It would eventually charge it, I wouldn't leave it on any battery indefinitely though as it has no automatic mechanism that will prevent overcharge.

Yes. The charger is a smart charger. When the battery is fully charged, it goes into a hibernation mode and will maintain the battery, without overcharging it.

The overcharge protection is part of the device being charged, not the charger/power source. It won't keep your auto repair shop or insurance agent from overcharging you!

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry. I cannot answer that question.

No it has a built-in overload circuit to prevent damage. I've done it and nothing happened.

It does have over voltage protection. But since power in the US, 120v is just in name only so you will get naturally get a little over or under.

Well it depends on what charger you have. This item is just the batteries. But as far as I know, and this is what mine does, most of them will stop to prevent over charging. But you would have to look at the charger when you buy it.

I have for the last two years. I only recharge the battery 2 or 3 times a year. I don't overcharge it. so far so good.

Yes. I would recommend you use a smart charger, like a Battery-Tender, that senses when the battery is getting charged and switches to a trickle charge, to avoid overcharging.

No, but the battery lasts a long time. Also, there is a key override feature.

I saw nothing in the literature to indicate a problem with overcharging. I have not had the unit long so not much personal experience. So far it has been great.

I usually keep it charged when using it, so I'm not sure if it does or not.

You cannot overcharge the battery so don't worry about it. Also no harm done if you undercharge. I have had mine for years, and to be honest do not charge it regularly, and have not had any problems. These are really just guidelines.

Yes. It will shut down the 4 led status lights even if left in charge. So no overcharge or heating issue. Unplugged it will last a very long time I tested a week in stand by and still all 4 LEDs on. Good product . very happy with it

Yes...according to a Clarasonic representative it is similar to a toothbrush charger. The unit can remain in the charger and plugged in all the time. You can not overcharge it.
