This may seem kinda basic, but according to google analytics I received a fair number of hits to my website of people who are looking for Arctic batteries and battery upgrades. This orginally appeared on my website at and has been slightly modified for posting here
First thing you need to do is get yourself a protected 18650 cell. These can be bought cheaply online. Around $3.50 apiece. I’ve ordered cells from dealextreme.com before.
Once you have the battery the next thing to be done is to carefully make a single cut down the heat-shrink. (We are going to use this over later)
The next thing to be done is remove the hear-shrink. Now from this point on you have to procede safely. If the band that come from the circuit board to the positive end of the battery touches the case of the battery cell the lithium battery could short circuit and possibly explode.
Okay so now we have a dangerous battery just sitting on the table in front of you. We want to make the battery as safe as we can as quick as we can.
Okay so what we are going to do is remove the band that runs up the battery. We are going to remove it from the positive end of the cell. The band is attached to the cell by 2 spot welds. All you need to do to remove it is give it a gentle pull and twist with a small pair of needle nose pliers. Be careful not to let the pliers create a short between the positive end of the battery and the body of the cell.
A simple tug and twist will remove the band off of the bottom of the shell.
You can use a file to clean off any burs that occurred from the spot welds.
Alright so you know that heat-shrink I told you to save. Your going to cut off around a 1/8″ off of the bottom of it.
Now wrap the cell with the heat-shrink and cover any metal that exposed on the sides with cello-tape.
TADA you have a cell that fits your Arctic.

One big issue of the S3 Arctic is the lack of battery options for it. The S3 uses an “unprotected 18650″ li-ion battery. Finding unprotected cells are more difficult than protected ones, this turtorial will show you how to convert a protected 18650 battery into a battery that will work with the arctic s3. This. tutorial is fairly straight foreword and can be done in a few minutes. If this isn’t done properly you could get injured or ruin the battery, you do this modification at your own risk.First thing you need to do is get yourself a protected 18650 cell.
