Start-Stop & high energy demand batteries
AGM or EFB battery for start-stop vehicles and for cars with high energy demand (many electrical consumers, frequent starts). More charge cycles, better charge recovery and longer service life.
This engine comes with an AGM/EFB battery as standard: the car's charging system requires it even without Start-Stop. If in doubt, message us and we will confirm.

Frequently asked questions
- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your RUF Ultimate 3.6 battery compartment and the positive terminal position matches.
- The Ruf Ultimate 3.6 requires a battery with the correct capacity (Ah) and Cold Cranking Amps (CCA) for this engine. Compatible batteries offer 95 Ah, 850 A (CCA), 12 V, case H8/L5, Start-Stop (EFB/AGM) technology. Browse the compatible battery list below.

- To find the exact battery you need, you need to know the make, model, and engine. If your car has a Start-Stop system (the engine shuts off at traffic lights), you need an AGM or EFB battery. An AGM battery can only be replaced with another AGM battery. However, an EFB battery can be replaced with either another EFB or an AGM battery, as the latter is superior.
- The standard battery is the conventional type. The EFB battery withstands start/stop cycles better. The AGM battery is the most durable and is mandatory in cars with Start-Stop and regenerative braking. Never replace an AGM battery with an EFB or standard battery.

Guides
-
This vehicle uses an AGM or EFB Start-Stop battery: after any replacement it must be registered via OBD so the BMS applies the correct charging profile. Without this step, the battery service life could be significantly reduced; on some vehicles (BMW, Audi, VAG, Mercedes) the alternator may stop charging it altogether.
