What Ctek Mode?

I've just bought a Ctek MXS 5.0 to maintain my battery, but I'm not not sure whether I should use it in car mode or AGM mode.
The fitted battery is an AGM type I believe, but do I connect the Ctek in car mode which it says is suitable for most AGM batteries, or should it be in AGM mode?

I also bought one recently and use it in "Car and AGM mode" as it is an AGM battery fitted to the XE. I use the positive and negative lugs provided in the engine compartment. Do not connect it directly to the battery, unless you have disconnected it from the car, as you can damage an electrical component which is connected directly to the battery. Once you have connected the leads and turned it on, press the button on the charger until both the "car" and "AGM" lights are lit.

As said by Bazzamf, but you can connect to the battery +ve and a the negative to a stud on the boot floor near the rear lights. I have connected it to the battery directly without problems proven by numerous checks by the dealer in early days of 2015&2016. I would suggest using the RECON stage as well for one charge up then just CAR and AGM for future charges. I use RECON around 5 times a year as the car does not get enough use and my S/S seems to be behaving 90% of the time.

How often do you charge your battery Vespa? I have used the recon three times as well as charging the battery in between times, in the hope that the s/s would work, but to no avail, so it will be back to the dealer shortly to sort.
On the side, with a name like Vespa, did you ever have one?

Vespa = wasp and used several times on various websites. No, I have never owned anything on 2 wheels with an engine as my dad wouldn't let me have a motorbike but wasn't too bothered when I was out on my racing bike coming down hills in Wales at over 50 mph when racing.

The charging I give mine is about every 10 days or so just to keep the battery in good nick if I don't use the car much. If I am out and about I don't bother as the S/S works OK. I have realised that the VW I had lost battery power also but as it didn't have S/S it wasn't noticed until the info screen warned me to start the engine. Sadly my car doesn't get enough use as my wife is unwell and still recovering from a 3 week hospital stay last year. She is seeing more specialist Dr's again in Sept. and she takes what seems like hundreds of pills at the moment. This restricts the car use as we don't go out a lot anymore. Hopefully we will get out a bit before winter sets in. Just as a note I have Hospitals set in the satnav just in case.
Give your car a couple of recon charges in a couple of days as this really did boost mine earlier in the year. I did it twice in one week and all seemed better with the S/S working for longer.

As mine's parked on the drive, I found it easier to connect under the bonnet to the jump start points. Bringing the Ctek unit out by the wipers. That way I can shut everything and single lock.

I think it was May when I last did a double recon in a week and this topic made me decide yesterday to charge and recon. The charge took about 2 1/2 hours and the recon was the full 6 hours. The car was taken out today to visit the Dr's and the S/S functioned every time. The car, for some reason, seemed livlier than normal. Probably just a coincidence.

I did a recon yesterday, (the forth I've done over the last month) leaving the charger on over night. I used the car this morning and after stopping several times with no activity, it surprised me by the s/s working once all morning. Perhaps if I do another recon it might work twice. One lives in hope. :roll: However, I think Jaguar need to rectify it for me with a new battery perhaps?

I drive a 2012 Focus at work and my previous car, a Golf, never had an issue with stop/start. The only time it didn't work was if the aircon was needed on to bring the temperature down.

Jaguar obviously have fitted batteries with not enough amps for the electronics in the XE and don't want to do a recall. People on this forum have said that the issue is rectified if you buy a 95ah battery. If you type in your reg to any site that sells them, that's the size that comes up.

I've only had my XE since 17/08/18, supplied new and the stop/start hasn't worked once! It's plugged in as I type to a Ctek.

As a matter of interest Pete321 what size battery is in yours, I am waiting until I have some spare time, and then, I am going to fit said 95ah, and then give JLR some stick if it cures issue, shouldn't be down to me to buy my own, but dealer has said if it passes test, then they will not change it. So is test itself faulty?

Mine's 80ah. Jaguar must realise the amp rating is too low, but don't want the cost of admitting it.
The dealers will never replace the battery if it recharges ok and passes the test for holding the charge.
From what others have said, a 95ah battery fixes the problem, but like you, I don't see why I should have to pay to replace what is an inadequate part.
All the batteries suitable for the XE 2.0d on Eurocarparts are rated at 92ah to 95ah.

Tanya Batteries (great company to deal with) recommend this one.
Not a bad price and it gets good reviews, including some from Jag owners.

That's a good price I am looking at around ÂŁ200 from Halfords, I will take a look at these

I have a CTEK 5.0 as well and use it about once a week and if going on holiday leave it attached to the car whilst away. I have had a DIN socket fitted into the car boot and so it's extremely quick and easy to plug in the charger.

I understand that the recon mode charges the battery at a higher voltage, making the battery gas and bubble stirring the water and electrolytes, but if the battery is in good condition should be only used 1-2x a year.

The recon mode is recommended to be used at least twice a year. For cars that get little use, like mine, I do it around every 2-3 months and so far the battery is behaving much better with S/S working even with the aircon on. I reckon that the 85Ah battery is not suitable for the car and the only way to make it work correctly is to recon regularly. As I intend keeping the car I am considering fitting a 95 Ah battery at 5 years, when the original will be past it's best and suitable as a back up battery.

I did a recon AGM charge, but still no stop/start. After reading the many posts on the forum regarding the 80ah battery fitted by Jaguar, I've order the 95ah Enduroline battery from Tayna. Shouldn't have to, but Jaguar obviously aren't going to admit to the problem.
With Tayna's quick service, should have it by Tuesday.
I must admit though, it doesn't seem too straight forward to get the battery out from the boot!

From what I have read about battery changing on the XE you will have to do a lot of resetting of various things unless you have a slave battery connected to keep the car thinking it is still active. (windows, EPB, possibly gearbox and a few other items)

I don't understand why people are so worried about disconnecting their batteries. I disconnected my battery to charge it the very first time and the only resets necessary were the windows and the radio, which was very easy to do. In fact it is easier to do than connecting a slave battery. By the way, I now charge my battery using the lugs in the engine compartment, it's far easier than disconnecting it.

Hi Bazz, did you lose nav system favourites etc?

Hi Repairman, to be honest with you I don't have any favourites on my sat nav at the moment, so I can't answer your question.
