can it charge bateries indefinitely

not sure but I would think not....I have a charger similar to it for my drill and it can only stay charging for 8 hours.

No the batteries do discharge over time. The length seems to depend mostly on the age and use of the battery. I try to recharge a battery fully after I run it down completely and since I have 3 batteries I always have one to run on while I wait for another to recharge. I will be going to the lithium units now that the prices have gone down when these fail. I bought a spare drill with a charger,and battery and stud finder on Amazon from the Amazon Warehouse for $42.20 so I'm good for a long time I hope. I have had this drill for 3 years now and it is great for home use, but not for commercial day to construction. No the batteries do discharge over time.

No, With any rechargeable you can't. It's not a dust Buster charger of sort! It stays charged a long time. I grabbed it after a couple of months, Still well charged. But I would advice to use & grain it once in a while, & recharge!

Its absolutely perfect for this. I use mine for these things exactly. I dont know how many charges you will get, but it will be many as long as you keep the unit charged.

You can charge that if you can get it to work. I was not able to charge a single battery with mine. It keeps shutting off like it is overloading or something. Total junk. Buy something better. You get wht you pay for.

No-It appears to work by an automatic switch. When plugged in battiers off-[unless you have rechargeable batteries-then they are charging]-other wise the regular batteries are bypassed when it is plugged in. Michael Barnes

Yes, It can be Used while it is being charged. And its working perfectly as well.

This is a smart charger and as such it senses when to charge the battery and when not to with its built in circuitry. So yes, you could leave it hooked up to the battery indefinitely with no damage. Many people do this in the off season when a battery is sitting and not being used. Otherwise, you could be purchasing a new battery if it sits to long and discharges to the point that it can't recharge.

Yes. While they seem to be somewhat tolerate to overcharging you can ruin them. I've left them for 12hr and had no problem. But when I forgot about one and left it for a day. It was ruined. It just wouldn't hold a long term charge anymore. I had used it quite a bit so it may it was just its time to die but all the others I've had have lasted a very long time.

Yes, u gotta charge every 24 hrs at least. Its one of the few pains, esp. when traveling.

Yes! You can. It charges pretty quick too, i find the life per charge to be pretty decent.

I have not tried that because the batt. Lasts so long, but you should be able too.

you can only use it till it loose its charge, then you have to charge it someway. Cleaning station charges it too.

Probably but only over a long period of time and it will only maintain a charge, not charge the batteries up from dead or low.

The charge does decay. If you charge it over night it could get you out of a pinch during the day.

If there is, it's by no means accessible to the average consumer. The clear answer is no. You can charge this through its micro usb port and then have it ready to power an electronic off the (full-size) usb slot when needed on the go. If it dies, you get a new one. If that's a concern then get a better, more expensive one.

Yes you can. The charger is designed to recognize a full charge and then will trickle charge so that the batteries stay charged and ready but not overcharged. I am doing the same on mine

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.
