I have a nexus 4 - will this charger charge to 100%, turn off, then turn on again if battery discharges? i.e. keep battery about 100%?

hi, you know im not 100% sure.. but I place my LG-G2 (w/ cover) on the charger every night before bed and its 100% charged every morning..so I would assume it does as you ask or while on charger the charger consistently gives it a charge so battery doesn't have a chance to discharge.. its a great device, wish I would have had one sooner, prefer for the night stand.. don't have to worry about wires or trying to find the wire behind the bed to plug it in.. buy it! have a good one

That's a good question. It stays on all the time, and seems to be indicative of whether the charger itself is getting power, not whether your device is fully charged. I have not been able to decipher whether it actually stops sending power to your device when the device is charged, so for that reason, would not buy it if that's the most important feature to you. However, it could work great for a night light for travel!

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 assume that you mean "does it stop charging once the battery is fully powered?" My understanding is that this one does that, and seems to keep the battery charged if it stays inserted. The small chargers that came with my tools did not do that.

My problem was that it would just quit charging(indicator light would clear)prior to actually charging fully. It was advertised as a "Super Fast" charger, however while Li-Ion can take a very high charge rate, NiH can not and will overheat quickly, sometimes with dangerous results, and even if they don't pop they can/are damaged by high charging. IMHO the charger is s PoS which never worked for me

i believe the charger turns off automaticly after the battery is charged at least some do tho some chargers tell you that you are useing unnecesary electricity by leaving it on but i would suggest removeing the battery once it is charged.

Basically an old wive's tale at this point. Modern chargers mostly detect when a battery is full and stop charging (or drop back to just trickle charging). I wouldn't worry about it unless a manual for a device specifically says to disconnect the charger after a full charge. There's so much mythology and repeated nonsense out there about batteries, chargers, and how they work!

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.

when i initially got the item i charged the battery for four hours anything after that and the battery gets pretty hot, now when i charge the battery , since i only have one smart charger i charge one battery with the smart charger and charge another battwery with the stock charger, when the smart charging is complete i disconnect the stock charger, works for me. it pretty much lasts for a while, ev3n after i put it away after use, it's still charged when i use it again a few days later.

Depends. If the device is powered off it will almost always charge (slowly). If it's turned on it might either charge *very* slowly, or not at all, or even still lose charge if you're actually using the device. (You'll see the latter with high-end phones or tablets if you are running a 3D-rendered game -- the device will be using more power than any USB charger can safely deliver, so the battery will slowly drain even if it's plugged in. With a crappy charger this can happen even if the device isn't doing much.)

Just a couple of guesses. I have two chargers - one never worked - thought it was the battery, but the batteries work when charged on the charger that works. Somewhere in their info I read that the batteries shouldn't be drained down to zero - has that happened?

Yes. When charging my nexus 4 it shows "AC" charging from multiple sources.

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.

This should be able to charge any cell phone that uses a single port connection. For example the S5 has a dual port connection, however, this can still be used in the one port. It should work fine with the Nexus 4. I use pretty much any cord if one is around to charge my cell phones. Sometimes, if you have a bigger battery it might take longer than the original charger that came with the phone.

This unit is for charging electronics, so if your nexus 4 charges with a cord that can plug into a USB port, this will work.

Hello Stefanie, the battery pack charger is always ready to go once its fully charged (first time, only) and is intentionally made without an on/off button. The "touch switch" on the front of the charger will tell you how much "juice" or charge remains in the battery pack by the lights that show up when you touch the little hand (or touch switch): 4 lights = 100% fully charged, 3 lights = 75%, 2 lights = 50% and 1 light = 25% and its time to make a plan to recharge the battery pack. Thanks for asking, if there is anything else, I'm here, Sherlock hones

Some chargers do this from time to time. I find that I get a better charge on my phone or tablet. In this case this charger is for your tablet. So the reason it does this is because it's not programmed to charge while your tablet is on. At least this is what I was told about my charger. So maybe get a new one or just use it and turn it off to charge.
