This appears to be a rewrap of the Murata VTC6, rated at 15A continuous by Murata, but the Orbtronic cells performed a bit worse than a Murata VTC6.
The VTC6 has a “temperature-limited” rating of 30A if you do not let it get hot, over 80°C. You can use it at up to 30A but at above about 17A-20A you could get more run time from the more efficient 25A cells like the Molicel P26A and the Sony/Murata VTC5A and VTC5D. This is because there is less voltage sag with these higher performance cells and that means the voltage stays up for longer when being used hard.
One issue I have with this Orbtronic cell is that the wrap has a big, bold “30A“ on it and only in the tiniest lettering can you see that it‘s not a true 30A cell. You cannot use that 30A rating to compare this cell to any others that just list their true continuous current rating!
The 40A “max pulse“ rating on the wrap is just something they made up. It’s not listed in the VTC6 datasheet and there is no standard for setting a “max pulse” rating. It cannot be used to compare these cells to any other cells.
The VTC6 has a rated capacity of 3000mAh and a nominal (typical) capacity of 3120mAh. While the capacity rating that Orbtronic uses is the nominal rating for the VTC6 be careful when using this 3120mAh rating to compare this cell to any other one. Other cells typically use the lower rated capacity number, as they should since it is a guaranteed minimum capacity.
The capacity of the two cells I tested was 3090mAh (below Orbtronic’s rating) and 3122mAh. Since the two cells I tested cannot be the lowest capacity Orbtronics out there I am rating them at 3000mAh, the rated capacity of the VTC6.
I am very disappointed to see that Orbtronic seems to be playing the same ratings games as some China battery wrapping companies.
This Orbtronic cell uses a paper top insulating ring so I recommend not allowing it to be exposed to any liquids as they could be absorbed and cause rusting under the ring. Paper rings can be more resistant to extreme heat though than plastic insulating rings.
Two cells were purchased for the purposes of testing by me.

I want to work for the vaping community full time!

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 and you use them AT YOUR OWN RISK. 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.
