Charging battery

Logsplitter said:

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.

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

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

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?

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

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

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.

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?

That’s fine it’s a good earth connection also suitable for maintenance charge of batteries View attachment 7821860

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