Before reconnecting the battery, some people recommend that the ignition be turned to the on position (position II). After reconnecting lock and unlock the car with the key. Failure to do this has sometimes resulted in the car not being able to be started.
Vehicles with Battery Monitoring Sensor (BMS):
Use VIDA to reset according to DIAGNOSTICS/VEHICLE COMMUNICATION/CEM/Advanced/Resetting information when replacing main battery.
Selecting a replacement battery:
From my experience, battery manufacturer websites can give misleading information. For example, some manufacturers recommend a 700CCA AGM type battery as some S40/V50 are fitted with start/stop. But for base models Volvo specify a 590CCA battery.
You can look up what battery Volvo specify for your model using VIDA or one of the online equivalents. The battery rating varies depending on certain features such as sound system and start/stop.
Battery part numbers - apply to 2006 S40/V50:
The battery size is 278x175x175 mm, may be called N66 or DIN65. Larger batteries may fit but may prevent the plastic top cover/vent from fitting properly. Ensure you get the correct connector layout and that the CCA rating meets that specified by Volvo at a minimum.
