For new models Mazda is different right
They use those smart stop feature right?
Like new cars vezel harrier Sienta all use similar new battery?

Different from those like vios picanto civic?

Hi there, you are right.
Mazda calls their Start-Stop technology "Idling Stop or i-Stop".

Recommendation from manufacturers of cars with Start-Stop engine is to use EFB (Enhanced Flood Battery technology) batteries. These batteries are an "enhanced" version of the standard Lead-Acid battery and is designed specially for cars with Start/Stop engines. Reason is that they have thicker lead plates and provide for better cyclic stability so they have a longer lifespan of recovering from deep discharges (ie. < 12V).

Older cars without Start-Stop engine uses the standard lead-acid car battery. These days, most of these are maintenance-free so there's no need to top up distilled water.

There's a very nice write-up here if you are interested to learn more.

PS: FastFix carries EFB batteries.

Bro can share what is the life span of EFB battery and cost of it?

AGM, EFB and SMF (sealed maintenance free - conventional) batteries are all marketed as having different design and properties. In order to justify the cost differential of 50-100% extra compared to SMF, they all claim their batteries are good for xxx start stops. So logically the lifespan should be longer and a longer warranty given. But no no, the warranty period for AGM, EFB and SMF batteries destined for all gasoline engines is the same.

To make an AGM or EFB worthwhile, it must last 1.5-2 times as long as a normal SMF battery, because these batteries cost this much more.

If installed in a normal non start stop car, AGM batteries must last at least twice as long as a SMF battery. This translates to around 4-6 years lifespan, since a normal battery only lasts 1-3 years in a normal car. In actual fact, even normal batteries can last 4-6 years in a normal petrol car. But its very rare.

Conversely, when a normal SMF battery is installed in a start stop car, its life span should be shortened. But in real life, the life span of a reliable SMF battery does not differ much from an AGM or EFB battery. This is something u can test out yourself.

So in real life, AGM and EFB batteries do not make any economic sense.

There is a false marketing commonly used. Many manufacturers claim their SMF battery can last 30,000 cycles. If that was true, most people would be able to install a normal SMF battery in a normal car and it should last almost the entire duration of the COE. 365 days x 10 years x 10 start stop cycles a day = 36,500 car engine starts. But most of the time, our lead acid batteries - regardless AGM, EFB or SMF - fail completely way before that.

Thumbs up ,well explained.

I am not sure that an AGM batt cost 50% more than a reputable SMF equivalent.

I got a 74ah AGM for $250. The SMF is about $190 to $200.

The 74Ah AGM is installed exclusively in a continental car with start stop such as audi, vw, mercedes and bmw. If your battery failed prematurely, I am guessing your ride is either an audi or vw.

You have to state which make, model and manufacturing date of the SMF and AGM batteries you got, and whether it was installed in the same workshop.

Your SMF battery price is on the high side, and the AGM price is on the low side. If you indeed had the SMF and AGM batteries from the same brand and installed in an outside non agent workshop, there is a high chance the workshop passed you an old stock AGM, which could already be 2-3 yrs old, and probably not in a good shape.

This scenario is not made up. It actually happens. AGMs cost alot of money and are heavier with slightly higher Ah and CCA ratings. But most people find them too expensive and wont bother unless it was installed free under new vehicle warranty.

I think e weather in singapore is killing our battery my overseas vendor told me they only change their car batt once every 4-5 years and is unheard of that people keep changing battery every one to two years

Cold weather make battery drain faster.
My personal experience is HP battery not car, fully charge ald, use for a while only, percentage drop dramatically.

Yes it is - our heat is the reason why our car batteries die so fast.
In fact, every increase in 8°C in temperature causes the battery to half its life (Source: BatteryUniversity). Given that Singapore's average year round temperature is close to 30°C versus <15°C in US/Europe/Australia - our car batteries last an average of 18mth only.

One clear example: most car batteries comes with only 12mth warranty in Singapore. The same battery is likely to come with 3 (or even 5!) year warranty elsewhere.

The other example is that some continental cars' (BMW, Merc) batteries last for 3+ years even in Singapore. Why? Because the batteries are located in the boot (and not near the hot-hot-hot engine!).

You are right! This is the reason why - in cold countries - many people's cars can't start. However the real battery killer is heat (..and vibrations).

And also - the technology used is different. For mobile phones, it's lithium-ion and for cars, lead-acid. Unlike mobile phone batteries, car batteries are not "deep cycle" batteries, so they should be kept at full charge (almost) all of the time.

Its distance.
Sg all city driving.
discharge more than charging.

Sent from SGH BLK 9 using GAGT

Car batteries typically require 20min of highway driving (60km/h+) to fully charge. Many people who drive daily short distance ( <20km) do not allow their batteries to be fully charged. As a result, the battery never gets the chance to be fully charged. This results in "sulphation" (Source: BatteryUniversity) which results in a shortened lifespan for the battery.

To reduce chance of sulphation, a car battery should be fully charged on a regular basis (once/week?). Maybe can drive from one end of PIE to another - on the weekend. :D:D:D
