New Jazz - Questions

[coldstart]

A lot of emphasis on CTEK charger. These seem to be really quite expensive, is there a recommended model of this type or a more reasonably priced alternative?

Just make sure the charger of your choice is safe to use while the battery is connected to the car's electronics.
IIRC it shouldn't exceed a charging voltage of 14,5V!

You are right: CTEK-charger's are expensive - however, they have a track record of being very reliable.
(I have a CT5 Start-Stop charger myself and use it to occasionally recharge the Jazz's battery (more frequently during the cold season) and always, while the battery is fully connected.

So far - three years - and nothing bad to report.

Of course, there are other (modern!) chargers available at lower prices.
Just refrain from using an old transformer-based "clunker" on a modern car, while the battery is still installed!

Anyone used a CTEK permanently connected plug arrangement on the battery for their Jazz?

Looks more or less impractical for my 2025 Advance due to complete cover on battery +ve terminal.

I did

I used the optional lead with rings and bolted them permanently

It did involve cutting a small notch in the red plastic cover for the lead so I could clip the cover back into place

Did the same on battery terminals of 5 Civics, the Jazz and the E with the trailing wire plug held on velcro under the bonnet. Have used a Maypole (cheaper Ctek clone) and Lidl intelligent chargers for years with no problems.

The red cover is easy to flip up with your finger . Easy to connect a lead with ring.  Rather than undoing  the nut  the small bolt  is long enough to just add a second nut.  This would ensure  the battery doesn't get disconnected.  You could fit the negative lead to the battery in the same way  , but its better to find somewhere to connect it directly to the car body.

I've not done the job on my own car  but I would have thought it would be easy enough to run the lead to somewhere convenient in  the car interior so you can connect the charger without having to lift the bonnet every time..  Either using the connector plugs supplied by CTEK , or  CTEK's own (rather expensive) plug lead accessory . For other brands of charger   you could use standard SAE connector plugs like these

That connector is what I crimped on to the Lidl cables since they came only with clamps. The Maypole already had it as an alternative to the clamps. Both have an in line 5A fuse.
I leave the bonnets down to 1 cm gap while charging so the engine doesn't get dusty   
I suppose if it was easy to get a longer cable under the dash you would have to leave a window gap to get a mains lead into the cabin.

Thanks gentlemen. Some neat work and I like LV’s connection to battery clamps using another nut.

[Lord Voltermore]

My idea of having the connector plug inside the car to avoid opening the bonnet was  not one of my best ! Please ignore my senior moment.

  I had thought maybe of leading the charging cable through the open door then shutting the door on it.   But on further thought this would risk damaging the cable, which might short out , or damage  the rubber door seal, bodywork etc.   

[Kremmen]

Once connected, if you just slowly lower the bonnet/hood and don't push it shut you will be OK

Got found to installing a CTEK charger connector to my battery this weekend.
