And during its normal operation,- it is the alternator which is delivering the power, regulated/supported by the battery

Bro- I do not see a need for a backup... It's like having a backup gasoline tank,- when the OEM is more than enough...

Afraid of not being able to start a vehicle? Jumper cables or replace the battery when its warranty period expires for peace of mind...

correct sir.. and many batteries like the philippine national battery (moto) will display "12 volts" but will not have enough juice to drive the starter motor..

ilang beses na din kami nadale nyan.. umuwe ng haus good cranking power pa.. next morning wala na..

pwede din bumili ng battery tester.. yung electronic type.. based on my experience, na detect nya kung nasa end stage na yung battery..
