Subaru Justy · Battery replacement
The right battery for your Justy, fitted where the car is, with the charging system tested before we sell you anything. Covers model years 1984-2026.
If your Subaru Justy 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.
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 Subaru Justy with a failing alternator leaves you exactly where you started, two days later.
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.
Battery choice on the Justy is driven as much by physical fit and parked current draw as by cranking amps. We check all three against the car rather than against the model name, because trim levels within one model can take different batteries.

On this range it is under the bonnet, offset to one side of the flat engine. If yours is a variant where it sits elsewhere, we will confirm before quoting.
