Medyo off topic.
With the technological advancement in automotive industry, bakit di pa isama ng mga car manufacturers ang voltage reading na battery sa dash ng mga kotse ngayon? If I'm not mistaken meron warning pag malapit na maubos pero it's not functioning naman ata? I'm not also sure dun sa mga high end cars kung meron? May 300 pesos battery voltage reader nga sa lazada

, you'll wonder bakit di pa nila masama knowing how important battery is na pwede ka itirik in case of emergency.
Also, is there a way to know how many times you started your car already? Like a start counter? If none, it would have been helpful, like in my case, My 3 years car only has like 15k odo pero I'm starting it like 3-4X a day in a very short distance trips. Ayun bumigay starter agad :D it would have been helpful for you or the the mechanics to diagnose a car problem.
