Does it continue standalone pulsing/ desulfating on connected battery after I unplug from AC outlet?

Without power (110 ac ) the unit can't function and go through the charging/pulsing/desulfating cycle.

Requires power to function. The charge and pulse work as advertised as long as it has power.

This charger has thermal runaway protection which means it will stop charging when fully charged or if it detects a problem with the battery. No need to unplug, it uses very little power in maintain mode.

I've never unplugged mine for 2 years. It's in the gravel under a building so it shines through the Windows. I scrub it once a month, that's it.

Yes, but not overnight. If left connected for weeks or months it will. That is why it is on the battery tender quick connect plug. You unplug this device and plug in your battery tender to keep the battery fully charged and ready to go while it is in storage. If you don't have a battery tender, you probably don't have the connector that this plugs into, thus you probably shouldn't be getting this.

I don't know what they meant by disconnected. Mine has never been unplugged in over a year. I occasional gently dust it. It doesn't really get very dusty.

We never unplug ours. It automatically shuts off, so I never really saw the need. Never had a problem with it.

No. I love it but wonder if it will drain my battery if I forget to unplug :(

I do not unplug mine whether in use or not. However my power is only on when the car is on.

Yes it does. I unplug mine when I don't use it and it is always back where it was.

No, you have to plug it in the charge it, but then you unplug it when you use it.

No, I think you have to keep it plugged in. I always unplug it when I leave the car. Kind of annoying

Absolutely not. Unit operates when plugged . Once you unplug ,if turned on ,starts operating using the batteries.

Your Battery Tender will turn that on. So I just disconnect one of its power wires when ever I am using my Battery Tender

Yes, I have it plugged in, runs all night, just don't use any timer settings. It hasn't given me any problems at all, still running strong, no stops like 2 different Homedics ones that I had in the past. The white noise isn't quite as loud as the Homedics ones, it's sufficient.

It's not a momentary solution. Power stays on until YOU decide to "unclick" it. It is an awesome lil gadget. I totally recommend it.
