The vehicle may use either a sealed lead-acid battery or an AGM (Absorbed
Glass Mat) battery. Lead acid battery contains liquid sulphuric acid and can
spill when overturned. AGM battery (known as VRLA battery, valve regulated
lead acid) also contains sulphuric acid, but the acid is contained in glass mats
between terminal plates.
It is recommended that the replacement aftermarket battery has the same
specifications, such as capacity and type, as the exiting battery. If the original
battery is replaced with a different type of battery (e.g. a lead-acid battery is
replaced with an AGM battery) or a battery with a different capacity (mAh),
the vehicle may require reprogramming of the new battery type, in addition
to, performing the battery reset. Consult the vehicle manual for additional
vehicle-specific information.
Register Battery Replacement
This option displays the mileage reading of last battery was replaced,
registers the battery replacement after replacing a new battery and informs
the power management system that a new battery has been installed.
If the battery change is not registered, the power management system will
not function properly, which may not provide the battery with enough charging
power to operate the car or limit the functionality of vehicle’s electrical
systems.
Take BMW as an example.
