Heating system is useless

[Skymark]

Smart alternators are controlled by an ECU to limit charging to a range as a part of emissions optimization

Seriously they should be embarrassed enough to fix this for all existing owners. What they have produced is an hvac system from a high school automotive class project. It’s pure ass

not HVAC but HAVOC system is what they delivered

I’m glad you’ve got your new order in.
I don’t think there is anything wrong with the batteries as supplied. I think the issue is when they are allowed to go flat especially if that happens a few times. Most batteries apart from Lithium will quickly be destroyed if completely flattened. Maybe your Grenadier was parked up along time before delivery or since and not had the batteries maintained?

If it is a lead-acid battery, doesn't matter if it is wet or AGM, small currents are killing them as well. That is due to the growth of crystals while power is taken out. High currents lead to small, fine crystals, low current (like ECU, smartphone loading, etc.) lead to large crystals.

These crystals are material which can not be used for power and they block the flow of current. When you charge the battery. the small and fine crystals are reverted very well. It is difficult to revert the large crystals. They may never go away and thereby you loose electrical active material, reducing the battery capacity and power thereby.

Another effect is, that when taking power from a battery both plate materials (lead and lead oxide) is turned into lead sulfate (which is reverted to lead and lead oxide while charging). That leads to physical stress in the plates and small parts can break apart, also reducing power and capacity. That an donly that is addressed by AGM. It keeps these parts in place, so they do not fall down and are lost for the capacity.

Thanks. Although I’ve read all about this stuff most of it goes straight over my head to be fair. That’s why I’m not a mechanic or technician.
Moll marketing blurb seems to think their AFB batteries are AGM in disguise . I know we don’t have AFB. but some form of enhanced EFB called EFB PLUS especially made for Ineos. There’s nothing to be found about EFB PLUS batteries from Moll

EFB means there is a labyrinth inside the battery lid to prevent water from evaporating. Because evaporated water needs to run a long way to leave the battery through the ventilation, it has time to condensate and flow back again instead leaving the battery. That keeps it working for an extended period of time.

That has nothing to do with AGM. AGM means that the acid is bound into glass fibre mats between the lead and lead oxide plates stabilizing them and thereby making them somewhat more resilient to low currents. But low current is not what lead-acid batteries (wet, AGM or gel) are intended for.

Thanks. Way over my head.

Thanks. Way over my head.

Most stuff on here is for me, I just use it to tell the dealer what needs doing or ideas for adding to the vehicle. All very helpful but I'm no mechanic.

Lynn told us they removed the aux battery for several reasons, including that the supplier is no longer making a part (ctek 120 I believe). If IA were to replace that part with another, the truck would need recertification/homologation which would be stupidly expensive for a system that that the aftermarket has provided better options.
