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.
New gen cars nowadays have smart charge system, example below is a simple 1hr. datalog of speed vs. battery voltage from my civic RS equipped with smart charge. My ford cars have this as well. As you can see, batt. voltage went from as low as 12 volts to as high as 14.7 volts on different occasions. ECU constantly adjust alternator charging output depending on the load, battery condition, temperature, throttle, coolant temp, etc. to help save fuel, extend alternator life and give extra bit of power at WOT.

Now, If I will put a volt meter on my car and doesn't know what this tech is, baka madalas ako magreklamo sa Casa na bakit bumabagasak voltage reading ko sa 12volts, and knowing Casa techs, baka naka ilang palit na ko ng alternator thinking na sira nga ito... LOL.



BTT: Mostly sa starting system, so expect short life expectancy from your carbon brush, armature and starter solenoid and relay. Do a financial study na lang, how much parts na ito and labor cost vs. matitipid mo sa gas in 5 years of doing this practice.

Cars equipped with auto start/stop function have beefier starting systems so please don't compare to reg cars.
