what would happen if you charged these at 1.8 or 2 amps to fast charge them

I'm not a battery expert, but you should really stick to the charging voltage and initial current they show on the battery. Overcurrent will certainly warm it up and it may leak or explode on you, or just shorten it's life.

The amperage will decline to a low value-perhaps 1 or 2 Amps. Probably the best way to know the state of charge of your batteries is the old-fashioned way. Check specific gravity. Should be 1.260 or higher.

It can charge 2 at once as others have stated, however the faster charge rate of the 2.1 amp outlet will not immediately harm your battery it can cause permanent damage to the battery. Charging lithium ion or IMR batteries too fast will deteriorate the life of the battery. The smallest battery that can be charged at 2.1 amps is a 4200 mah battery, which is not in an iPhone or any other phone to date. Batteries that size are in a lot of tablets. The iPhone's battery is somewhere in the neighborhood of 2000 - 2500 mah. Other phones with removable batteries you can see their size on the battery.

They run hot around 110 degrees and the battery has to new if the voltage of the battery cant go below 8volts

I have a battery tender to plug into the leads. I have used a regular battery charger on them at 2 amps, they still worked fine. I believe these are for a motorcycle battery. I would not put any more amps through them than what you would use for a motorcycle battery.

Lower amperage will charge your batteries slower. Its the amount of current being put back into your battery.

Yes, I believe that should pose no problem. The resistance of a longer wire would just slow down the charging rate slightly, 1 amp is a good charging rate. -a rocket scientist

Drew. There are two outputs with different amperages. 1 and 2.1 amps. Look at the picture above. If your phone charger is lower than 1.75 amps, I would use the 1 amp, just to be safe. If it is above that, it will charge faster on the 2.1 amp output.

No. They're much bigger. They are 3.7 volts compare to AA which is 1.5 volt. Higher mAh too.

No, there are no problems if you charge cell phones on a 2.1Amp port, The rating shown here is a limit. so let's say your phone only allows charging at 0.7 amps, You can put it in any of the 4 ports.But let's say you have a tablet that can take up to 1.8 amps you can put it in the 1 amp port but it will just take longer to charge unless you are using it at the same time where it may not actually charge it would just keep you at the same level while you were using it.

Yes, They will be VERY slow if the battery is discharged, that if what you need a standard charger for, these are just to keep the battery(s) fully charged, which they do very well.

The ones I just charged measured 1.45 V. Some that had been charged about 3 months ago measured just under 1.3 V.

I would not use more than 1 1//2 or 2 amp charge. Most chargers have a switch for this. Jump starting is probably not a good idea, although I have never done it.

Yes, each at up to 5 amps. I have also charged 2s and 3s batteries at the same time, and 2s and nimh

They will be ok. I usually charge mine over night, in the morning they are fully charge. Usually takes couple of hours. Once they are fully charge the charger turns off.

I wouldn't risk it... in my experiences, plugging a charger with stronger wattage into something can cause rather unfortunate problems

Nop! you won't be able to charge them via USB, because the charger it self does not have USB port.
