If it has a decent alarm system & radio that needs permanent live(most of them) then it'll flatten quite quick especially if it wasn't fully charged before hand and/or coldish. They really need a float charger if not used every day or so. |

Hi  What year is your 928 exactly ?? The reason I ask is that there are two sizes.... Both are which are HUGE, and normally do not need a trickle charger , they should still start the car after months...unless either the battery is faulty (too old) or the alternator is not properly charging it. All the best Brett

Being an ex-pat I leave my 928 for between 4 to 6 weeks at a time. The battery does not like it and often went flat even with a nearly new battery. I know use a solar trickle charger which seems to do the trick. Stephen |

If there's no abnormal drain and battery is ok then it shouldn't flatten like that after only 7 days. But battery maintainers are very useful. I hook mine up whenever I leave her in garage and don't think about when I'll next be driving her. Mine's a CTEK which are nice quality units (bought from Hamilton Classics) but any decent brand/Halfords should be fine. I use croc clips to charge post and convenient ground but you can attach a neater lead to the battery. With clips I don't forget it's attached - a 928 owning mate (come in Decasmo) chipped his spoiler driving off with charger attached! |

You can tell, remove the battery and look down into the hole...you will see what looks like a corner BASHED in by Porsche lol.....its for the twin pipes of the exhaust to get past the battery carrier. So you will need the slightly smaller battery...which i cannot remember the number of but it is ONLY available for the 86 year....mine is a Bosch. All the best Brett

Measured the voltage and only 10.8V present.. have now removed on placed on charge. The battery looks quite new..but a cheapish/not well known make and no "flattened corner" 73a/ph type.. might buy a new one anyway and keep this as a spare.

Hi Just in case you misunderstood me.. the flattened bit is in the hole....not on the battery.... I think mine is a 96 ah.. All the best Brett
