found this reply to the AGM/Recon question on a jag forum

Recond program is developed only for flooded batteries (including EFB), to remix the flooded acid inside.

and so on

Thanks Elliot for finding the information from CTEK :D :D

It is almost the anniversary of when I bought my CTEK and did what I thought was helping the battery, so no more reconditioning until I hear differently

I normally wait until the start stop no longer works then put the battery on charge. Most of the time I turn the start stop off but I let it run once a week when doing short trips and perform a battery check the easy way :lol: . Nooo stopie, low battery!

CTEK connected directly to the battery. That way there is no sparking from using the alligator clips and so much easier than hunting for some other grounding location. IN the past there was always the chance of an explosion (or at least a loud bang) from gases from the lead acid batteries and connecting to a remote ground made sense as does it when boosting a dead car.

I have been using a Schumacher SC1319 Battery maintainer to get around the consistent "low battery" warning I get. I let LR Toronto know as we bought this vehicle as certified pre owned with only 24K on it, and it started almost immediately. With COVID the SUV is parked all week, and at this point it will barely go two weeks without needing a charge. I have to assume there is something wrong somewhere.

I have been connecting the positive to the battery and the ground to the LR recommended engine mount on the passenger side. It just looks easier than trying to get at the battery negative. The problem is so bad at this point I have considered put a couple of 8 gauge terminals down to charging posts under the front end so I can just pull it in the garage and connect the charger without even opening the hood.

So far this is the most disappointing part of the car.

There was a software fix. My start stop never worked (wife very happy) on a consistent way,unless I charged all the time. Now when I use the start stop it works 90% of the time.

I have wired directly to the battery. I wonder why owners listen to Land Rover as to where to put the connections as most of the trouble seems to be with their electronics anyway.

The ctek has an adapter cable that can be left in place all the time, does the Schumacher have one?

It does, as you can switch ends, I never really thought about that. To date I just take the front two plastic retainers off and tip the cover up to get the positive lead. I assume if I take the cover right off I can position them better. I believe the Schumacher came with one adapter that has rings terminals so I can really affix them permanently.

I hope when this all clears and I can get it in for service the software fix can be applied. I do find this car has more things on when its "off" than anything I've driven. Today I went for a 20 min drive to pick up dinner, 60 km/h average, it was 15C out and I didn't have the heater on. But on parking I can hear a fan running for almost 5 mins in the dash. That's probably helping things.

I did let LR know right away so at least its on file when I go in.

From CTEK:

With stop-start technology becoming increasingly widespread, the new MXS 5.0 model now gains a dedicated mode for AGM batteries commonly used in this type of vehicle. It also gains multi-mode functionality (denoted by the red mode button), meaning it's now possible to select AGM and RECOND charge profiles in any mode - so you can run a recondition cycle on a smaller battery, or optimally charge a small AGM to the correct voltage.

Re Battery charging. Yes the manual does say remove the battery from the car when charging, to prevent confusing the battery management electronics. An alternative to removing the battery from the car, is to disconnect the positive terminal from the battery and insulate. Apply the battery charger directly to the positive and negative posts of the battery. This prevents the charging current from flowing through battery management shunt connected in the battery negative wiring. What you will have to do when charging is complete and the positive terminal re connected to the battery. Is to reset the windows and blind settings. This is easy to do and described in the manual, it entails cycling each window and the roof blind through an open and close cycle.

During the lockdown, my car has developed an issue that the auto stop/start has ceased to work. For a 2 month period from early March to early May, when we were only allowed to make essential journeys, the car only travelled about 45 miles in total and I was not surprised that the auto stop did not activate, even when the engine was up to temperature. By late April, the red warning, battery low - start engine started appearing. Short journeys did not add sufficient charge to remove this warning and items such as the electric tailgate stopped working if the engine was not running. I rang the local dealer and asked if I could charge the battery or if I needed to drive a longer journey. The advice was:- " No problem in putting a charger on the battery, using the positive terminal on the battery but using the negative chassis connection point indicated in the handbook and not the negative terminal on the battery. In no circumstances disconnect or remove the battery as the car will require a full re-program". I explained the type of charger I have, a charge/condition unit retailed by Halfords and was told that was fine". I charged the battery without any problem with everything functioning as normal. However, following a 150 mile round journey late last week the auto stop/start system is still not operational. Any ideas?
