Battery holder contact resistance measurements

I finally got some battery holders from digikey that I have been asked about several times.

BK-18650-PC2
BH-18650-W
BK-18650-PC4

Here are the results

BK-18650-PC2 Single Contact = 7m?
BH-18650-W Single Contact = 2.6m?
BH-18650-W Single Contact W/24g Wire = 16.4m?
BK-18650-PC4 Single Contact = 9.7m?
Keystone 1043/1049 Single Contact = 1.2m?
Keystone 1042/1048 Single Contact = 1.2m?

Keystone is still the winner :D

Nice going

So how does this work, you are measuring the resistance of the tab material from where the battery makes contact to the far end that the wire gets soldered to?
What if the soldered wire is very close to the point of battery contact. Would that bring down the resistance?
