Are you going to let a computer inform you when to change your battery, that`s foolish, didn`t happen pre stop/start.
If your car has a BMS, before replacing the battery and spending your hard earned disconnect the sensor (BMS) attached to the neg clamp of the starter battery, fully charge the battery with a Ctech or similar and drive the car. By disconnecting the BMS the EMU controlling the alternator will default it`s charging regime from smart to a continuous standard charge voltage of between 13.8 to 14.2, this will keep the battery fully charged even with short journeys. With smart charging in play on cars with regeneration the EMU has to leave room in the battery for energy regeneration, it won`t allow the alternator to charge the battery above 75/80% under engine power, this means if there is little regeneration or the car does mainly short journeys the battery is often only partially charged for lengthy periods. With the BMS disconnected there is no need to code a new battery as the EMU does not now know what type of battery is in the car. Any sealed lead acid battery can now be used with the same amp hour rating. There is no down side to this, this works on numerous makes of vehicles including Ford, Porsche and Merc as early as late 2011.
Regarding no down side, if you love the stop/start system disconnecting the sensor deactivates stop/start so for those drivers there is a down side.
