Recharging a flat battery using the Ctek mxs 5.0

[Duvetday]

I'm about to embark on fitting a CTEK charger using a comfort lead.

I have the link to the useful guide somebody did here.

Only question is...at point (3) are they talking about disconnecting the negative terminal from the battery ?, or are they talking about disconnecting the negative black cable that is attached to the body of the car (see phot above point 3 in the guide).

Moreover, did other people completely disconnect the batteries main positive and negative connections before doing anything else for the sake of safety ?

No need to disconnect the battery just be careful when you're fitting the CTEK leads. Do the positive first, and for the negative I used the boot floor earth point that the battery lead is connected to - just hold the battery cable down firmly to maintain contact as you remove the nut to fit the CTEK black lead.

Thanks.

I'm struggling to get hold of a CTEK charger right now.

In the meantime is there any reason I couldn't just attach a normal battery charger to the positive and negative points indicated in the link ?

So ...positive to bus bar and negative to the chassis ?

Should be fine. The CTEK (or equivalent) is recommended as people can leave it connected "for ever" while the car is not being used.

Jaguar recommends removing the battery to charge in case the charger fries any of the car's modules. If you do remove the battery, make sure the boot is unclosable or you'll struggle to reopen it.

Resurrecting an old thread for some advice. I've had a low battery warning so plugged in the CTEK MXS 3.0 using the connector connecting to the busbar as per the helpful info here and on AGM mode.

It's been on the half-battery amber light since Friday afternoon. The battery wasn't flat so curious if anyone has any guidance on how long it should take to go green. I'm aware that the CTEK is more of a long term maintenance type charger rather than a traditional charger but I had thought it would have charged over 48 hours

Thanks in advance

I'm probably asking something that's covered in the thread.
Is it possible to place a battery maintainer on the points under the bonnet instead of geting to the physical battery in the boot ?
thanks

Here is the charging sequence/times. MXS 3.0, Typo maybe is it a 5.0?

Yes it will charge through the points using the charger’s clamp fittings.

How old is the battery? Not sure what you mean by amber light - is that the CTEK connector with green, amber and red lights? My battery is over 7 years old and I get the green as soon as I connect the charger, and it never takes longer than "overnight" (~12 hours?) to get fully charged.
