Seldom use ur car ?

Couldn't the battery be removed to save it, instead of letting the battery sit idle in the vehicle provided your vehicle allows it's removal without affecting the electronics.

Anyway what did you meant by bought in June 2019, "still OK and using" ? Did you mean that it was left sitting idle in the vehicle for 2 years and now that same Amaron is still OK and that you are still using the same Amaron battery after 4.7 years ?

Then the duration calc wasnt correct
Should 2.7 yrs only after minus 2 yrs

Impressive. Whatever vehicle that battery is in, is a keeper, cause I do not know or have come across any vehicle that does not drain a RFB battery left sitting in the vehicle that is left idle for 2 months and more, let alone 2 years in your case.

To clear any doubts, this Amaron battery is it a Regular Flooded Battery either Wet Cell / Dry Cell OR is it an Àbsorbed Glass Mat (AGM) Battery ?

OIC.

Battery + electrolytes = activate, i.e. is an uncharged battery
Battery + electrolytes + charging = formation process, after which a fully charged battery is ready to be install into vehicles.

Correct ? Means all batteries must undergo activation process and formation process before it can be used.

If taking the word activate or activation by its meaning, what exactly is activated in a battery, when the electrolytes are poured into the battery ? Nothing right ? The electrolytes and the lead plates are still in its original state and not transformed to store electrical energy yet, correct ? If both of them are separated, they will still be in their original form. Nothing has changed yet. So how can the activate word be used ?

Dry charged ? I have never heard of such a thing before. Sounds exactly like what the motorcycle shops are doing.

Wait a. minute, which battery brand was it that went through the 4 steps ?

Thanks, bro. Ya, after 2 years of usage for sure not as good as new. Just wonder still can use or drag or not?
My past few Amaron is about 2.5 years, that also not totally out yet. On FB group most of the same car model use Amaron can last up to 3 year + that's why I was wondering should i change it now. Of course no harm to change early, just burn in pocket as battery now not cheap.

My is DIN55R, by the way, crank power still good. Crank once up. Maybe is high-speed starter?

Wow, that very good. My previous Amaron should be able to last 3 years, as starter problem, make me suspect is battery, so change it during 2.7 years.

Btw do you do any battery test during this 5 years?

Your battery dealer so nice, still will charge the battery for you after 2 years used.

Most of them will say, 2 years is about time to change already.

Amaron with Amara Raja or amaron johnson controls? if the later, expect it last longer. nowadays with Amara Raja, quality drop a lot already

Wow your Amaron battery let idle for 2 years in the Vios during Covid, could still be reused upon your return ? Impressive.

Unfortunately for me, clients who leaves their Century Battery idle for extended period, when come back the battery will suffer some kind of damage as the vehicle will most certainly drain the battery. Everyone knows lead batteries must be kept in a high state of charge stall times for it to lasts long but you are saying your Amaron battery left idle for 2 years could still be use. Hmmm

Your Vios didn't drain the Amaron battery at all for the entire 2 years of unused ? It was "flat"

So Vios 13 years

1. Toyota 'Battery 4 years
2. Toyota Battery 4 years
3. Amaron Battery 5 years (2 years idle)

wonder what's the SOH of this battery

Boss, which model is your Vios ?

Just for record:
I just change my Amaron Pro DIN55L battery yesterday (I bought from batteriku on 1 July 2020) which mean 4 years 6 months. The longest battery life so far. Had run for 90k km. Worth it I think.

I change it because battery health not good anymore. If still use maybe can tahan another 1-3months.

Batterihub & Bateriku will give 18 months warranty if u go for Voltec & Astra respectively. Some sort their main product.
If u want other battery, also they have. But of course they will sell with higher price.
Amaron also still give 18 months warranty.

After using Amaron Hi Life for 5+ yrs (almost 6), finally it gave in, as I was away for a month, the battery sayonared!

This time around, bought Camel, to try it out. Hope it last as long as Amaron!
