couple days of use. I charged it to full and haven't had any issues since. This was 2 weeks ago.

YMMV but, maybe worth buying a $25 - $30 charger :shrug:

edit:
Sounds like maybe your jumper is also a charger, if thats the case definitely try charging that thing to full.

when you jump it, make sure you drive for a decent chunk of time (hit the freeway for 40 mins or something)

if you have to jump it even after charging it, you probably need a new battery. places like autozone will do free battery testing. just bring it in, and they will tell you if its good or not

Go to autozone or whatever and have then run a battery and alternator test. If u can start it and run it for a while on a charged battery its a bad alternator as your alternator isn't charging the battery to replace the charge lost running the car. If u cant get it started on a jump its likely a bad starter. If it's like clicking and shit could be ur connections or bad battery. Just go get it tested they give u a print off that tells u exactly whats wrong.

Its lit like the simplest thing u could have go wrong with ur car and its super common if you dont have a brand new car. A simple do it urself repair on most vehicles. Its also getting cold out and thats when ull notice your battery isn't what it used to be.

First check and clean connections especially at the battery, rarely at alternator. You describe the classic corroded battery terminal problem.

''I know I need more of a 12.whatever the fuck so 11 is bad.''
You really need closer to 14 than 12.

If cleaning terminals doesn't get it, either the alternator or battery has an issue. Getting the battery tested is easiest.
Most Autozone type places can test it in the parking lot if they're not busy. Otherwise pull it in the parking lot if it tests bad replace it while you're there. Be prepared to wait or have a ride.

If the battery tests good, it's the alternator.

They say you must drive a car 15 minutes at over 30 mph just to recharge what it used to start it. To recharge a low battery it's like  an hour on the highway to get it fully charged.

A corroded battery cable with a weak connection can quickly burn up an alternator or battery or both.

If your headlights don't seem bright, it's probably the alternator.

Almost all (maybe all) batteries have a date of manufacture and a rated longevity printed on the battery somewhere. Check to see how old your battery is and how long it is expected to last. If it is getting close to the end of its anticipated serviceable life go grab another one at Costco.

Also, this is the time of the year that batteries fail if you are living in a region that is getting into late fall/early winter. It would be a coincidence if your alternator failed right at the time of year that the cold is stressing your old/dead battery.

Heat actually kills batteries, cold just reduced cold crank voltage.  End result can be the smae, a car that won't start.

Hmm.. well... Let me start off by saying if the antichrist needed a vehicle it would be a dodge..

Why? Why would I need to remove a tire just to get to the battery?

I'll pull it tomorrow and get it tested. I'm hoping an overnight charge will do the trick because I really don't feel like changing out an alternator. 10.00 says I'll have to drop the transmission just to get to the alternator.

Thanks for all the replies.. I honestly didn't think I'd get any..

Do the battery before the alternator.

No need for changing shit just for changing shit. If the alternator is bad you'll know for sure after the new battery.

Check the basics as suggested:
-Bad corrosion on terminals or faulty wiring (clean/fix if needed)
-Alternator issue (Multimeter should show 13V+ when car is running)

Otherwise seems like maybe straight-forward junk battery?
-Again check the date of manufacture as suggested

A battery may run lights+radio but under real load like cranking the engine, that's when it counts, and dying batteries do not have the CCA (cold cranking amps) to turn the engine correctly any longer.

You want to have a good reliable battery for peace of mind and so on, as what use is the vehicle if you can not start it when desired, and how willing are you to spend time fiddling with jump-starting the car.. Go with a good brand, reliable battery with warranty.

Battery is probably done. 11v for a 12v battery is straight dead.

12.7 at rest is a fully charged LAB. Car running should read 13 or so.

Take it out, take it to autozone and they'll test it for free. If it's bad, use it
as a core exchange and get a new battery.

Wow man this is nuts.

I was literally at the mehanic today for this exact problem. Here is what happened to me:

-my alternator was broke and it killed my battery
- i needed a new battey and alternator
- cost me $650 CAD

It sounds like the exact same thing that happened to me.

Replace yur battery, if you arent at the right wattage when u check it then you need a new alternator. My suggested wattage is 80w and before they fixed the alternator it was pumping 40w. They told me the car would still run for a couplr weeks but if i didnt change the alternator my new battery would die very soon.

Its a hard bullet to bite and set me back a ways but just get it fixed and you will be on the road again.

I truly sympathize with your situation, sucks man...

