Charging battery

[WhiteBear]

I would like to permanently install a charger under the rear seat, there seems to be enough space. I have ordered the dual battery. The charger should be connected to the ctek smartpass to charge both batteries hopefully.

The car sometimes stays at the garage 2-3 weeks. My Defender does not like that so I always connect the charger when the car comes into the garage.
What do you think, will it work that way With the Grenadier?

is there any reason the terminals under the bonnet couldn’t be used for charging with a smart charger. Surely if they are there for jump lead connection they should work for other charging methods. Just a guess as I don’t really know what that positive post under the bonnet is designed for other than jump starting.

No in theory, although I don't know what clever electronics Ineos have in any circuits that might prevent it. It would be nice to have a diagram.

I charge my D4 through the tow ball electrics via a Ctek charger

Do this with my Defender and it seems the best/easiest way. Will swap it over to the Grenadier; hopefully the CTEK is clever enough to show any faults or issues with doing it this way.

Thanks all for your comments/advice. Has anybody successfully completed a charge cycle ie the charger unit going from a couple of lights to the full panoply to indicate all charged and now at maintenance level?

My CTEK charger (a basic model) is connected and has got to 3 lights but seems to have stalled at that for the last few hours. I will keep it on overnight and see what happens/changes but am beginning to doubt that my charging attempt is working as I had hoped

Exactly which model have you got?

Does that mean passing a mains voltage cable somehow outside the vehicle?

Yes, of course. I have a socket for the 230V installed at the rear at my Defender.

I did a full maintenance charge on my batteries yesterday using a Victron blue smart 10A smart charger, the one thing I didn’t check though was whether this charged both the starter and auxiliary batteries. I just laid the power lead over the top of the rubber seal that seals the bonnet. I thought the bonnet had shut properly as seemed firm but could not lock the doors and leave it on charge. That bonnet seal must be a real tight fit as I couldn’t get it to slam shut enough with the cable there to enable me to lock the doors. Eventually I laid the lead to come in under the bonnet next to the windscreen and central locking worked fine.

Here are a lot of opinions what’s the best method of charging, to find out the right answer, I wrote an Email to Moll batteries. Here the Answer:

Bei der EFB-Technologie handelt es sich um eine Nass-Batterie, deshalb auch in diesem Modus laden. Generell gilt es, für das externe Laden der Blei-Säure-Batterien einen Ladestrom von mind. 10 % zu verwenden, da zu niedrige Ladeströme die Ladezeit verlängern und die Zyklenlebensdauer der Batterie reduzieren.

The EFB technology is a wet battery, therefore also charge in this mode. In general, a charging current of at least 10 % should be used for external charging of lead-acid batteries, as charging currents that are too low extend the charging time and reduce the cycle life of the battery.

For me means my CTEK MXS 5.0 is not strong enough and a MXS 10.0 is needed.

Thanks for following up with Moll. I use the same charger as you so I guess I’ll be looking at an upgrade too.

Also de-bunks the raison detra of all smart trickle chargers that charge at very small currents. So it is the comments and wisdom of smart trickle charger manufactures vs the comments and wisdom of Moll batteries

I will jump to Victron, 15A, bluetooth/App, and nearly same price as CTEK 10a

You’re right, but I think the producer know what is the best for the product….

The question is did Moll say : Charge with 10 % or charge with max 10 % to the capacity to the battery.

 

[MarkH]

At least 10% of capacity, up to 20% is fine for lead acid.

 

[Lollo050968]

They say what I posted… I think they mean 10% of the capacity, and that is why I will jump to Victron 15A….

When I picked up my Grenadier the agent told me if I needed to do jump start, to remove the plastic engine cover and connect the earth jumper cable to the lifting hook on the front of the motor. Seem a bit odd?

 

[Lollo050968]

No, standard procedure.

That’s fine it’s a good earth connection also suitable for maintenance charge of batteries

Yeah I didn’t think you needed to remove the engine cover.

Can you clarify please the meaning of "charging with 10% of the capacity" in terms of "amps"?

Solid sturdy point that is unlikely to have any corrosion thus making a good contact.
