This is a decent performing cell that will give you more vaping time than the 4200mAh-4300mAh 26650’s if you are at around 10A/30W or lower. This cell might have a 20A rating (about 60W) but at power levels over 30W or so this cell’s higher internal resistance leads to greater voltage sag. That means less vaping time before the voltage drops too low.
For example, this cell delivered an average of 834 two-second puffs at 30W compared to the (roughly) 770 puffs delivered by the cells that wrap the 4200mAh YDL 26650D. But at 60W this Vapcell only delivered 210 puffs versus the over 300 puffs delivered by the YDL-based cells like the Golisi, Aspire, and Vapcell 26650’s.
Note: This performance comparison does NOT include the poor performing, and preposterously overrated, Efest 35A/50A 4200mAh 26650.
The capacity for the two Vapcells I tested was 4961mAh and 4998mAh at 1000mA (0.2C) down to 2.5V. This is good consistency for a China manufactured cell but these cells did not meet their 5000mAh rating. I am rating this cell at 4900mAh.
Yes, the one cell tested at so close to 5000mAh that it essentially met its rating, but the other did not. I feel any capacity rating should be a guaranteed minimum, not a “typical” or “nominal” rating. A cell rated at 5000mAh should deliver, on average, at least 5100mAh so that any cells that are not quite up to the capacity of the others in that batch can still meet their 5000mAh rating.
Two cells were purchased for testing by me.

I want to work for the vaping community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: https://www.patreon.com/batterymooch.
These tests 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” batteries 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 protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Any rating in my ratings tables can change at any time as different grade cells appear on the market, we get swamped with fakes, or new information becomes available to me. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.
