Need some opinions here regarding start stop car batteries.
Generally the two types of car batteries needed for auto start stop to function is either EFB or AGM battery.

EFB - enhanced flooded battery
AGM - absorbent glass mat

I won't go into the details to explain the differences but it is already known that AGM in general is slightly more superior to EFB.

Now my question is, given the same budget, would you pay for cheap less popular brand AGM batteries (rocket, camel) or go for the branded EFB (varta, bosch)?

Bro, what is your original battery spec. listed in your car or manual. If original is AGM type battery, EFB type battery might not be able to support for long term as it is downgrade from AGM.

Rocket brand is famous Korean brand used by a lot of Korean cars like Hyundai & KIA. If want cheaper some China brand AGM type battery already in local market but quality wise unknow. For me Rocket is quite reputable nowadays and my current ride is using it and no issue for almost 1 year now.

Original battery spec is EFB
That's why I'm considering AGM as an "upgrade"
But at the same time, I'm not sure if AGM is suitable to be placed in engine bay where heat is a problem

With so many different brands in the market nowadays, cheap unknown AGM brands can be priced almost the same as branded EFB

I assume your car has Idle Start Stop, to have EFB.
I found this article written by Varta:

QUOTE
When is a change from EFB to AGM recommended?


An upgrade to an AGM battery is always advisable if a large number of electrical consumers cause an increased power demand or if maximum availability for use is required. One advantage of AGM batteries is the fuel saving which is achieved with the effective operation of the automatic start-stop system – and therefore saving money. All consumers in the onboard network benefit from a good power supply, even during stop phases and also operate reliably under unfavorable weather conditions.

Since you said you are concern about "whether AGM is suitable to be placed in engine bay where heat is a problem"
If it were me, I would wrap the EFB battery with food thermal wrap. Yes. Food thermal wrap. Keeps the battery cool and keeps the heat away.

Branded battery only make your battery last a little bit longer. Its the heat which reduces its lifespan.

Depending on the car design also. Some car if electronics is a lot like Mazda, their EFB Q-85 battery also cannot last long. Max 1-2 years also KO.. doh.gif

So for this Mazda's case, an upgrade from EFB to AGM is recommended?

TS, that would be dependant on what is already under the hood.

If I were in your shoes, I would use the same battery same brand again before switching out for a different battery make and brand the next round. With the Law of Averages, you ought to get better results for comparison purposes, ceteris paribus.

On second thoughts, perhaps its better to go for good quality EFB batteries instead of low quality AGM's that lasts no more than 2 years. I read that somewhere.

Since good quality SLI batteries themselves are producing results, I reckon good quality EFB batteries should do the same, I hope.

Haha thanks for the advice but it came a little too late.
I went ahead and bought the cheap Camel brand AGM instead. It is priced slightly cheaper (20-30 bucks difference) when compared to Varta's EFB.
Now just have to monitor and see how it goes. Will update here if the battery dies prematurely.

See the employee review, seems they stress on good quality.

No worries.

I had no idea its possible for some cheap AGM's to be slightly cheaper than high end EFB batteries. 😨😨😨

Would be keen to know how your new Camel turns out. 😊

Bro., I don't know but reading the comment carefully, it appears that this marketing executive has lost a couple of accounts because of sub-standard battery quality that the rep is representing now. If its anything, they don't stress on good quality at all. Correct ?

On second thoughts you could be right, since the employee former company had better quality controls, the new battery company better stress on quality if they are to survive.

Partly due to market penetration strategy by offering attractive price, partly maybe due to the fact that camel has a battery plant in kuantan....

In today's Paultan thread :

EFB and AGM batteries

Cars with auto start-stop functions, such as the Perodua Myvi and Bezza Advance models will require higher-spec batteries that are designed specifically to cope with multiple start ups for the everyday drive. You technically can use a regular battery, but its lifespan will be severely shortened. For cars with auto start-stop, an EFB (enhanced flooded battery) is required.

Premium cars with both auto start-stop and regenerative braking functions, on the other hand, will need an AGM (absorbent glass mat) battery. This is a much, much more expensive type of battery, easily costing up to three times more than the price of a regular car battery. These typically last longer because they are built to higher standards, but again, just refer to the same battery model that’s already in your car, to be safe.

But there are clients who don't want to be safe and follow the proper SOP, instead they dictate that you follow their own individual sop instead. I had one even showed me the pictures of battery that came with a new car a NS40ZL, when my listing shows its a DIN55L for some weird model that I dont remember. One even told me these batteries are suitable for PV, I was like what ??? Now I no layan random calls, random calls get random stupid answers.

But they say clients is always right ! Says who ? Kaw guru 'teri ke, aku guru 'teri ? 'Teri viral. LOL Some clients like to live dangerously is what I have noticed.

Now I only take care of those who listens to my recommendations until we are like family members and I strive my very best to ensure their batteries don't die a sudden death. Ability to foretell its death like tukang tilik is sure fun. Life's too short to straighten out the hard headed. Better work with those who desires results. 😊

Hard for me to digest.

When one have to invest into EFB and AGM, just for fuel savings .

Lets take example: m42 EFB 60B20L rated at 40AH , CCA 400A
- which cost around Rm 280. Common for Myvi/Bezza Idle Start Stop

Q85 battery - rated at 65AH , CCA 660 , which cost at least RM 450 + onwards

Source: https://www.lazada.com.my/products/varta-q8...3165922361.html

Versus: Typical NS70L (Non AGM /EFB)
CCA 60AH CCA around 447

Which cost around RM 200+, not more than RM 230.

Bro., all I can say is if one wants to keep the warranty one has to follow the SOP accordingly. If one does not want the warranty any longer and knows exactly what is one getting into, then by all means but its caveat emptor.

most of these start/stop are for EU/JPY emissions tax...not fuel saving

my car I just disable start/stop even though using agm