I should add:

- i decided to take my car in because my car woul start with a boost but as soon as i shut it off it wouldnt atary again.
- the audible sensor that tells you that yur light is left on when yu turn your car off stopped workimg so i killed my batery several times before this.
-it seemed that each time i boosted it, it took longer to charge.

Either you need a new batery, or a new alternator, or both. Shitty buzz dude.

When I needed a new battery my car would not do anything when I turned the key. No lights no noise no nothing. Other than a window not rolling back up there were no signs that the battery was dying. I was stranded in a parking lot and had to call towing.

How long have you had your current battery? They usually need to be changed every 5 years.

Last night I was able to jump it, but had to be somewhere so I pulled it all the way up and let it sit for awhile. It prob sat running for a good hour while I was gone. Once I got back, I killed the ignition, let it sit for a minute (like last time) and cranked it. Started up!

Cool.

Went about my biz nas, my biz nas. Stay the fuck out my biz nas! Cause it's mine I'm mine.

Heh heh... Ludacris was and will always be dope.

But, yeah. It started up last night no problem. This morning will be the ultimate test though. Here in a bit I'm going to head out in the blistering cold and try and start it up after it's been sitting all night.

I still kinda wanna get it checked at O'Riley's.

Here’s my recent battery woes. My wife’s car was acting a little funky, but she was still able to run around town. Occasionally the radio would turn off momentarily, otherwise everything seemed okay. I figured it was an issue with the radio wiring. This went on for about a week. Then one day the car wouldn’t start. So I charged the battery, tested it, everything seemed fine. She drove around for another week. Then one day she’s at the gas station and the car wouldn’t start again. She gets a jump and managed to get home. So I pulled the battery and took it in. It was still under warranty so I got a free one. The car has been running fine ever since.

Long story short, batteries do some funny things some times. The symptoms aren’t always the same or necessarily consistent.

I had replaced the alternator about a year before when the car stopped dead conveniently in my driveway. So I was hoping it wasn’t that. The battery issue was actually about 4 months ago now, the car has been running fine since.

Usually if your battery is nearly dead, your radio and lights will totally dim out when you turn the ignition.

Bad connection to the radio. Once the car is running, power comes from the alternator

The battery was likely intermittently shorting internally. They have a lead lattice inside and what will happen is part of the lattice breaks and then connects two lattices together creating an internal short. Between the alternator and the correctly functioning parts of the battery the car would still run, but the amperage must have been dropping low enough for the radio to shut off occasionally. It's likely the radio is just more sensitive to voltage or amperage drops than other components.

It threw me for a loop at the time. The first time the battery was dead, I couldn't figure out why or how. I figured my wife left her lights on or something. Once the radio thing happened, and then when it died at the gas station, I knew something else was up.

The engine is internal combustion. The battery is just to supply the initial
shock to ignite fuel then it just sits there and gets charged by the alternator.

The alternator powers the electrical shit in your car while running

I'd say based on that comment alone you are well out of your depth on this one, koods.

Just about every single modern car, post like 1990, will need at least 10v (some sensors are 5v) to operate various sensors required trigger the ignition sequence as well as the fuel injection sequence. This is why it's very hard to push start a modern car, because you have to generate enough alternator voltage to bring these sensors as well as the ecu online.

Lots of motors can run without a battery, but they need a magneto type ignition, and usually carburetors.

Anything that is fuel inject will at a minimum have to run a fuel pump and actuate those injectors. Now you could use capacitors instead of a battery, it has been done before, but either way you are storing voltage on board.

It cranked over this morning! I still want to take it in and get it tested.

I'm starting to think a light stayed on and drained the battery.

I'd say based on that comment alone you are well out of your depth on this one, koods.

Just about every single modern car, post like 1990, will need at least 10v (some sensors are 5v) to operate various sensors required trigger the ignition sequence as well as the fuel injection sequence. This is why it's very hard to push start a modern car, because you have to generate enough alternator voltage to bring these sensors as well as the ecu online.

Popped the clutch 😒

It was a 1982 manual transmission

Sometimes I’d just get a couple people to push it. It was really easy to get it started

When the alternator died, I would hit it with a hammer to get it working again

1982. What did I say about cars newer than 1990? Oh yeah!

Modern cars generally need like 1200 RPM to trigger the ignition, that's hard to do by pushing a car. Manual transmission of course are going away quickly, most don't even know how to operate one.

