Just got one of these and it's bulging in the middle. Is this normal or is it usually flat like batteries usually are?

I got two of them and neither one is bulging in the middle. They were both flat like batteries usually are.

Thw orginal one that.came in my phone was and still is flat. If it is bulging in center, in my opinion, that indicates damage.

It is usually flat like other batteries but you may see some sort of bulging at the top of the battery (near samsung logo). Bulging in the middle is not normal.

If its for a S4, it should be flat. The battery that was sent to me was half the size so I threw it out. I did not really look at it once I saw it wasn't going to work.

Should be flat.....That's weird may be defective or exposed to too much heat.

Hmm.Nope that doesn't sound right. I bought mine months ago but it was flat like a normal battery should be. I would contact the seller and let them know?

I don't think that is normal, because my charger does not do it. So far I have not had any problems with the charger or the batteries. You should call the company and ask them about it. I am extremely satisfied with this product.

Probably an hour for a full charge. I finally had to replace my battery because it would not hold a charge. Pull yours out and see if it is bulged in the middle. If so it is bad.

Yes, I have it in mine. Had a little bulge in the beginning and now its either gone down or I just dont notice it anymore.

Silly to check but make sure the batteries are inserted properly (corosponding +,-) second the cathode and anode may not produce enough compression and may need to be bent towards center 1-2 mm.

Battery probably bad. If you let NiMH get absolutely flat (discharged) they CAN reverse polarity.

I agree. Send it back. Mine has been perfect. Changed the battery once and it works great.

Check to make sure the battery contacts aren't bent. Double check to make sure the new battery is actually good and that it doesn't have one of those clear insulating stickers on it. Maybe try a different new battery if you don't have a tester. We keep a spare pendent, just in case. They're quite inexpensive.

I have also noticed that one of mine also when fully charged and used little drains very quickly. This is not normal for a good lithium.I have only used one of the two but makes me worry.

No. I thought the same thing, but actually the end comes off like most other battery inserts. They had sent me an email telling me that, but I ignored it as spam haha

Since your battery size is listed, could it be that you are expecting a tighter fit or that the battery was upside down? If neither is the case, I would contact STK, as they are very accommodating and helpful

here is the image search results of battery holders. http://www.bing.com/images/search?q=AA+Battery+Holder&qs;=n&form;=QBIR&pq;=aa+battery+holder&sc;=8-18&sp;=-1&sk;= . notice that the positive side always goes against the bump. that is the right way.

I've noticed that, after some use, the light becomes harder to turn on and will occasionally stop. If you pop it open like you're changing the batteries, you can adjust the metal case surrounding the battery. Sometimes repeated pressing will warp the thin metal. If you widen the space between the metal top and bottom (make more room for the batteries), it allows more room for the button to press. If the metal top and bottom are too close together, it becomes impossible to squeeze them together.

My charger makes a similar clicking sound in the float mode, which appears to be its normal cycling process. It's holding my batteries at 13.3 volts which is near ideal and is apparently not over-charging.

Funny you should ask! I just got through changing the battery myself! You have to squeeze the two oval buttons on the side very hard and make sure the front and back face the right way. If you're very careful you should get one side button on slightly ahead of the other. Don't force it or it will break and you'll have to ducktape it back on!

My experience is that the battery gets loose. I have 2 batteries in the one I'm using now so that it will be tight. This works for me. I have tried other brands but none are worth owning. Good luck.

I purchased mine 6 weeks ago and am now having the same issue. I am wondering if yours and mine are from a bad lot. I have emailed the seller directly (per Amazon's instructions for defective batteries) and am waiting to receive an answer. I will most likely email the address on the box it came in if I don't hear back from the seller very soon.
