12v battery replacement

I've never had any issues by CTEK charging via the 2 terminals direct

I did look into that when connecting, but information is not consistent or maybe well informed accurate. After 5 Civics, the E and the Jazz never had a problem with either an old transformer charger (in emergency) or now 2 different micro controlled pulse chargers. I top up often due to low milage, if you are charging while off the main processor should measure the voltage when you switch on and act accordingly.

I have copied Kremmen, using a spare Opitmate lead i had. Not had to use it yet but I think it makes sense.

As a postscript to my original post, I put the original Panasonic 12v battery on a 48hr trickle charge as it was on the bench. Although it initially showed a healthy 13.24v after that charge I decided to load test it, with just a small 25w inspection light and was amazed how quickly it began to discharge the battery confirming it is beyond saving.

There is a pertinent observation at https://clubjazz.org/forum/index.php?topic=16239.0 about the way the vehicle charges the 12V battery.

I remember, back in the 50's, my dad had an Austin A35 van and he used to have a white/red light that clipped onto the top of the driver's window glass

It was powered from the car battery and lasted all night and the van still started OK in the morning

I wonder what battery they had

I dont think the batteries always coped. The A35 still had a starting handle.

Now that’s really taking us back

..... and it didn't have flashing indicators but the semaphore arms

Now we have seat belts, I used to sit in the back on one of the wheel arches

I remember my Dad's two tone Ford Consul (height of extravagance) and that light when parked on the road, which flattened the battery overnight the first time it was used.

I seem to recall that way back then, depending on where you parked it was law to have the offside lit in the dark ?

Can't remember which car but I had one that when parked with the ignition key out you set the right or left hand indicator and that lit the front and rear parking lights for the side selected

Still applies. Highway Code Rule 249.

Hi, is the negative connection connected to the negative post? Does this affect the efb smart  battery management gizmo? I was under the impression this could cause problems with smart charge gizmo?

I was told the same thing by my Honda dealer and hence have screwed the negative eyelet of my CTEK to the looong mounting bracket screw (which seems to be grounded enough for my 3,8 A CTEK charger).

if the battery charger is connected directly to the battery terminals the Battery Management System is by-passed and the cat may not recognised that the battery has been charged.  The instructions with a CTEK charger clearly state that the negative cable should be attached to an earth point away from the battery.
