Bro, what Bro. Therain01 mentioned is correct. Just read slowly and you will be able to understand what he is saying.

The term Maintenance Free Battery is meant to mislead. The correct term is Low Maintainance Battery. I believe the term Free was adopted purely for marketing purposes.

Thanks for the clarification. Some low maintenance battery does lost more electrolyte than other though. Yokohama MF gold for example did a lot of mess on my car when it spill during the trip coming back from Cameron, while the Panasonic wet battery does not require top up throughout its one year service (short life though).

Agree wholeheartedly.

When I was given the Yokohama Gold MF Series for testing purposes, I was shocked to that it was "glazed" with signs of gunk. Shocked because after all the positive reviews from almost everyone, this is not something that I would expect.





I shouldn't have dry brushed to removed most of the gunk away. It would have made better pictures I guess. Just like you've said it's a mess.

On Wednesday a friend visited asking about the battery indicator on the instrument panel. When he wanted to leave his Viva couldn't fire up.

Upon checking the electrolytes were low, so added battery water & jump started it from a bigger capacity battery.

Halfway on his journey, his Viva stalled while driving ! He couldn't believe it when I told him that it was possible. So met him halfway and gave him another battery for him to continue his journey home while I took his 8 month old battery for charging.

Reffixed the fully charged battery by next morning. On the same day he was told that the alternator had malfunction too.

Conclusion ...

Yeah battery indicator turn on so probably alternator is bad. Check the battery if voltage is above 13V when engine is running. Anything less than 13V then alternator is bad.

Mine battery have Powder stuck to positive post.
Is this undercharged or overcharged?
Have been using a refurbished alternator after original kong.

Is Bosch brand battery ok? Shop quited 180, if trade in old batt 160. Also, are there fakes?

the battery pictures

It sure doesn't look like any of the Amaron, that's available here.

of course, in year 2010 i never heard this brand..

What I meant was this White coloured Amaron's casing is not found here.

Even the font type for Amaron is completely different from the Green coloured Amaron's casing that available here.

The different coloured casing may change for different markets like Varta but changing the type of font of the brand name ? So which is the correct Amaron & which is the fake ?

If there's a warranty for the Bosch battery & that's supported with an accompanying Warranty Card, who is to say that it's fake ?

As to whether Bosch battery are good or otherwise, no comment as I have never heard of Bosch before. So it is with Energizer battery that I've recently come to know.

That's corrosion from the hazardous chemicals inside coming out in the form of gasses.

Clean the terminal posts & use terminal protectors. Plus check the electrolytes levels frequently now onwards.

By the way, what brand of battery is yours ?

well, i cant be sure of that.. but hardly known there's a fake AMARON battery.. so far never heard this kind of case here in Malaysia.. but what we know, all AMARON battery made in india right?

That's what the battery player(s) would like all of us to presume, from India 🇮🇳 and that's it.

I recall my research into Amaron and I don't remember seeing Malaysia listed as 1 of the countries batteries are exported to; but then again Amaron website may not be up todate that time.

But with your picture and a different font type on their brand name, now this is where it gets really interesting. LOL

I thought it has a big presence here

https://www.amaronmalaysia.com/

and Tecxus Marketing is the main distributor for Amara raja

Powerzone is also from them

Well it is commonly assume that overcharge will cause white powder at positive terminal. Many were claiming such, probably due to positive terminal side was heating up when overcharged. As far as I concern, it's all come to the quality of the battery housing. Bad housing at terminal are causing leak after some time.

Answer to your question, no I can't give the definite answer and I doubt there's absolute answer out there.

Here is a good explanation on it

https://jalopnik.com/heres-the-deal-with-th...r-ca-1796168791

Positive terminal
<<
Since that picture right above is of the positive terminal, let’s start there. The greenish-bluish crap is likely copper sulfate that’s been exposed to a bit of moisture. This is formed when the copper in the terminal clamp reacts with the lead in the battery terminal, helped along by the transmission of electrical current and sulfuric acid from inside the battery, and maybe seeping out a bit from various seams.

The chemical reaction looks like this:

Cu (s) + 2 H2SO4 (ℓ) → CuSO4 (aq) + 2 H2O (ℓ) + SO2 (g)

This copper sulfate does not conduct electricity very well, which is why battery performance will degrade (and, with that, you’ll get other electrical issues), and why it’s a good idea to clean this stuff off the terminal. Baking soda and water are good for removing the corrosion, because the baking soda will neutralize the acidic copper sulfate.

>>

Negative Terminal

<<
Now, if you have white powdery corrosion around the negative terminal, that’s different stuff and is there because of a different cause. The white powder is the result of a process called sulfation, and it’s usually caused by a lead-acid battery not being charged enough.

This can happen if your car is used for mostly shorter trips, especially if you have a modern, electricity-hungry car. Modern cars tend to have a lot of ancillary electronics that draw a good bit of current, and if you mostly drive in short hops, the alternator may not be running long enough to properly recharge the battery.

Personally, I normally oil the terminal with wd40, there is a oil ring protectant washer thats being sold

Bad battery housing, that I agree.

Another common flaw with Low Maintence (MF) Battery is the screw caps. I personally suspect that it's this too simplistic design is making it all the more easier for gases to escape as compared to the Flooded Battery designed screw caps.

👍🏻👍🏻👍🏻👍🏻👍🏻



I don't like cleaning things that are hard to clean, so I would rather prevent them from happening in the first place.
