To replace the battery in the Opel Kadett E 1.8 S: 1) Disconnect the negative terminal first, then the positive. 2) Remove the old battery. 3) Install the new battery with the same specifications. 4) Connect positive first, then negative. 5) If the vehicle has a battery registration system, register the new battery with an OBD scanner.
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.
