Porsche 928 · Battery replacement
The right battery for your 928, fitted where the car is, with the charging system tested before we sell you anything. Covers model years 1977-1995.
If your Porsche 928 needed a jump start this week, the useful question is not which battery to buy. It is whether the battery is the fault at all.
The 928 is a coupe, and the tighter engine bay means battery height and terminal orientation matter as much as capacity. That is not a detail — battery choice is driven as much by physical size, hold-down type and parked current draw as it is by cranking amps, and getting one of the three wrong is how a correctly-specified battery ends up failing early.
AGM as standard, and cars that sit between weekend drives benefit from a maintainer — a Porsche that is used twice a month is a Porsche with a chronically undercharged battery. On the 928 specifically, which the vehicle database lists across model years 1977 to 1995, the safe approach is to read the label on the battery that is in the car now and match its group size, terminal side and capacity — or to give us the year and let us look it up.
One loud click with bright dashboard lights is the starter. Rapid clicking with dimming lights is the battery or a corroded terminal. Starting fine and then dying while driving is the alternator. We test all three at the roadside before fitting anything, because replacing a healthy battery on a Porsche 928 with a failing alternator leaves you exactly where you started, two days later.
With a range ending in 1995, this is very likely a conventional car with no start-stop system, which means a good standard battery in the correct group size does the job. AGM would last longer but you would be paying for cycle life the car never uses.
Same workshop, same technicians. Open a service for what it involves on your car.
Yes, at no charge, and it goes to a licensed recycler. Lead-acid batteries are not general waste and should never be left in a car park.
Two to three years in Dubai's climate. Anything past three summers should be load-tested rather than assumed good.
