Brand new Batteries do not want to charge

[Bakseated1]

So I ordered two Ultrafire Flat-Top Protected 14650 Battery, 1300 mAh to run in my wife and I's E-Powers. I take them out of the box throw them onto our two plain jane single battery chargers that came with our E-powers and they both show green.

We both put them in and start vaping. About an hour later both of the batteries die. I am thinking to myself, wow these new batteries dont hold much of a charge thats disappointing. I take them over to the chargers and one of them just shows green on both chargers. The other one shows green on one charger and on the other if you fiddle with it to where it feels like its about to pop out it will show red and start to charge. We have had about 5 other batteries and only one sometimes had to be fiddled with to get it to charge.

Whats up with that? I would hate to buy a new charger and have that not be the problem but I also dont want to send these batteries back and have the replacements show up and do the same thing.

Any ideas?

Do you have a DMM so you can check the voltage when they come off the charger? They should be around 4.2 volts when Fully Charged.

Sounds like the Charger is doing what it should or making a poor contact with the battery.

I have Trustfire TR-001 charger and only can charge 1 flat top battery on the left side.

The cause of the problem - the "+" contact isn't protruded as well on the right side as the one on the left.

The thing that struck me as odd on this question is that every e-power I have encountered uses button top batteries. Not flat top.

The charger seems to be for button tops from the connection issues too. (I'm not an Ultrafire/Trustfire fan either and would be inclined to have the OP do some research on batteries, but I don't have my links on this access device.)
