These tests below only note the ESTIMATED ratings for these batteries 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 personal injury or property damage. They are not meant to be used outside of a physically and electrically protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition. Use of any of these batteries is AT YOUR OWN RISK.
Testing batteries at their limits is dangerous and should never, ever, 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 accuratelly rated and performs essentially the same as the Samsung 25R. It appears to be a cell from one of the smaller China factories.
I don’t know how the cycle life of this cell compares to the Samsung 25R but Vapcell says this cell should be available at the same price or perhaps for even less than the 25R. This is good news because cells from the bigger manufacturers will be harder and harder to get.
The two R25’s I tested delivered 2573mAh and 2574mAh and meet Vapcell’s 2500mAh rating. This is fantastic consistency and is typical for cells from the big manufacturers, not the smaller China factories.
The Vapcell R25 runs a little cooler than the Samsung 25R and this cell’s 20A rating seems reasonable. If you are able to find it for the same price as Samsung 25R’s then you might consider giving this Vapcell R25 a try.
The 35A max rating is preposterous and useless, ignore it. In my opinion it was set in a marketing meeting, not a test lab, to try to make this cell more competitive in a market flooded with exaggerated current ratings.
Two cells were donated for the purposes of testing by Vapcell (18650 batteries, Vapcell batteries, 18650 Chargers). Thank you!
