how to check your battery is original?

how to check your battery is original?
you can check the value of internal resistance.

The internal resistance of the battery is an important parameter to measure the discharge performance of the battery.

Generally speaking, the lower the internal resistance of the battery is, the higher the discharge current of the battery is.

The resistance of the battery need professional instrument test, and the multimeter can only directly test the resistance of the uncharged metal.

Here are some of the internal resistance tests for 100%original high drian batteries

sanyo NCR20700A (8.96mΩ)

LG HG6 (9.26mΩ)

Sanyo NCR20700B (13.66mΩ)

Samsung 30T (6.77mΩ)

LG HG2 (13.89mΩ)

Samsung 25R (12.74mΩ)

Sony vtc5A (9.87mΩ)

Sony vtc5 (12.75mΩ)

Sony vtc4 (11.94mΩ)

Sony vtc6 (12.83mΩ)

LG HD4 (11.38mΩ)

Samsung 20RM (12.72mΩ)

Samsung 30Q (12.78mΩ)

LG HE4 (12.77mΩ)

Sanyo UR18650NSX (13.01mΩ)

LG HB6 (11.18mΩ)

Samsung 35E (21.9mΩ)

LG HE2 (13.77mΩ)

LG HB2 (11.22mΩ)

Sanyo UR18650RX (11.66mΩ)

LG HB4(10.97mΩ)

Samsung 48G (14.09mΩ)

Sanyo NCR20650A (9.58mΩ)

awesome

I buy my batteries at https://www.imrbatteries.com/ for peace of mind. All original, never fakes.

buy them from fogstar you no they are gen then...............

using the xtar dragon with 30Q im getting 4.17v 15mΩ

so how does that compare to your readings 3.65v 12.78mΩ @Ewald Andre

I don't have any 30qs to test but from what I've read batteries internal resistance can grow as they age

I certainly get higher readings on my old 25rs VS my new set, but the old ones have almost 6 months of heavy use and the new ones have only got a few cycles on them so far

Thanks for the reply. The 30q are only 3 months old but I will try some of my 2 year old 25r to see how they compare to above.
Only checking really as got to try out the new dragon. It is not to test if they are real like original post as I know they are.
