Hi everyone and happy new year to all those that I would not have wanted yet, I would need your help to get information (no matter which one) on a 18650 Samsung cell that I did not know the existence until today, its model name: INR18650-15J.
For the little story, I ordered a Black & Decker BL1518ST batterypack (ST for SmartTech, their new management technology and information on their Batterypacks via Bluetooth), so it’s a 18V and 1.5Ah lithium-ion batterypack(thus equipped with 5 cells of this type) and being intended to portable high power tools. So out of curiosity I dismounted this batterypack, and to my surprise I fell face to face on 18650 green cells (same color as the Samsung 25R5), and I thought I was really something new. And I read “INR18650-15J SAMSUNG SDI 1G54”.
So I’m doing some investigation about this cell and I ended up stumbling on the webpage of a wholesaler proposing this cell model, see the link to this web page: “https://www.google.com/search?q=INR18650-15J&ei=PFkvXNOlKYLeaqO9uvgE&start=10&sa=N&ved=0ahUKEwjTs5jbl9TfAhUCrxoKHaOeDk8Q8tMDCJUB&biw=2327&bih=1216”
By reading the specifications of the cell indicated on this web page I could see that they speak of a 1500mAh 18650 cell and 30 amps of continuous discharges, but all the same I remain skeptical about these supposed specifications, because not finding any documents “datasheet” concerning this cell, the wholesaler could very well totally exaggerate the performance of this cell, it is for that that I ask you all if you would have information (documents, curves of discharges, etc …) concrete to propose to me? Regards and respectfully , HydrAxx
Here a few days, I will carry out some additional tests by keeping you informed on the results given by these cells: internal resistances, test of capacities, temperarures, etc …
P.S: I’m posting photos of the cells concerned of my batterypack, so that you can see for yourself!
