These tests below only note my personal opinion for the ESTIMATED ratings for the batteries I tested at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, EVE, Ampace, Sinowatt, Lishen, BAK, or Sanyo can change at any time! This can be one of the hazards of using “rewrapped” 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 property damage, personal injury, or even death. Never use them outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous discharge rating (CDR), never let it get colder than 0°C or hotter than 60°C to help lower the risks and extend cell life, and keep the plastic wrap and top insulating ring in perfect condition. Never use a battery that is physically damaged in any way.
Testing batteries at their limits is dangerous and should never be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Test Results
The 35E5 is the latest version of the Samsung 35E, performing essentially the same as the earlier version, the 35E3. This version has a “5” on the wrap, at the lower left corner of the printing. If there a “3” or no number at all (35E1, the original model) then it is one of the older 35E’s.
The switch from version 3 to 5 might be due to Samsung increasing cycle life or another characteristic of the cell that doesn’t show up in my basic performance testing.
At 5A this cell performs about the same as the Molicel M35A/P28A/P30B, Samsung 30Q6, LG MJ1, and Murata VTC6. The EVE 35V and Vapcell N41 perform a bit better in testing and the difference might be large enough to notice in actual use.
Some specs and observations…

Some specs and observations…
- This is not a 3500mAh rated cell, even though it’s called the “35E”.
- It has only one datasheet capacity rating, 3350mAh minimum.
- The two cells I tested delivered 3431mAh and 3453mAh. This is pretty good consistency.
- DC internal resistance averaged 30.0mOhms for both cells.
- The datasheet has three charge current ratings; for good cycle life = 1A, standard rate = 1.7A, and the max = 2A. But the datsheet notes that charging at 2A will shorten cycle life.
- For charging I recommend 1.5A max, but only 1A if extending cycle life is a priority.
- This cell has a 2.65V low voltage cutoff, Do not go below 2.65V with this cell.
- This cell has a very low max temperature limit of 60°C. This is easily reached in a wrapped up battery pack or if you’re running a single cell hard. Do not allow the cell to go over 60°C.
- I recommend not going over about 5A to improve performance (minimize voltage sag) and help extend cell life.
