Jazz battery charging

[n.jazz]

HI , so as a very low mileage driver, the jazz has not been out more than once every 2 week and even then its for 2 short  town runs (out and back, stop inbetween). Yesterday instead of starting it just gushes machine gun like clicks and the dash lights were flashing at the same pace. Online stories pointed to the battery or a loose connection and today when the breakdown guy  hooked his portable power pack to the battery it started like a dream. I quickly bought a CTEK MXS 5.0 and has  been charging for 2 hours with 4 amber lights on so far out of the eight charger indicators. I am running the charger on the normal  'CAR' mode as opposed to the other 'CAR AGM' mode, as I think the Jazz 3rd generation has EFB type battery rather than AGM.  So The questions I have are;

 1) Was it OK to have connected the crocodile clips directly to the battery points without unbolting and lifting off the terminal connectos first?  AND

2) should the black Crocodile clip been connected to a metal chassis point instead of direct to the negative battery terminal? AND

3) Is the 'CAR' mode up to 14.4V 5A the correct settting on this charger for the JAZZ compared to the 'CAR AGM' mode with  up to14.7V , 5A ?

Thank you for taking the time to read.

Not certain the difference between normal lead acid and AGM as far as charging is concerned,

No issues at all with connected to the terminals on the battery posts,

Might be worth checking for corrosion between the posts and terminals clamps,

Leave it on charge until you have all greens

When using the charger the positive cable should be connected to the battery post but negative cable must be connected on the part after the battery monitoring sensor. This is well instructed in manual.

Your Jazz doesn't have an AGM battery, so you should use normal charging mode.

I also think you should change your route and try doing 10 miles each way, it's better for the engine, gets properly warm and will no doubt do your battery a power of good. Run the air con as well, leaving it on will do no harm, in fact it will help keep the system seals lubricated.

Thank you TnTkr , Can you please explain where you mean by connecting the negative cable to the 'part after the battery monitoring sensor' ?

I tried to take a picture, but the file size is too big for the forum limit.

It is the L-shaped metal part on the engine side of the small black box next to the battery post. Black earthing cable is crimped to that part.

Thanks againTnTkr,
 I see the photo now, I just moved the negative clip to the green 'Si' part from the Red 'No' part, So the Battery Monitoring Sensing has lost track of the 4 hour charging so far but at least it should start to register charge from now on. Anyway I always disable the Stop/Start function , as two qualified mechanics told me it uses  battery charge and in the long run shortens the life of the starter and battery , Wear and tear is logical  to expect with any  repeating mechanical/electical procedure.
