Hi All,
I already share the following data in a Taiwanese forum, so there is watermark on the pictures~
http://www.wii.tw/~fogerdis/viewthread.php?tid=48943&page=1#pid253384
Not using a very professional equipment, the impedance meter is named "ZY05L" :
http://www.aliexpress.com/item/ZY05...ltmeter-nickel-metal-hydride/32371737562.html
It uses Kevin clip 4-wires AC sensing, so I think the results still comparable between all the batteries.
Last thing is I use the GW Instek GTL-108A test lead.
Sorry for my bad English .......
Any comments and suggestions are welcome !!
Update:
I'll try to find the datasheet or dealer's description of all the batteries:
As you can see, although it's not really useful for the "DC" application,
the internal impedance value measured by my setup is close to the datasheet or dealer's description.
10/3 Update:
Got 4 AA NiMH speical design for Mini 4WD racing,although the capacity is small (1600mAh),
but the 1kHz impedance is really quite low (only 4.8mΩ) !! Even lower than Li-ion batteries.
