My car battery is 13 years old and rolled off the line with the car and I just tested it--still good with 80% charge.
How long do your batteries last, /o/?
Not 13 years
How do you know its the one that the car rolled off the factory floor with?
>>14011398
Is it a Panasonic?
I have a 2002 XJR that still has the original Jaguar branded battery in it dated 10/2002, works fine.
How old is the car?
Mine lasted 14 years, seemed to be doing fine, but just gave up one day.
Car was a 2001 2.2 ecotec vauxhall.
>>14011398
got a 6 year old in my truck
sits at around 12.3v with the lights on
>>14013390
That's not good.
Test that battery under load. Unloaded doesn't mean much.
>>14012038
Gotta be a Panasonic.
>>14012338
Made in Spain, nigga
every 3 years when it starts expanding and eating shit.
i assume its because of how hot it is where i live.

Phoenix az. New batteries every 3 years or so.

Im not too worried about .3v

>kept my original truck from when I was 16
>don't drive it anymore
>stereo drains battery, if I forget to use the tender
just don't put in some negro stereo system and they tend to be alright.
Ferrari 458 you have to use a tender if you leave it for more than a week though. They give you the tender. Ferraris are garbage though so to be expected.
>>14016161
You should be.
>>14016189
On a 6 year old battery?
>>14016278
Yea.
>>14013390
A fully charged 12V battery should be around 14.5V.
>>14016341
No, god no. 14.5 is float charge voltage. 12.6-12.8 is normal full charge voltage.
>>14016349
>No, god no
You're mistaken.
>>14016341
I think you mean that the alternator should be putting out around 14.5V to the battery
Battery by itself unloaded should be about 12.6
>>14016355
I am not.
a-am I good /o/?
>>14016356
14.5V is a maximum, too. The acceptable range is 13.8-14.5V.
>>14011398
I replaced the one in my 12 year old car last week.
The one that was in there wasn't the original...
>>14016384
You good family.
>>14016385
Yup, should've added "unloaded" aswell, aka minimal lights on, battery in good shape, no AC or stereo on and so on
>>14016397
OK. So, I take a multimeter to a fully charged battery of a car and it's disconnected from the rest of the vehicle. What voltage am I looking for (range wise)?
>>14011398
just because the battery has 80% voltage left doesnt mean it's not fucked or something
what if it has 12 volts perfect and 2 amps, is it still perfect then you dickhead
>>14016425
12.6-12.8V depending on age of battery.
>>14016384
your car can do 30000 rpm?

Ferrari's rev upto 100,000 rpm now too?
>>14016520
That's the rev counter for a Ferrari x100.
Since you're only driving one Ferrari, you have to divide the revs by 100. So it only revs to 1,000 rpm.
>>14016533
I'm astounded people can figure out how to use a computer but cant do simple as fuck math.
if you're dividing by 100, wouldn't 100 RPM's become 1?
>>14016533
>So it only revs to 1,000 rpm.
>american cars
>>14016548
yeah but rpm dials are always x1000 you dip shit

There is a greater intention behind this, we're all just to dense to see it... right?
>>14016558
clearly not. look at mister Ferrari, or that bigass truck that was posted.
>>14016574
jokes on you none of those posts are by me
>>14016574
Buckle up, you're in Straya now.
>>14016355
He is correct. 12.7v is good for a sitting 12v battery.
Motorcycles float between 13.5v up to 14.5v depending on the charging system and cars are usually 14-14.5v. But all of this is when the charging system is operating, ie. engine running,
>>14016301
Why is that?
>>14016341
12.3 is with the lights on, car is on but not running
When running its about 14.3
>>14018431
Because it is low.
