Charge 12v battery using 12v charger?

[Kithmo]

Looks about the same as ours and does the same functions from the sounds of it.
I've only used mine on the ZS once about this time last year and it did the same, Green light after around 1-2 hours.
It used to take several hours on the Prius, smaller battery, probably took more punishment.

I've used the 5A CTEK on my RS for years.
It has hardwired connections to the battery so it's plug and play for day to day use..

Yeah - I have the same eyelet quick connect loom, permanently connected onto my battery.
Not over keen on the crocodile style clamps, they can spring off.
I also purchased the optional longer extension cable, that fits between the battery fly cable and the charger.
It allows me to have the charger plugged in inside of the garage ( away from any bad weather) while the extension lead then passes under the door, then under the car and up to the battery area.

I have a smart CTEK 12 volt battery charger, that I have used to “Top Up” the battery on our ZS EV a couple of times.
It comes with an accessory fly lead that has two eyelet terminals, that can be permanently attached to the 12 volt.
The red positive terminal is attached directly to the + positive terminal of the battery, while the black eyelet - negative terminal attaches directly to a ground ( earth ) point on the chassis of the car.
At the other end of this short fly lead, there is a weather proof connector, that mates up with the leads on the CTEK smart charger.
Just very convenient, safe and quick to connect and use.
Much better and safer than using them crocodile clamps that tend to jump of the terminals !.
The charger does come with the crocodile clicks if you need them.
As said above, I have used this charger about 3 - 4 times now and not disconnected the battery terminals from the battery.
If I was using a high capacity garage charging unit, then I would consider disconnecting the - negative terminal first.
But a lot of the small smart / conditioning chargers are only providing a very low trickle charge over a longer period of time.
If you had a completely flat 12 volt battery and called out the rescue services, my guess would be that they would attach a commercial high powered jump pack directly to the terminals of the 12 volt battery, without disconnecting them of course.
So, using a low powered trickle charger with the battery terminals still connected is not a problem really.
I would purchase a trickle charger if I was you !.

Thanks for the info. I have the same attachments.
