Headway factory box

[gartmu]

I made a order of several Headway batteries (38120S 9Ah and 10Ah ; 38140S 12Ah). When they arrived I can´t figured out which of the 38120S were 9Ah and 10Ah because they look the same. I looked more closely to the boxes and found some stikers with chinese characters and numbers.
I think the numbers are related with the battery capacity interval of the 8 cells that came in that box. This is a good thing to make a better balaced battery . What is strange is that some 9Ah batteries I bought some months ago are rated 9450-9500mAh and the ones I bought now are 10300-10350mAh. The 10Ah are rated 10800-10850mAh. The supplier is now reporting the 9Ah is out of stock and some of the boxes that came have the stickers removed. I think the supplier is selling the 10300-10350mAh has 10Ah, I will confirm this with some capacity tests.
Are my conclusions true? Can someone translate the stickers? Does anyone ever noticed these stickers and what do they mean?
Please help.

First line is capacity and then the second line is internal resistance.

I've been thinking about buying some headways cells for a new pack. Can you tell me where you ordered from? How did you get direct shipment?
thanks

I bought them in BMSBATTERY they work very well and ship fast, you can trust them. Their prices are good.

First line is capacity and then the second line is internal resistance.

Thanks. Valuable information.

I thought headways were denoted by dimensions, i.e 38120=38mm diameter cylinder by 120mm long, so in your case i would have thought the 38140 12ah were 20mm longer..
my headway 42160 16ah are 42mm by 160mm long....
I am a bit of a noob at battery tech..but this is my understanding..
