1106581 2010-06-05 07:19:00 OK, will buy a charger and charge it and we'll see what happens. george12 (7)
1106582 2010-06-05 07:47:00 They can even till if it need replacing without it being fully charged. Buying a charger can be half the price of buying a battery.

1106583 2010-06-05 08:05:00 ^ yeah no need to fully charge it, partial charge will be fine. If its still cranking the car, this should be fine. Alex B (15479)
1106584 2010-06-05 08:46:00 OK, will go get it tested then :)

Thanks everyone.

1106585 2010-06-05 10:16:00 If you are reving the engine when you test the battery then I would say 13.8 volts is too low for the alternator charge cut off voltage, it should be about what your Mum's is ie about 14.5 volts, it is not being charged properly by the alternator.

Presumably you have an alternator and not a generator, an alternator is a big improvement and should fully charge the battery even on short runs.

your going to need a charger one day and they are fairly cheap these days, try to get one that displays charging current.
if they are going to do a drop test then it needs to be fully charged to do a decent test and see if it holds full voltage.

the battery if probably half charged and will continue to go down until you do a decent run or charge it up. batteries don't like sitting at part charge. try to keep it fully charged up it will last longer.

trouble is you go to a sparky and he will say its stuffed and sell you a new one regardless.

1106587 2010-06-05 21:34:00 Did you try the start test I mentioned earlier? What reading did you get? And also read the document/site? That listed possible causes - including low water. Perhaps test again once you get the battery charged, if you get start/battery problems. kahawai chaser (3545)
1106588 2010-06-05 21:42:00 When you take it to a auto electrician they will most likely test it with a hydrometer to test the specific gravity of each cell. If a reading is down in one or more cells the battery is past its use by date. See Here (www.batterystuff.com) for more info.

1106589 2010-06-06 01:43:00 Well, yesterday I bought a new battery, the car was a bit reluctant to start one morning last week, and yesterday it was unhappy about even turning the car over. (Last trip was 3 days earlier, in daylight, 35 KM.)
It is just one thing after another with that car, 2 or 3 oil changes every year, new front tyres last year, new anti-freeze a month ago, hydraulic fluid change barely 8 months ago - where will it all end?
