Car Battery Question

Likely a loose connection to starter based on things said

Same guy here from previous comment...

You should honestly know if it could be your battery if you have owned the vehicle...

How old is it? More than 3 years buy a damn battery. If it's less, how many times has it went dead? More than 10 times, you're effd...

Otherwise battery is probably fine.

Voltage isn't necessarily a perfect indicator, sometimes they will hold charge but won't have cold cranking amps because of the above..

If battery is fine and holds a charge, disconnect negative terminal while.running, does car still run? If so alternator is fine .

Then check big red cable to starter, make sure tight, check ground. If still clicky it's solenoid.

Not super hard to figure out

Battery. I've bought 4 batteries this year. My mower, the truck, my car and the bitch's car.

It seems batteries are failing open these days. A 12V battery is actually six 2v batteries connected in series internally. When a bus bar goes open it won't carry any current, even though you see it with a meter.

I put in a lot of batteries at work too.

Wal mart still has $50 batteries.

Ignition short.

Check your connections from the ignition to the solenoid/starter

You never know, asians have been crawling under SUV’s here and stealing parts for resale.

Little bastards

If it's a lead acid, it's not 6 cells, well I guess you could say it is, really it's 6 plates...

Those plates used to be quality thickness and could be refurbished but as time goes on they get thinner and thinner...

If I had a full size battery in my car I would buy a marine battery which often has thicker plates like the old days.

When a battery has thick plates you can refurbish them yourself with a high amp charger easy peazy.. you can still do on cheaper ones but less effective and not as many times

To make it worse, when buying a battery, check the dates, but the NEWEST date POSSIBLE as they don't maintain them in stores.

A toggle switch will burn up LMAO.
You need a battery disconnect switch to handle the current.

A quick way to check the solenoid.

If it won’t start, get out and rock the vehicle.

Back and forth a bit.

Then get in and try again.

If it starts its the solenoid.

Bad news is most solenoids (which used to be cheap) are now a part of the starter so you’ll have to buy both (a single unit).

Good news its an easy replacement, wires and a couple of bolts (once you loosen the belt and idler).

Reread what I said...

A battery with 6 actual cells is basically 6 batteries, which lead acid are not.

If I said anything wrong it was the number of plates, but that's probably changed too..

Now either take the info I gave you and do something with it, or don't, and continue to show useless diagrams that are basically not going to inform anyone of anything.

When you refill a bettery, you usually refill in only 2 holes at max, on very rare occasions 6, it's basically one battery, not 6

If you have a volt meter place the red wire on the positive terminal and the black on the negative it should be around 12.6-12.77 for a good battery, Now start the car to see if it is charging, if charging the voltmeter will read 14.0+ volts if the volt meter falls below 12. 0 volts its not good.

The battery will only last three to five years. There are lead plates inside and after time their surface area diminishes so although it may have a 12 volt charge it's capacity is diminished. It's just time for a new battery.

If a 6 cell battery went dead, it could be one bad cell and you could replace it...

Good luck trying that on a car battery

A cell is 2v. Doesn't matter how many plates or how big it is, it makes 2.05v due to chemistry. So to get the voltage we require, they are linked with connectors or bus bars. A 6v battery has 3 separate 2v cells. 12v, 6. 24v, 12.

I used to run the battery room in a big warehouse. We had 4800 lb 48v batteries. Each battery was comprised of 24 single cells linked externally with bus bars.

I knew dude would say something dumb

Not 14v, jeesh.

I'd get a new quality battery, a 60 month heavy duty one. A good battery, like a Die Hard can run you $225-$250. and get a remanufactured alternatornew alternator. If you're in a hot climate, batteries will not last that long. Typical 5 year battery in Florida lasts about 3 years, even with a 5-year battery. If you have a reliable, honest, mechanic, they should be able to steer you right for under $600. Alternator you can get remanufactured for about $125. Most mechanics charge about $75/hour.

Man, the stuff people come up with. Sprinkle some crack on it.

If this were a manual transmission and there was a patch of teeth missing off the flywheel, this would work.

Good batteries can last a long time, the AGM on my motorcycle is ten years old and still sits at 13v.

AGM type batteries are worth the extra money.

Jumping a car battery can be a risky operation. Hopefully you didn't fry your ignition module.

If you did, it will have to be replaced. To save yourself a BIG chunk of change, do the work yourself.

I once had to change mine in the middle of winter, while outside and it was snowing. No fun!

Real simple.

Take it to an Advance Auto or Auto Zone.
Ask them to check your battery, explain what it is doing.

They will test not just the battery, but the charging system as well, and its free.

If its just a battery, they can replace it for you for no charge, as long as you buy the battery from them.

If its your alternator or something else, they can point you toward the best place to have it repaired.

FYI. You do not always have to take your vehicle to a dealership for repairs.
This is usually the most expensive option.
As I said, ask the guys at the auto parts store.
They deal with this stuff daily.

After you fully charge the battery, does it click or does it try to turn over a bit before it clicks
Test the voltage before trying to start it, then immediately after
I'd expect you need to replace the battery, but this will give you an idea

what actually happens is the lead corrodes over time and drops to the bottom of the battery compartment, shorting out the battery cells.

If you were to clean your battery every few years (youtube it), you could easily get 10 years out of a good, quality battery.

Man most of you fuckers really dont have a clue.

Its not the battery!

For fucks sake just hook the jumper cables from the one car to the others terminals its simple as fuck and then everyone will shut up about the battery.

Op will go get a battery and have the same problem I guaran-fuckin-tee it.


I will throw this out there that sometimes alternators can actually drain the battery its from the diodes going bad.


This is what dip shits do throw parts at it.

That only works for vehicles that are older than 1990. Newer vehicles have the battery wired in series. As a result, the vehicle will die when you disconnect the negative. Never disconnect the positive lead and then try to re-connect it. It throws a positive voltage spike to the sensors and computer and could damage them...

Newer vehicles use the alternator to charge the battery. Older vehicles used to use the alternator to run the vehicle and charge the battery...
