Test/Review of Panasonic/Sanyo NCR18650GA (3450mAh, 10A), comparison with Samsung INR18650-35E and LG INR18650 MJ1

This cell is commonly sold as “3500mAh” cell, and Olight even make a “3600mAh” protected battery with it.
The datasheet says:

- Rated Capacity: 3300mAh (0.67A discharge at 20°C)

- Capacity (Minimum): 3350mAh (0.67A discharge at 25°C )

  • Capacity (Typical) 3450mAh (Reference only)
    It’d probably be better to call it a 3400mAh cell.

Are you HKJ’s apprentice? :bigsmile:

Thanks for the details. Really well and clearly presented in the graphs.

Great info.

Thank you Very Much,

George

Nice graphs! Thanks!

Interesting, i had no idea the GA was a “fake” 3500mha cell. Very good to know i will consider it a 3400mha cell from now on.
And also the olight 3600mha info, i hadn’t heard about it before.
I asked hkj to review that because i thought it could be the elusive pana 3600mha cell inside, don’t know if he will though & if it is really only a GA rewrap it is not really interesting anymore.

Can you post a comparison on all the amps you tested with the LG MJ1?

Thanks for posting these graphs.

Panasonic/Sanyo NCR18650GA does show less voltage sag than the Samsung INR18650-35E and LG INR18650 MJ1 in the 5-10 amps area. Probably making it a good use in direct drive and triple/quad builds were we actually want some run time also.

So looking at there voltage sag and amp draw you can see which cell has less internal resistance, right?

NCR18650B is and was a weak cell for this hobby, the graph shows exactly that.

many thanks for your effort light-wolff :wink:

Thanks! Good to see the Panasonic is still somewhat holding up against newer cells despite being released several years ago.

Very helpful, thanks for posting it. Missed it earlier.

Thanks for a very informative comparison between these similar cells.

Thanks for your efforts,

Es war sehr hilfreich, mich in die Ernte der GA über die Mj1!

And where in China you can buy the original Sanyo NCR18650GA ?

Another question, maybe today there is already better than Sanyo NCR18650GA?
