link is not working i also get battery manager come up ... but one thing i do know is that the battery allegedly always saves a portion of power for starting the car ... so it will shut down any luxurys ... stereo .. auto boot.. keyless entry ect ...to ensure you can always start the car and i think (dont quote me ) that the battery will be fine and its a management issue .. unless your car physically wont start or really struggles to start then the battery is fine and the managment is having an epidemic shutting things down to preserve power to start the engine when really you have plenty of power
would be interesting to see how the update is done ect if you can post another link
