Same LGABC21865 cell but K117D276A6 only test at 1800mA. Four more on the charger so conclusive results are half a day out. Best of six was 2000mA. 1800 to 1880 on the rest. Full discharge then charge/test on Opus C3400

I think there may be 2 entries for the same cell, just made in different factories.

https://secondlifestorage.com/t-LG-LGDBC21865-Cell-Specifications

From memory I read elsewhere on this site, that the "DB" and "AB" part of the name indicates where the cell is made, and the "C2" part is the model number.

Also on both listings is the same "Data References" link
http://www.batteryspace.com/prod-specs/5702_5.pdf

The "Standard Charging" current is listed as being different on each listing.
From the linked PDF, I think (1350mA) is correct.

I want to buy this battery. How
This battery, LGABC21865, was very common in HP laptop batteries from 2010 to 2014 I have purchased several "bulk" hp batteries on ebay to reclaim these cells. Many forums and YouTube videos will tell you to test the battery after you reclaim them and if they test under voltage they are bad, however, I have found this to be false. These batteries have not been depleted from over use but from setting to long without a charge. Using a proper charger then using a proper capacity tester you will notice reduced max capacity but will function properly. I use them often in 12v and 24v builds. I personally use miboxer model C8 to reset and charge them, then opus model BT-C3400 to test them. As you can see in the pics the cells were restored to 2500mah not the original 2800mah and all of the cells measured 1v or less before restoration.
I use the miboxer becuase it will trickle charge with constant current (cc) until the volts are back up then it will slow down and maintain a constant voltage (cv) until the battery is full and will not overcharge the cells, also most chargers will reject the cells becuase they are under voltage.
After charging, set them aside and check voltage 2hrs later, I set aside any cells that fall under 4.10v. Since the charging process does cuase heat in the cells, the voltage will drop a bit once cooled. I then check the dropped cells once more 2hrs+ later, if they drop at all I discard them.

I hope this information and pictures help, and as always, be safe when working with unknown cells and inspect all cells for damage prior to charging. Replace damaged wraps before charging and have fun!
