I'm aware, I put it in there twice because I wanted it under IMR (since it does such high currents) and under LiFePo4. I understand this is not technically correct since it is not LiMn cell, so maybe I should remove it from the IMR section?
True, but I feel it should be there. I guess I'm sorting by function not strictly chemistry. I'll leave the LiFePo4 batteries in for the smaller batteries at least because some lights can take a 3.3v battery but not a 4.2 volt battery. 16650, 18500, and 10440 will be added later today when I get a chance. 32650, 26650, and 32600 will be added at some point in my 3rd comment which is for bigger cells.
The graph actually came from the datasheet (which I did link to already ), which is here.
begging for a spreadsheet…. i know some do not have excel but open office is free and i think it would solve a lot of organizational problems. my apology if there is a spreadsheet in here somewhere i just could not wade thru it all
32650 and 26500 will be added tomorrow. If anyone has any further suggestions post here or PM me. Also, if someone can clarify what is wanted in a spreadsheet that would be appreciated.
Choosing batteries: Scaru, could you please point out to beginner purchasers that that there are three main types of contact points on the positive end. Flat, button and nipple. The “button” term can be misleading, because its generally used to describe both button and nipple. Some flashlights with reverse polarity protection such as Eagletac, require nipple tops. A nipple top has a smaller diameter button than a true button top and is usually raised up a little more.
It is good to double check when purchasing, because photos of button tops sometimes make them appear to be smaller in diameter and result in awaiting a new battery only to find it will not work without the aid of a magnet.
Ok, done with the larger cell section unless anyone has any requests. I added this info about button tops and magnets.
"There are 3 main types of positive contacts used on the batteries. First, and most common is flat top; these are a simple metal contact no higher than the surrounding label. This is the way batteries generally come from the manufacturer. (Does not apply to NCR18650 series) Then there is raised top, or button top, this has the same contact size as the previous one, but the whole surface is raised. This is needed in lights where the batteries are stacked to ensure contact. Then there is nipple top, this has a small raised top; much smaller. Some lights that have mechanical reverse-polarity protection require nipple tops.
People often use small round magnets to create a a nipple top from a flat top. To do this one simply places a magnet on the top of the battery, this does come with a risk. The magnet can easily slide out of space and short out the battery, it is for this reason people often place a dab of superglue under the magnet. An example of one of these magnets is this. "
And I'll ask one last time, what would you guys like in a spreadsheet?
