This cell has “40A max” on the wrap, which is an absurd overrating. Its appearance is identical to the Samsung 25R5 but this Brillipower doesn’t perform as well. It appears to be a lower grade 25R5.
It has an exaggerated capacity rating of 2600mAh on the wrap. This is only a 2500mAh cell.
The wrap has “IMR18650” on it but this cell does not use the chemistry associated with the IMR model number prefix. It uses the chemistry sometimes indicated by the INR prefix.
I am rating this Brillipower cell at 20A and 2500mAh. With all the other cells that are available to us this one is a terrible choice and earns a Do Not Buy recommendation from me.
The two cells that were tested were purchased for that purpose by me.
