This is the good performing Yong De Li New Energy Company YDL 26650D. Aspire owns (partially or fully) this company and it supplies Aspire’s cells. This 26650 is rewrapped by other companies too.
These cells cannot be directly purchased by vapers but I am testing them so I can compare their performance and appearance to what other companies wrap. If another company’s cell looks and performs the same as this one then, in my opinion, we can be pretty sure they are the same.
The capacity for the two cells I tested was 4237mAh and 4264mAh at 860mA (0.2C) down to 2.5V. This is good consistency for a China manufactured cell and meets the 4200mAh minimum rating that YDL gives it.
The “typical” capacity rating from YDL for this cell is 4300mAh so I guess that is why the rewrappers of this cell use that number but, like we saw with Aspire, that number is too high. I am rating this cell at 4200mAh.
YDL gives this cell a 40A “max discharge currrent” rating but in my opinion that cannot be a continuous rating due to the extreme voltage sag and a max temperature of 88°C in my testing…too hot. I recommend staying below 30A and I am giving it a 30A rating.

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.
