later when try claim the battery then there will be 1001 terms & excuses for you.

Don't forget only can sell back to perodua, so if I want to change other brand will they reject me?

then next question, since the battery is on rental, so if it cause any damage or fire to car who should pay for repair? does not make sense for me to loose my NCD if the damage is caused by the supplier's bad product right?
