When was the last time you put a multimeter on your battery?

i know random question, but after having small running issues with my car, and then a problem with it not wanting to start, i checked the voltage, and it was too low, so swapped for a new battery and it runs like a dream now

my faulty battery the readings it gave were:

11.7 before starting, and 11.9 - 12.5 when running

my new battery:

12 on start up, and 13.5 when running

i demand everyone goes out and gets their readings, i bet at least one person comes back with wrong readings

mine last month was 7v therefore i knew it was bollocksed as it only cranked half a turn
my new battery is 12.2v before starting and 13.5v running

Didn't have time last night after it wouldn't start making me late for work!

Mine cant be knackered as its not very old at all! Still goes flat tho

[DKnight]

check it! please even people who think theres is fine, i guarantee we will solve someones problems!

[vwmk3jon]

I think mines just due to a naff earth somewhere. The last multimeter we plugged upto my car died! lol.

iv had the same battery in 6 of my polo's lol and it still 12v on start up, and 13.4 when running

that's a dangerous assumption to make, even an almost new lead acid battery can be knackered if it's been left uncharged for a length of time.

Thanks Dan more stuff to check and spend money on :-)

Luckily only just serviced the thing so all is good, but a fair point to make i think.

its one of them things you just dismiss, but like i said, my car runs sweet now, no start up issue at all, and general running is much better

Paradox much?

hahahah

It's either not holding it's charge or something is draining current. Can't be that difficult to sort out.

If you do a lot of very short journeys ie daily commutes, your battery's going to have a much shorter life than if you give it a regular twenty mile trip. It's a bit of a bummer if your pride and joy sleeps in the street, but regular overnight charging is well worth it.

Could say that. Having to work around everything that could be causing it (so that'll be checking the whole engine over!). I'm sure we checked the battery though and it was fine when we got the thing fired up again.
