A further thought. The short wires on my power bank are quite thin.   10awg  and 200c heat rating.  The negative is only 10 cm long, the positive  20cm long.     10awg wire is rated at 30 amp continuous     but can probably take a lot more amps for a few seconds before  burning out. 

These power banks  make the claim they can start a conventional ICE engine with a starter motor. Thats a lot of amps.  It would need to start in a couple of seconds I think or would burn out.   It might only be possible if the main battery  still has enough charge  to supply most of the amps.

But I think I read somewhere that  hybrids only need about 30 amps to power up their 12volt  systems. And only  needs this much because it needs to power a heavy duty switch to bring the HV battery into use.  (which actually does the heavy lifting of starting the ICE.  )     
So for a  mk4 Jazz the powerbank would never  need to provide 200+  amps to crank the engine. Just 30 amps or so for a couple of seconds  . I think it would work, although I have never needed to put it to the test.   Has anyone on here ever used a small power bank to power up a mk4 with a flat 12v battery? 

I'd be interested to hear the thoughts of experts.

Here's a link to free workshop manual for your Mk1 Jazz, the website has useful info

Thanks c.lday44; that little screw is a bit difficult to handle but I managed it.

Good point. The universally recommended method of jump starting is to connect to a good earth/ground point , remote from the battery to minimise the chance of a spark igniting any explosive gases from the battery. 

My little cheap and cheerful power bank comes with very short jump leads, spanning only about 30 cm (12") in total. Long enough to connect directly to the Jazz battery terminals ,(and most but possibly not all, larger batteries. ) Or  alternatively the red lead to the battery and the black lead directly to a nearby bolt on the engine block  .  But either way all connections would be made very near the battery.

In my ignorant and reckless youth I often jump started  directly to the battery terminals, and lived to tell the tale.  And that was in the days of topping up cells.     

Is there still a risk of explosive gases from a sealed ,maintenance free battery?   Or is the recommended procedure  just to be on the safe side for any type.     

I always  carry some conventional jump leads, as a belt and braces approach, so could if necessary extend the negative lead of the power bank using one of those. 
As far I can see, none of listed batteries by Tanya is good for start and stop, the only matching parameter is size.
Jazz GK series wants one of the following EFB battery:

Yuasa YBX7053
Banner 55515
Napa AFB158N
Enduroline 048EFB

Maybe there are some other models fitting in the slot, I don't know, would be great adding them to this post.
Using a non EFB or AFB battery (AGM or standard lead-acid) will affect the battery lifespan.

Thanks for this really useful post, I'm also in need of a new battery. Can I just check with you if the above batteries are suitable for my car as well? We have a 2018 MK3 1.5L Sport. I'm not sure if the 1.5 Sport requires a different battery. Also, do you need to register or code the battery when replacing it or is it a straight swap as you do with a normal battery?

Thank you!

Removing the cat will make no difference to the sound but it will cause all sorts of problems with your engine running. The ECU depends on signals from the sensors mounted on the cat.

Hi just a quicky. The other day I went to unlock the car and the key fob only half did the job, it started to operate the locking but not completely. I checked the battery and it still read 3.17 volts, but suspect it's that which is the fault. The other key fob works fine.

Have ordered a couple of Energiser ones from Amazon (not the 'cheapo' ones as they sometimes don't last long.

Can you tell me; is it just a case of just changing the battery, or do you have to do some kind of programming from the car?

Thanks in advance, Mike.

P.S the car's only done 70K now and found it to be very reliable.

I replaced the batteries in both of my keys just last week, also with Energizer batteries. One key was completely dead and the other may not have been far off. Both work perfectly now, no coding.
