CCA = cold cranking amps, a standard use in winter countries.

I don't think we need that lol

nope, this rating only for winter country weather.

last time i bought my Varta he show my how high is the CCA.
when i went back only know that CCA is not applicable at our weather 

RC is more important cuz it's discharge of amps before battery dying
AH is amp hours, cuz we have massive electronics in our cars, and if your car has audio system which u keep bombing it. AH = amp hours. capacity it can give every hour

Cold Cranking Amps (CCA)
CCA is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. Generally speaking, it is easier to start an engine in a warm environment than in a cold one. The rating refers to the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. The higher the CCA rating, the greater the starting power of the battery.

Consider the CCA Rating if You Live in a Cold Climate
If you live in a cold climate, the CCA rating is a more important consideration than it is if you live in a warm one. Battery starting power deteriorates as the battery ages, so a battery with higher starting power should give you more confidence over time. Replacement batteries should equal or exceed the OE battery in ratings. Replacing a battery with a battery that has a lower CCA than the original equipment may result in poor performance.
Reserve Capacity (RC)
RC is a general indicator of how long a new, fully charged battery can continue to operate essential accessories if the vehicle’s alternator fails. It identifies how many minutes the battery can deliver a constant current of 25 amps at 80°F without falling below the minimum voltage, 1.75 volts per cell, needed to keep your vehicle running.

That the good thing about competition. Everyone is upping their game to increase their product market share and we as end users benefits from this healthy competition.

Warranty Period : Don't just take the seller's word for it !

Was inspecting an imported battery today afternoon. The reply for warranty period was 18 months. Not bad I thought, until I opened the packaging for a closer inspection wherein it's clearly stated 12 months in large FONTS !!! So I told the staff, how does your lady boss intend to cover another 6 months ? He just smiled.

Granted that each & every battery are different from one another even if it's from the same conveyor belt, the best chance for longest lifespan is the Warranty Period.

After which, I start comparing apples with apples, i.e. Batteries with Longest Warranty Period, Catalogue Number & Technical Data Sheet vs Price.

Finally after making the purchase, it's all about wise battery management until its warranty period is over and trying to squeeze additional Period out of it.

Since my recent battery purchased couldn't crank the car within 2 months of usage and despite recharging it, it's unable can to hold its charge. Now I am awaiting an official reply from the manufacturer regarding this weird battery that I have. I've been promoting this X brand to all my friends since I've reached the 4 year lifespan with my last X brand battery but since this incident, I will now have to reconsider my loyalty to this battery manufacturer.

I'd buy exide matrix, it has more CCA than both of these batteries and has the long warranty like the amaron. Hope this helps you. If you live in klang valley I can recommend you a good seller of this brand.

Yes, without any doubt a weak battery will cause problems especially if its in today modern car with all kinds of power guzzling electronics. If its in an old junk, there's nothing to worry about.

Underpower is the 1st sign that the battery is going to die.

Though your weak battery is able to crank the car at the moment but it wont be for long. How long before the battery finally fails to crank the car, is really anyone's guess.

However, 1st generation Myvi I believe the minimum requirement is 100 CCA, anything less with not start the car anymore.

Is your battery WET type and size NS40ZL ? If I were you, this is the time to investigate for the best battery on the market. 😊

The results shows
Battery Test = Good Battery
Starter Test = Normal
Charging Test = OK

everything looks good, why did the Service Advisor ask to do a battery replacement ? On what basis ?

Recently my client returned from a Service Center and was told he needed to change his battery. I tested everything and it looks fine a week ago and today the battery is still OK SoC 98% SoH 100%. So I told my client whenever anyone asks him to change his battery, try to get their reason for doing so and revert to back to me.

Are you in Melaka ? If yes, I would like to run some tests myself on your vehicle to verify that everything is actually OK. Based on recent events like my client being given incorrect advice, I think it's better that I do things myself.

Truthfully that is the weirdest excuse I've ever heard "Could go flat anytime". If what he said is true, then replacing a brand new battery and the tester will produce the same results as well Good Battery, Normal & OK. So the new battery could be flat anytime again ?

The only possible excuse that I can come up with to validate his claim of flat anytime are
1. The tester is faulty OR
2. Incorrect S.O.P.

If I ever gave excuse like that to my clients, I sure kena maki hamun by my clients. 🤣🤣🤣
