AW IMR Battery Dimensions

[Matt M]

All,

I'm currently designing a hybrid PV and I was wondering if anyone knew what the manufacturing tolerances are on AW battery dimensions? What are the ± figures for the physical dimensions.

The no-name 18500s that I have are upwards of 18.2mm DIA and 49.9mm long.

The dimensions are in the name itself.
18mm diameter 50mm length. 0 at the end stating that is a cylindrical. That extra .2mm is the button top I'm guessing. Are you asking for precise measurements for each brand? And size

Hope that helps.

Woops just realized that your 18.2 is on the diameter measurement.

I understand the Ø18 x 50mm part. Its the tolerances that I want. I.e. Ø18±0.2mm

I measured my AW IMR 18650 1600ma-h and got diameter 18.2 mm

Thanks for that.

If anyone is interested, I got an email back from trustfire and their tolerances are ±0.2mm on the diameter, and ±0.5mm on the length.

I've been asking myself the exact same question these last few days... thank you Matt for asking, and for coming back with a response from Trustfire... I may be able to sleep now
