Subaru Legacy B4 · Battery replacement
The right battery for your Legacy B4, fitted where the car is, with the charging system tested before we sell you anything. Covers model years 1998-2020.
We fit Subaru Legacy B4 batteries where the car is — office parking, driveway, or the hard shoulder — and we test the charging system before we sell you anything.
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.
Head gasket and oil consumption history is worth checking on any used Subaru here, because heat is exactly the condition that surfaces it. 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.
The Legacy B4 is a saloon, which usually means a mid-size battery in an accessible bonnet position. 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.
The boxer layout leaves a shallow battery tray, so height matters as much as capacity when choosing a replacement. On the Legacy B4 specifically, which the vehicle database lists across model years 1998 to 2020, 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.
Same workshop, same technicians. Open a service for what it involves on your car.
Two to three years in Dubai's climate. Anything past three summers should be load-tested rather than assumed good.
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.
