Can I just keep it plugged in with the batteries until needed, or do I need to unplug it once the batteries are fully charged?

I don't leave mine plugged in and I found this on the Apple forum.."Thanks to an intelligent power management system, the Apple Battery Charger uses less power once your batteries are fully charged, making it one of the most energy-efficient rechargeable battery solutions ever." However, for maximum life, you should not leave the batteries plugged in all the time." It doesn't take long for the batteries to charge fully and if you have an extra set charge them as soon as the "mouse batteries low" shows up on your screen and you should have no lag time.

Yes, it can stay plugged in, which maintains a trickle charge, but if you're expecting to need an absolute full charge to be available when the batteries are finally put into use it's really unnecessary I think. NiMH batteries hold their charge pretty well when stored after being charged. I can get a full month of use out of my Apple Trackpad, even though the Apple brand NiMH batteries were charged and then stored for week or two.

I am not sure it is wise to keep batteries on charge all the time. I always disconnect the charger after a full charge.

unplug when charged. keep the 2 extra charged for next time the mouse or keyboard needs it.

It has been my experience that it is best to disconnect the battery once it is fully charged. I don't think it will be unsafe, just not good for the batteries.

No it does not have to stay plugged in until one lets the air out.You plug it in only to turn on the built in electric pump which fills the air bed with air and it stops automatically when filled and then you unplug it and put the electric cord in the slot at the end of the bed.

I have 2 batteries for my trimmer. I charge them both up and unplug them from the charger. You do not need to leave it plugged in. When the green light goes out they are ready to use.

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

The person I purchased this unit for, leaves it plugs in at all time. She unplug unit for several day while on vacation, and the battery died. So I suggest you leave unit plug in at all time to preserve the battery life.

All you have to do is plug into the wall and put your batteries in the container. The side bar will let you know once the batteries are fully charged.

Does not have to be plugged in all the time. Just after using it and every 30 days. I don't know how much current it uses but you can keep it plugged in and it'll stop charging it once it's fully charged

I really don't know. I don't plug the unit in, unless I have a handful of batteries to recharge. Then the light goes on, and I figure the batteries are all recharged when the light goes off. (Trial and error?)

You can leave it plugged in using a usb cable with a plug in adapter at the wall, similar to a lot of devices now that charge via usb cable. Just leave it plugged in and it will operate off electricity and keep the battery charged. Be aware that on mine the water in one speaker quit "dancing". Not sure what this was related to but probably not a power issue but defective.

You can keep it plugged in to the wall. Not sure if batteries can be replaced.

To answer your question, yes, it can run solely on battery power for at least a handful of hours if it's completely charged prior to use. The company recommends a full 24-hour charge before using it for a prolonged period of time, whether it's plugged in or not. If you're just using it for an hour or two, it's fine to keep unplugged, but any longer than that, and I'd say plug it in.

It's up to you. It does not hurt the charger to leave it plugged in. But if you want to unplug it, that's OK too. I leave mine plugged in for convenience.

No, you don't have to unplug it and as long as no devices are plugged in the battery will not drain. Be sure you have the cover closed to protect it from accidental shorts due to water, debris, etc.

I believe either is OK. I usually leave it plugged in during frequent use. For storage, I unplug then charge prior to use.

You keep it plugged in and charging while not in use. When you are ready to use, simply unplug and it is ready to go. Very simple. Great machine.

yes you leave it plugged in when not using. I have had 3 of them now thy are great for jumping vehicles. recharges fairly fast.
