I bought a CTEK Battery charger MXS 5.0 and tested it between yesterday afternoon and today. And I used my Chinese battery Monitoring II spy.
I connected the CTEK to the “under hood” positive pole and earth connector. I have to admit my picture could have been better:
I brought the current extension under the car, so that I could close the hood (bonnet) and lock my car. It rained this night, and my car is in the garden.
I started the CTEK battery charger at 14h45 yesterday, at a moment that my battery was indicating 60% and about 12.4 Volt.
The phases of the battery charger are as follows (RECOND not applicable for normal lead acid batteries).
First graph is yesterday and in fact it jumped almost immediately to phase 3 of the charging process (14:45).
The three “peak down spikes” are moments that I had to open the doors of my car, and are therefore not related tot he charger.
The second graph is this night, morning and afternoon. I disconnected in the “float phase” (13.6 Volt according tot he manual, 13.7 to 13.8 ripple according tot he battery monitor) around 9:00 this morning. Spike down at 9:00 is again opening the doors of the car (had to open the hood).
I guess the spike down at 3:00 in the morning is phase 5, where it checks if the battery can hold 12V: this lasts not more than 3 minutes!
The rest of the graph (after 9:00) is after disconnecting the charger. The voltage drops to 13.1 Volt and stays there.
Nice little device this CTEK MXS 5.0 and easy to use! (Thanks to an advice of @DCPU).
Tomorrow my car goes to the dealer for some “repairs”. Please wish me good luck! I will also ask some questions to my dealer, I need also luck for this: answering my questions isn't their favourite activity.
