Some put fail at 1 day others a week or the real good ones a month :D	wainuitech (129)

All the scientists served their apprenticeship at Lucas of course! Ken :)	kenj (9738)

The only reason could be is that batteries in diesel cars are bigger.	prefect (6291)

If its not a sealed battery use a hydrometer to give the state of charge. If one cell has a lower specific gravity than the others it is dying and will restrict the current available from the other cells. If all cells are even but in the red it just needs a good charge.	mzee (3324)

Ideally all new cars will be using low drain LED lights, but older, conventional bulbs will draw more power, but as has already been said, they should be suitable to power park lights overnight, with still enough zap left to crank the engine in the morning. My own car has been a bit more reluctant to turn over these cold mornings, so I decided to add some charge to some old (stuffed) batteries as a bit of backup energy. They'd been neglected for ages, needed topping up, and were all but dead. Over days of charging one, then the other I slowly got them both up to 10 volts, then the oldest one hit an overcharge state, and has collapsed to only 2volts ever since. Reportedly the newer Calcium batteries need even more care with charging, or entirely different chargers.	Paul.Cov (425)

Hmmm...husband - when he had the old ute - didn't have to get new batteries very often, but he did have a run on glow plugs once. Seemed like I was buying them every 5 minutes!	pctek (84)
1422004	2016-06-16 22:40:00	Well call me “Old Fashioned” but I would expect my park lights to be able to be left on through the hours of darkness and the car still start the next day. ;) Thats what I'd expect as well. Why call them parking lights if they cant be left on overnight :) I bit the bullet & just went & bought a new batt yesterday . $200 , about $50 more than I wanted to pay (they didnt have the cheaper version in a form factor to suit my car) 3 year warranty , so $70 a year isnt too bad. Bought from The Warehouse (Excide), they are cheaper than supercheap & repco . Turns out the old batt was only 2 years old. It's still usuable (but not reliable), so I'll keep it as a backup .	1101 (13337)
1422005	2016-06-17 00:00:00	if your doing a lot of short runs, especially stop start crawling in traffic driving, i would throw the battery on charge every so often. either with an automatic or trickle charger so you don't overcharge it.	tweak'e (69)
