Bench Test Results: Genuine Sherlock Hohm 28.4A 2782mAh 20700 Battery Ireland

25A battery, performs between iJoy 4-leg and 5-leg top contact 20700’s

Bottom Line: This is a battery that runs at close to 90°C at its 28.4A continuous rating. This is too hot in my opinion for decent cycle life as most cells, including all of the others from Hohm Tech, say not to exceed 75°C-80°C. When the datasheet becomes available I will be able to check its max temperature rating.

The Sherlock Hohm battery performs worse than the 5-leg top contact 20700’s but better than the 4-leg iJoy 20700.

The two cells I tested delivered 2760mAh and 2761mAh at 0.5A down to 2.5V. Considering the differences in the equipment used by Hohm Tech and I these 20700 batteries can be considered to have met their 2782mAh capacity rating.

The Terms & Conditions section of Hohm Tech’s web site says that their cells are not meant for use outside of a protected battery pack or in a device without equivalent protection. This means no unprotected mod or mechanical mod use of their cells is supported by Hohm Tech. For vendors this might affect the warranty in certain situations. Contact Hohm Tech for more information about this.

I was very disappointed to see “47.8A” featured in a large font on the cell, with nothing to indicate what it meant. This is the pulse rating, which Hohm Tech defined for me in emails, but

Hohm Tech says that vapers should not use this pulse rating for anything. They said we should only use the continuous discharge rating…and I agree.

The continuous discharge rating is also on the battery, and is marked as “CDR”, but uses a smaller font. Hohm Tech said that in December 2017 they decided to switch the sizes and positions of the two ratings on the wrap. I don’t know if these new wraps are being used yet.

I am estimating the ratings for this Sherlock Hohm cell to be 25A and 2782mAh. The 25A rating helps to keep its temperature down closer to the 80°C limit for other batteries.

Two 20700 batteries were donated for the purposes of testing by Hohm Tech – Thank you!

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, LG, Panasonic, 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 the tables can change at any time as different grade cells appear on the market or we get swamped with fakes. Please, never assume that the ratings in the table are permanent and will never change! Always download the latest version before considering any cell purchase.

  1. I just bought two of these for my Pulse 80w, haven’t used them yet, do you have any experience with them?
