Bench Test Results: DLG INR18650-320 – 6.4A 3200mAh 18650…about equal to the LG MJ1, lower cost

Test Report Summary: This is a an averaging performing high-capacity cell, about equal to the LG MJ1 down to 3.2V. The Molicel M35A and Sanyo NCR18650GA perform a bit better but this cell should be available at a lower price which could make it the better choice for cost-sensitive applications.

While the datasheet gives it a 6.4A continuous current rating and a 9.6A temperature-limited current rating (never let it get hotter than 60°C) I recommend staying under 5A or so to reduce the amount of voltage sag and to increase cell life. This is my standard recommendation for any over-3000mAh 18650.

The two cells I tested delivered 2894mAh and 2919mAh, failing to meet its 3000mAh minimum capacity rating. I am rating them at 2900mAh.

Two cells were purchased for testing by me.

I want to work for the 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: Battery Mooch is creating battery and device tests | Patreon.

These tests only note my personal 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” 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. They are not supposed to be used outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

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.

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.
