These tests below only note my personal ESTIMATED ratings for the batteries I tested at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of property damage, personal injury, or even death. They are not supposed to be used outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Testing batteries at their limits is dangerous and should never be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Test Results
This cell is a decent performer and its 18A rating seems reasonable. It performs almost as well as the Samsung 30Q down to about 3.1V. At voltages lower than this the R30 could run for a bit longer than the 30Q.
The Vapcell R30 runs hotter than the Samsung 30Q so if you are running these cells continuously I recommend staying below 10A for long cell life.
One of the R30 cells had some corrosion/rusting at the top. In my opinion this means the cell was exposed to some moisture at some point in storage. This doesn’t have to affect safety or performance but it’s never a good thing.
The two cells I tested delivered 3041mAh and 3047mAh. This is fantastic consistency and exceeds this cell’s 3000mAh rating.
Two cells were donated for testing by Vapcell (18650 batteries, Vapcell batteries, 18650 Chargers). Thank you!
