    I have that with the dumb charger my dad uses. Only, I use a smart plug.

    I want one of those. Something to look forward to once we upgrade our Jurassic DSL connection.

    There are inherent risks when charging FLA batteries that has a lot to do with hydrogen gasses and arcing, which I already covered a few posts back. But as far as other electrical/electronic devices, the order in which a device is connected and powered depends on the specific equipment.

    As per your example, laptops can be powered up before (ie. on-battery) or after the AC power is applied... it won't matter.
    Good info.

    Though dahil may pagka OC ako, it has always been my practice to do what I think is the safer way, may it be a laptop, TV, cellphone, or a blender.

    I was about to ask what is a smart plug but tried Google first. It says that you can control it through WiFi.

    I keep learning from you! One of the reasons why I keep coming back in this forum. Good thing this thread is in my subscribed topics.

    Yes, you can control it over WiFi through an app or Alexa/Google Home.... from anywhere in the world.

    Beyond that, you can also set schedules to turn on and off at specific hours of the day or days of the week. It sort of makes a dumb charger a little smarter.

    I had the opportunity to observe more how CTEK works. Once the battery is fully charged, it will stay at a minimum voltage of 12.63 V for a few days.



    After a few days, and I don't know how many days, CTEK will "play" charging the battery between 12.63 to 13.18 V. I forgot to measure the time interval.





    Once I left the car for about two months and when I started it, it was the first time for me to hear it cranking forever. It was when I didn't use CTEK. It must be noted that I am using a "cheat version" of battery. This is an ordinary battery by Motolite, given free by my friend. I never experienced this with the stock battery, not until it died.

    Right after turning on CTEK, voltage will climb slowly, for about a minute, up to 14.05 V.



    This is a little lower than the charge coming from the alternator at 14.46 V.



    I do not know what is my stock battery, if it's an EFB or AGM. All I know is the brand, Yuasa. It is unfortunate that I wasn't able to observe CTEK on my stock battery, the way I was able to observe it now.

    The engine stopped running, some of the console settings were lost like fuel monitor, this happened during battery replacement.
