CTEK on EFB Charging

[Y_K]

Have this reply from CTEK support:
======================
Hello,

Yes, the MUS 4.3 Polar is designed for all types of 12V lead-acid batteries including EFB.
Use your charger in the normal "car mode" when charging and maintaining 12V EFB batteries.



Med vänliga hälsningar/Best Regards,

But it doesn't have a EFB specific mode.

 

[gathermewool]

No, thank you!

 

[Rand]

Since its a "flooded battery" does it even need a special mode?

 

[skyactiv]

My take is that EFB batteries have a more forgiving charging acceptance than standard flooded batteries.

 

[meep]

EFB does not have any differences in chemistry … it’s changes to increase internal surface area. Therefore the same voltages apply.

that said, I’m not entirely sure why the agm’s need the higher voltage, unless it is to counter resistance to striation through the damp mat, versus free-flowing electrolyte.

None exist...yet.
But I believe the point is (depending on the charger manufacturer) most claim you can either use the AGM or flooded setting fine. The recommendation varies with manufacturer, so appropriate to ask.

just lookin for my 8 YO interstate in my 2011 Fronty they PUSH AGM's $$$ but it will get another flooded LA batt prolly an Everstart from Wallys Prolly made in Reading Pa!!

Not needed.

Battery types – Lead acid, AGM, EFB

Car batteries have greatly advanced over the past years. A new generation of starter batteries uses EFB and AGM technology.

EFB batteries are an optimized, higher performance version of the wet battery. The abbreviation “EFB” stands for “Enhanced Flooded Battery”. Here too, the plates are insulated from each other with a microporous separator. Between the plate and the separator there is also a polyester scrim. This material helps to stabilize the active material of the plates and extend the life of the battery. EFB batteries have a large number of possible charging cycles and provide more than double the partial and deep discharge performance in comparison with conventional batteries.

EFB batteries are often installed in vehicles with simple automatic start-stop systems. Due to their superior performance batteries with EFB technology are also increasingly used as replacements for conventional lead-acid batteries.

Advanced and Robust batteries are generally staged as the “Best” of a Good/ Better/Best battery line up. Their identifying features are generally that they are of higher capacity and/or have thicker positive grids then the standard products. These Advanced/Robust batteries are designed towards excelling under the standard Starting, Lighting and Ignition (SLI) requirements, which are governed under industry standards SAE J537, J2801 and /or EN50342-1.

EFB batteries, on the other hand, are designed to meet the standards for SLI batteries, plus the additional requirements for vehicles with the capability to automatically switch off the engine during vehicle operation either in standstill or moving (“Start-Stop”), as well as the capability to recover braking energy or energy from other sources. EFB batteries are designed to meet the requirements of a higher set of standards governed by SAE J3012 and/or EN50342-6. These two standards include demanding partial state of charge cycling and dynamic charge acceptance requirements that the SLI requirements do not.

Enhanced vs Advanced and Robust Flooded Batteries: What Does It All Mean?

EFB batteries are designed and manufactured differently and held to higher performance standards than Advanced or Robust SLI batteries.

EFB vs. AGM: What Will Power our Cars in the Future?

While AGM batteries have handled the demands of modern automobiles, EFB technology surpasses AGM in critical areas such as battery life and heat tolerance.
