I bought some for flashlights and checked capacity.2800 mah according to my tester.I bought from the "official store"lots of fake sites

Are they labeled as: "136", "141", "6T" or "6.150 T"

I should have added.5 cell's cost $11 USD

At $2.20 ea they could be outdated "136" or "141" manufacturing runs that have been in storage for several years. Could be why they test 2800mAh instead of 3000mAh. Better to use at only 90% charge (4.1v) with LVC no lower than 3.0V instead of 2.5V for extending cycle life ALAP. If-when doing a full charge (4.2V) do not store more than a few hours before use for cycle life longevity. If a 5 cell flashlight only charge to 20.5V (90%), instead of 21.0V (FULL Charge).

You should get your money's worth if you only charge to 4.1V majority of the time and never discharge lower than 3.0V (bounce back voltage should be at least 3.2V to 3.5V for cycle life longevity. If the label doesn't say "136, 138, 141, 6-T or 6-150-T" they are not genuine Grade A Samsung cells.

When in storage (say 3.60V) periodically check to see if there is any self discharge after a couple weeks. If so recharge to 3.60V).

Apparently these fakes have been around for at least 5 years, as here's a review from 2018, His conclusion said as long you don't go over 3-5A per cell, they were a good buy back then, Still, they're not 30Q's not iof you can't get 10A out of them..

Today, you can buy name brand cells like Eve for under $2/cell and they are capable.

I have had good luck with real 30Q's, Seem to have good longevity, I like the 15A rating. While price varies from day to day, the current pice on 6/14/2024 is like $3,50/cell, That's as low as I ever seen.

Labeled 136.They actually had 2865 mah but I thought that was pretty good.Do you think 21700 batteries would be newer and this higher capacity?

Yes ... newer and higher capacity .(and higher cost if they are A grade name brand cells). These $2 Samsung 30T(?) cells ... https://batteryhookup.com/products/new-samsung-30t-21700-3000mah-35a-power-battery ... would have been a better buy (longer cycle life) than those "136" cells. No way of knowing for sure if they are authentic A grade Samsung 30T cells, but still better buy than those outdated "136" cells.

Those unused "136" cells may still be worth using even though outdated and questionable A grade cell. No way of knowing if they are worth $2.20 depending on their intended application.

Thanks for the link.Free shipping for the battery from AliExpress.

I've discussed about this before on BudgetLightForum, but any non Chinese cells from the Liitokala store are fake and likely stil lare fake to this day.
