Cell Database Submissions and Updates

Here are some images of SE US18650VTC6.
I bought these as new and they capacity test to 3000mAh and weigh in at 46.5g, so I'm sure they are genuine. Smile

Hi I'm knew here and not allowed to sub the post I wanted to until I post abnormal postbox first. There's an unknown Dad blue 18650 in your list of batteries with photos that the most similar to the one and I have found.  I will add photos on the unknown battery in the list to see ignorance anyone can help me identify the spec sheet of them. 
Thanks 
Tim

I have these battery's but can't find any specifications for them. Can you help?
Measured capacity from 10 calls is between 2168mAh and 2292mAh 
 


Most similar cell, by looks, from your cell database is last one YikLik (YLE) INR18650A220

I have four of the cells shown below. They came from a single laptop pack and have the following characteristics measured using an Opus BT-C3100:

Capacity approximately 3000 mAh
Terminal voltage when charged 3.62V
Internal resistance 100 m Ohm
The cell marking is LGABC 41865
0282J098A9
Covering is brown. End cap insulator is white.
 
Ideas?

Thanks Simon

Agreed they look like the cells in the datasheet. I am still puzzled by the end point voltage. All the other cells I have measure 4.2V. These all measure 3.62V. I have used 4 different meters and they all agree.

So are they good or bad?

Sounds like they are toast to me, I've never seen cells end this low.
Probably worth starting a new thread with this question, better exposure and won't be dragging this one further off-topic.
