I just bought two of these. It loos like there is a wrapper around the battery preventing charging on the original charger.

If you are referring to the 1.0 charger DO NOT use it with these batteries. If is is a electrical tape type material, it may be you got the wrong battery. There is a similar model without a case, but a wrapping. They work fine on the 2.0 charger but don't have the circuit which stops them from overcharging, and it is dangerous to overcharge them.

Not sure about any wrapper, I purchased two of these also and haven't had any problem charging them with my OEM charger.

My experience is get the least expensive one. They do about the same thing-I have had multiple versions of the original, but all my chargers fit it. Otherwise I would just get a new one.

The charging connection to the battery is inside the cover. The battery charges just fine with a broken USB port.

Hi: I had that same question. So I just bought the battery thinking that would solve the problem. But it didn't. So I ended up buying the charger and that just prolonged things. MY advice, purchase BOTH at the same time and be done with it. JOHN

Make sure you remove the plastic strip between the batteries. They insert them to prevent the batteries from draining, but it will also prevent them from charging if you don't remove them.

you put the negative end on the lower connector on the charger, line it up with the positive connector and push down gently. The battery doesnt lay down totally flat but it will make the connection you need to charge it

The one included did not work. There was no "letting battery run down and needing another kind of charger". It was a simple case of the battery not charging, a common error with this model.

I don't think you can overcharge the battery with the charger. It has an automatic They last a bit longer than the original one. But not much of the difference.

Try and see if there is a plastic tab sticking out of the on/off switch. it keeps the battery from discharging prematurely.

I do not have this problem. However I have been very careful not to leave it on the charger too long. My experience with this type of battery is that if it is frequently left on the chrger longer than 12 hours it looses some of its ability to hold a charge.

One or two things could be the problem ,, first make sure all the plugs are plugged in, then it could be the charger its self or it could be the battery I would lean towards the charger.

There is an issue with the charger I have discovered. It is necessary to unplug the charger unit and plug it in again each time you want to charge. When you don't do this it seems to charge, but really does not. In some fashion unplugging refreshes the unit. I operate two batteries and they charge up fully when I do this. I know, sounds weird, but it works. Can do the whole downstairs on two batteries. Amazing how much more expensive the batteries are now though.

I have the Samsung factory cover and with a bit of a wiggle it slides onto contacts in base of charger. My spare battery fits behind it and charges at the same time.

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.

They fixed it for me. I wasn't going to even deal with it because having the extra batteries was a plus, but after posting a negative review they contacted me and ultimately ended up sending the correct charger without requesting the old one back. I was fairly impressed. Hope that helps.

The silicon is covering the battery. Take out the silicon covering to expose the battery. It is not hard and it can be replaced easily.

Had that problem once, I just spun the battery a little bit while it was still clamped in the charger and it worked fine. Might have been a slightly corroded contact. Never had a problem since.
