Does charging stop when battery if 100% charged?

No it doesn't. But when your phone is plugged in it doesn't stop charging till it's unplugged.

Yes. It works just like your wired charger (except it has no wires) with a few key differences: 1. Your phone limits the current received in this way (the limit is device manufacturer specific - my SG S4 will only take 700mA via its wireless charge port) 2. The QI wireless charging standard limits the max current to 1000mA. 3. The phone will charge fully (within the limits above), turning "off" the wireless charging port when done. The thing is, then the phone almost immediately starts to deplete the battery, and the charging resumes (speaking ONLY from experience with my device). The final net effect is your phone enters a "floating battery" state: the charger is powering your device, while your battery sits idle at 100%. I have left my S4 on the charging pad overnight many times, the same way i have left it in the wired charger overnight many times... same result either way - phone works just like it did previously, just the way i know it to work.

When battery is 100% Charged, charged on the screen shows, the charger no stop.

I noticed mine will do that if the battery is fully charged. Is it possible that could be the case?

It does not need to be in the "off" position to charge. I don't recall if there is any "charging complete" indicator.

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.

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 do not know if there is a mechanism to prevent over charging. For your second question: there is an LED with various patterns of blinking to indicate charge level. "Slow red blinking: 0-50%. Slow green blinking: 50-80%. Fast green blinking: 80-99%. Solid green: fully charged."

When all three lights cease completely the battery is charged. I usually just feel the top of the charger if it's cool then it's done.

No. Battery stops when charge is depleted. It has made such a difference .... keeps inside temps moderate. It has lowered our attic temperatures. Quiet and we are pleased.

If the charge is full it will stop charging automatically, but the lights will be green

Yes it completely shuts off when battery is charged, and restarts if battery discharges below a set point.

Yes the charger shuts off when the battery is fully charged but will come back on when the charge goes down.

Yes, this "stops the charging" by blocking the incoming power on the "solar panel" connection from getting thru to the "battery" connection once 14V is detected on the battery terminals. Once that has happened, the green light comes on to tell you "the battery is full and charging has been stopped" and the green light stays on until the battery voltage drops to 13V. Once the battery voltage has dropped to 13V, the charging is enabled again and the green light goes out (but the yellow light will be on showing that "charging" is happening again). Depending on how well charged the battery is, how big it is, and how powerful your charge source is, that full cycle (of charging, reaching the 14V where charging stops, and the battery dropping to 13V from it no longer being charged) can happen in just a few seconds or can take 5 minutes, so seeing the green light go out and come back on often is normal. The only time a red light will come on is if you have a "load" connected to the "load" wires and have something running so long that it drains the battery so 11V is detected, it then shuts off your "load" so you don't overly drain the battery.

Yes it is. It will send a charging current to your battery in three stages. As the battery starts to approach full charge it will cut back the charging current to keep from over charging the battery. When the battery reaches full charge it will go into a maintain stage which will keep the battery charged.

If your batteries are in good shape the charger will shut off when fully charged.

This is a normal behavior with battery extenders and overnight phone connections.. Modern cell phones and lithium batteries don't continuously charge, they stop when they get to 100% and then start again at 97% or so.This means once your phone is fully charged it stops drawing power from the charger, and the charger shuts off. So 30 minutes later when your phone battery is low enough to try to charge again the external power isn't there.

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

No, it just stays red to indicate the charger is connected and working properly. I just charged mine for 24 hours initially and overnight since then to recharge. They recommend you never let the battery fully discharge.
