11 Volt = Failed

Mileage: 99,827KM

Today, a year, 5 months and 15 days (from the last replacement), I had a flat battery. Just in time for me to go home from work. I thought I had a failed fuel pump or coil pack failure etc. because of no warning beep from BSI. The engine started for a second and shut down afterwards…



Using a multimeter, the voltage registered was 11 volt. No wonder everything works perfectly except it cut off the engine after a second starting it. I think, the ECU purposely cut it off due to low voltage from the battery. After jump start my car, I drove to a nearby workshop. Actually, it was 15KM away but nearer to my home.

The previous battery was GP Atlas MF battery, bought on February 9th, 2012. The replacement is Panasonic MF battery. Both are DIN55 class. The latter is a bit pricey but I have no choice coz I can’t shut down the engine and moreover it was near to 7PM. Most of the workshops are starting to end operations at that moment.

Not sure how long the replacement would last but a year and half is considered quite good for nowadays battery.

  1. Hey Bug.. I have been noticing this. Most of my friends car which has volt regulator install tends to have their battery give within one year.

    I believe the reason is because capacitors are not good energy retainer. When engine is shut, the battery will continuously charging the capacitors and will do so untilthe lasts drip of battery juice.

    I don’t have this install on both my cars, Pug 206 and Myvi and I usually get around 3 yrs plus of battery life in average. Just sharing my thoughts.

    1. Thanks for sharing. For my case, with or without voltage stabilizer, my car battery will give up within 16 – 18 months. I have been tracking the battery life since I bought the car. Let see how far this brand will survive…
