These tests below only note my personal 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, 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, 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
It’s been 4-1/2 years since I last tested this cell so I thought it was worth seeing if the performance has changed over the years. The VTC6’s I tested performed a little better than the ones I tested in 2018. You probably won’t notice the difference but it’s good to see.
The datasheet mentions operation at over 15A if you keep the maximum cell temperature below 80°C but I recommend not using it at over 15A. This is an “energy” cell and not a “power” cell and you start getting a lot of voltage sag when running near its 15A rating or higher.
Two cells tested out to 3113mAh and 3123mAh, which is great consistency and is typical for Murata. Both exceeded their 3000mAh rating. I have not tested the cycle life of these cells.
These were purchased for testing by me from 18650BatteryStore (18650 Battery Store - Lithium Ion Batteries, Chargers and Accessories).