The brushes were stuck in the alternator, by whacking it they would move up close and make contact on the slip rings. I actually had a window AC unit that would do that. You could hear it turn on, but the compressor never started. I cut a hole in the side of the enclosure and would hit the compressor motor with a hammer and it would fire right up. My wife loves to tell that story. This was in our first apartment together.

Got it tested. The shop said it was bad. He had me turn it on in order to check my alternator and starter too. Apparently they were both good... Didn't know you can test all 3 just by clamping on his gauges.

Ended up buying a new battery, but fuck, it was a pain in the ass. You have to completely remove the front driver side tire.

Started up beautifully once I finished though.

They can't test the starter at all. That's bullshit. The other two, yes.

That sounds like a bitch of a battery. My Ford Escape was a monster to change the battery on. You had to take out all the rain gutters for the windshield.

Hell yeah.. hopefully that's all it was. Someone earlier had said that a bad alternator can and will destroy a new battery. The guy did say it's good though, so who knows.

Also, this is the time of the year that batteries fail if you are living in a region that is getting into late fall/early winter. It would be a coincidence if your alternator failed right at the time of year that the cold is stressing your old/dead battery.

Frankly, cars should be built so that the user can replace things easily. Same thing with computers and phones. Whoever designed these pieces of shit to make them so fucking difficult to diagnose and repair was the dumbest fucking loser on the planet.

I mean these things are insanely complex machines but they've been extremely refined over decades and decades of people trying to make shitloads by coming out with the best this part or that system. Theres not a part made for a car that isn't like so researched and designed by scores of brilliant people trying build off each other and come up with the new shit. Like lit any part of a car you would be very very hard pressed to come up with a better one or way to do it ahit has gotten to the point the numbers are like almost as good as it physically gets. When u think about it this is as simple as it gets for a machine like this. If he just took it to the guy and had it tested he woulda had it sorted in less than an hour. That being said it used to be a whole hell of alot easier to swap an alternator on a car but most them are still basically just throw em in.

Ditto on the alternator.

The same thing happened to me last summer.  I had to have my car jump-started in order to start it.  I had already had the starter replaced, so I knew the starter was still good when I turned the key and the engine started immediately off the jump-start from my neighbor's car.

I asked my mechanic to test the electrolyte concentration in the battery to see if the battery was still good, and to test the alter-nator if the battery was good.    After testing the battery and the alternator, he said the alternator was only putting out 13.something volts DC with the engine running and should be re-placed.  So I had him replace the alternator, which ended up costing about twice what I expected, and he tested the new alternator and said it put out 14.2 VDC.

Problem solved--at least until Old Man Winter came to town.    Then one night I left the trunk of my car unlatched, allowing the automatic trunk light to draw current for the better part of a 24-hour period.
The starter wouldn't crank at all.    After remembering seeing the
trunk light shining, I got out my wall-powered battery charger and
charged the battery for 20 minutes.    After waiting 20 minutes, I re-moved the cables from the battery charger, and restarted the car.
(I keep my car in the garage.  It might have taken much longer if
the car was kept outdoors.)

BOTTOM LINE:    If you don't have another car OR a neighbor to jump-
start your car, at least get an AC wall charger to charge your battery
in case this happens.

If your alternator is putting out less than 14.something volts DC
when the engine is running, replace it.

A cold battery should read 12.something volts DC.  A 11.something VDC
battery might start the car in warm weather, but in cold weather, you will probably need a jump start.

I do too, but I wasn't pleased when I had to buy them.

I sort of understood it though when I had to use my jack handle as a cheater bar on my 1/2" drive breaker bar, and had to stand on the end of the jack handle to break the one triple square drive bolt loose. It had to be like 900 ft lbs.

You can get it on eBay for probably really cheap. You mean to tell me that people can't fix their own cars because of the specialized tools that are needed? if I ever make enough money to buy my own house I'm going to buy a lift for the inside of the garage so I can do my own damn car work.

My nephew in laws friend is pretty wealthy, ok extremely wealthy.  His garage has 2 lifts, has plumbed compressed air with a big ass holding tank so you don't run out, and has quick connects all over the fucking place so your tools can reach, its like a garage out of fast and furious but better, cause he is a certified master mechanic and can program fuel maps and ecus.  I always take my car their for mechanical work, and most of the time he does it simply for the cost of parts.

Gonna put brembos and a big brake kit on audi at all 4 corners after I push the HP up over 400hp.  Wont happen till factory warranty runs out, so I got time to research and buy the parts.
