Jaguar XJS · Battery replacement
The right battery for your XJS, fitted where the car is, with the charging system tested before we sell you anything. Covers model years 1975-1996.
If your Jaguar XJS 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.
AGM throughout, with battery monitoring that needs the replacement registered before the charging system will treat it as new. On the XJS specifically, which the vehicle database lists across model years 1975 to 1996, 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 Jaguar XJS with a failing alternator leaves you exactly where you started, two days later.
With a range ending in 1996, 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.
Ingenium engines are sensitive to oil condition and to coolant level; both deserve checking at every visit rather than every service. For the battery specifically: park in shade where you can, drive far enough to actually recharge rather than only starting the car, and have it load-tested before summer rather than after. A battery that reads 12.4 volts at rest can still fail its load test, and the load test is the one that predicts the morning it does not start.
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.
