    Is there any advantage or disadvantage when changing battery to the next higher capacity? Assuming the uprated battery could still fit in the battery holder of the car and the terminal size is the same. Will it be an added cost only? Will it affect the performance of the alternator in the long run?

    No idea kung makakatulong... Pero nung 90's palaging bigger battery ang kinakabit namin sa mga cars namin... Hanggang 3SMF kung kasya

    I recently change my battery and check the specs of 2smf amaron hi-life and 3smf amaron go... both have almost identical specs so I did choose the hi-life because of the added warranty period compared to go. Advantage of having the next higher capacity is of course warranty period and the reserved capacity of the battery will be much higher and also the cold cranking ampacity so it will deliver more current when you start your engine.

    Off the top of my head:

    Pros:
    1. Higher reserved capacity
    2. Higher cranking current capacity
    3. Will usually last a little longer than a smaller battery, all else being equal, as the depth of discharge (DoD) is shallower
    4. More forgiving when you have a lot of accessories and/or use them extensively with the engine off

    Cons:
    1. Slightly higher upfront cost
    2. Typically heavier
    3. Potential fitment issues

    in my case, i did the opposite.
    i got the next smaller battery.
    i did not notice any unfavorable finding.
    even the battery life did not seem compromised.
    gasoline engine.

    naalala ko bigla... car ko lang pala gasoline nung 90's

    lahat ng other cars namin were diesel, hence yung bigger battery helps during morning starts (especially during colder weather) dahil sa heater

    for my car... since puro 3SMF yung spare namin... yun na din ginamit ko. hehehe

    We do this too. Get the biggest battery that will fit. Another benefit is less down time because of the longer lifespan.

    Noticed car manufacturers are fitting the smallest batteries they can get away with nowadays. You'll notice the batteries provided are always smaller than what the slot is designed for.

    because under normal use, car battery is only used for starting the car.

    now if you have an audio / video setup and use it while the engine is off, that will be a different story.

    smaller battery means faster charging time, less concern for battery discharge
