karlp606 Posted April 23, 2018 Report Share Posted April 23, 2018 My boxster has been at Revolution the past week getting the leaky passenger side fixed, after speaking to Danny he asked me if I needed to jump the car off a lot as the battery kept going flat whilst at RP, it's always been fine at mine and never needed jumping off, so drive the car from Leeds to Hull thinking that would give it a good charge as its only been moved around the garage at RP, but tried to start the car again today and no joy flat as a pancake! So do you think these symptoms suggest a new battery or its just lost charge whilst at RP and I should buy a trickle charger??? m Link to comment Share on other sites More sharing options...
Topbox Posted April 23, 2018 Report Share Posted April 23, 2018 How old is the battery? A drive from Leeds to Hull would put a decent charge in - sounds like a new battery to me. The one on my daughters Corsa went from fine to U/S in a day. I would recommend you buy a battery conditioner whatever the outcome if your car is not a daily. CTEK are excellent but pricy - Lidl sell a good one in the winter for about £20 which a good few folk on here have. The conditioner is a bit more sophisticated than a trickle charger as it can be attached permantly when the car is not in use keeping the charge topped up.It will not charge a completly flat battery though, for technical reasons I don't understand ?

Battery looks a lot newer than a original and has never shown any problems before, cars been left parked up around 3 weeks before. I presume as you said a conditioner/trickle charger won't get the battery going again? :/ Link to comment Share on other sites More sharing options...
Topbox Posted April 23, 2018 Report Share Posted April 23, 2018 A decent garage can test the battery and tell you if its any good or not Link to comment Share on other sites More sharing options...

mikefocke Posted April 23, 2018 Report Share Posted April 23, 2018 1. Battery gone. Test battery before replacing. Requires battery be charged. Any battery shop could test. No special Porsche tool needed. 2. Alternator or voltage regulator. Test at battery connection points with voltmeter with engine at idle and at 3k. Any battery shop could test. No special Porsche tool needed. 3, Parasitic draw developed. Test by removing fuses one at a time and seeing if still happens. Link to comment Share on other sites More sharing options...
mikefocke Posted April 23, 2018 Report Share Posted April 23, 2018 There are chargers, maintainers, tenders, desulfication units and trickle chargers and even some expensive units which combine several of these functions. Some maintainers require a moderate charge of the battery to be present before it can be maintained. I actually have a charger which I'd use for maybe 4 hours or so, a maintainer which I'd use for weeks , a multi-meter which I'd use to test voltage or current draw, and a load tester.

PaulQ Posted April 24, 2018 Report Share Posted April 24, 2018 The Hankook batteries are excellent value. Made in Korea, the manufacturer of them is a large oem supplier. Link to comment Share on other sites More sharing options...

I think that's the one I bought last year along with a Lidl charger for £14 to keep it topped up between runs. Mine had a vent on it which you connect to the piece of piping in the battery tray which vents to below the car any hydrogen that get generated.

karlp606 Posted April 24, 2018 Author Report Share Posted April 24, 2018 Presume swapping out the battery on the boxtser will be the same as any other car, just lose radio code etc. Just hope the doors will open when I get the battery tommorrow to get the frunk up!

Swapped it tonight, car still opened thankfully! nice and easy, old battery eye view hole thing was completely dark so showing no charge, it was a excide battery, didn't look that old but doesn't look a brilliant brand.

PaulQ Posted April 25, 2018 Report Share Posted April 25, 2018 Sometimes you need to shine a torch in the magic eye to see if they are green. Exide is a decent brand btw, but glad you got it sorted Link to comment Share on other sites More sharing options...
