This is an accurately rated cell that performs essentially the same as the Sanyo NCR20700A and a touch better than the Molicel INR-20700A. I don\u2019t know if you\u2019d see the difference when using any of them though.<\/p>\n

This cell uses the same \u201cchemistry\u201d as LiPo cells. While this chemistry is not \u201cdangerous\u201d it does react more violently and at a higher temperature if the cell goes into thermal runaway from being badly abused or short-circuited. This Hohm Tech cell has passed the basic safety tests though.<\/p>\n

The capacities for the four Sherlock Hohm 2 cells I tested ranged from 3154mAh to 3195mAh at 620mA (0.2C) down to 2.5V. This is decent consistency. I am rating it the same as Hohm Tech did, 3116mAh.<\/p>\n

This cell has a 41.3A \u201cmax\u201d rating in larger print on the wrap, which I am very much against. Hohm Tech is in the process of switching over to a wattage-based ratings system though and will not be making their \u201cmax\u201d ratings the biggest numbers on the wrap. This should be happening over the next couple of months for all their cells and I welcome the removal of these large print \u201cmax\u201d numbers.<\/p>\n

The new wattage-based ratings system, when fully implemented, could make things easier for new vapers to choose the Hohm Tech cell that best fits the way they vape. But it means they might not learn about current ratings and other things they will need to know if they use any other company\u2019s batteries. I\u2019m torn as to whether it is a good idea or not. I look forward to seeing how the community reacts to it.<\/p>\n

The \u201cmax\u201d ratings are temperature limited to 80\u00b0C. This means you could potentially use this cell at up to its 118W\/41.3A rating if you don\u2019t let it get hot. While it is possible to go that high with this cell it does not lead to good performance and your vaping time will be short. I recommend limiting use of any cell to its continuous current\/power rating or lower. This reduces risk, increases overall cell life, and improves performance.<\/p>\n

Some of the ratings on the wrap are still printed quite small, in orange on a darker orange background over another patterned background. This makes them hard to read, reducing their usefulness to vapers.<\/p>\n

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<\/a>.<\/p>\n

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 \u201crewrapped\u201d batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.<\/p>\n

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\u2019s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.<\/p>\n

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.<\/p>\n
