Does automatically stop charging when the battery is full? Is the overheating a problem? Thanks!

The device being charged is responsible for managing the process. Keeping the phone/tablet on the matte is the same as leaving a wired charger plugged in

I have left my phone on it for hours while the phone was powered on but I have noticed when the phone is off and when it is done charging, the battery pack shuts down automatically so if your phone is off, my guess would be that it shouldn't. Not sure how it would be if the phone is on. Maybe it works the same as it detects the battery is fully charged it may shut off either way as to not overpower the phone.

When charging, the red light only turns off automatically (and the device stops charging) if the switch on the side is off as well. If you only turn off the top button, it'll keep trying to charge. Don't wait for an amber light indicating that the battery is fully charged... I find that to be misleading... at least it has never happened to me.

Yes. Mine is overheating. I just realized and went searching. It charges my ipad great and I love the dual port but it now seems hazardous. I am using a small extension cord since my charging cable is so short...I hope that's not a factor.

I don't have a definitive answer for that, but I have charged mine many times, and it seems to stop when the charge is complete.

I don't recall reading anything that warns you about overcharging. It plugs into the usb port of your computer and charges rather quickly. I have left it plugged in after it was fully charged and it didn't cause any problem that I am aware of.

Re read the manual . There are times you have to put the manual switch on for a few days to charge it to FULL capacity ....especially id you have the second battery attached to it. It always runs down slowly over a coule of months and will not charge if it is not down to @ 75% -80%. Then the manual setting will charge it to full. It may have come to you almost fully charged. Hope that helps. One more thing ..write or call My E they are very helpful w/ any issues.

Mine I've charged twice since about 8 months ago and its always pretty full. I only use in emergency as well but i can always guarantee it will at least be at the % i left it at last. Its probably loses battery about as much as your normal energizer battery not in use.

I charge mine overnight. It doesnt register a full charge. But it seems to work for a full charge.

As I understand from the instructions, you can leave the battery in the charger. It will not overcharge.

Yes, it does stop charging after the battery is fully charged. Older battery generations such as NiMH need to stop receiving power after fully charged, otherwise this will damage the battery. But don't worry, the Tenergy Smart Charger will automatically cut off charge when battery is fully charged. This is why you see the word "smart charger" in the description.

I would say let it drain the battery completely and then try charging it again to full without using it in the meantime. This can happen with new electronics if you use it before the battery is charged all the way the first time. Work in tech and it happens with cell phones too (expensive mistake!)

Never had a problem. Haven't charged mine in four months still has charge. I would try another charger power source to eliminate the charger from consideration.

Yes, it does prevent over-charging. This is accomplished by the charger switching to a type of stand-by mode when the battery is fully charged. Its LED display shows the specific cycle in which the charger is operating. If the battery power drops to a level below full charge, the charger switches to charging mode to top-off the battery again. I am completely sold on this CTEK Charger! Also, it CAN re-charge a supposedly "Dead" battery, if the battery is still capable of accepting a charge. This is achieved through its "de-sulfation" (altho this is not the correct term) process.

You can charge it either way you want. It should operate identically to the original battery (aside from capacity of course). I've only been charging it inside the phone, and I haven't had any overheating problems with it so far.

I see the first answer of this question mentioned that it should be disconnected as soon as it has full charge or almost full charge. I understood the different way. It can be charging for 24/7 continuously without unplug until you are going to use it. So which method is Righr?

Yes the unit will stop charging the battery when the charge cycle is completed.
