Thanks everyone. Mainly I wanted to show the performance difference between an HF 17AH pack and a domestically made 18AH battery. I knew about the 20hr rating being at a much lower current draw, but would have expected these two to measure close and if anything the 17AH pack, meant for a jump pack, to have lower internal resistance/higher AH's delivered under the same load.

Also: Batteries are designed differently depending on their intended use. Those jump packs are designed to provide very very very high current, 17 Amp Hours sounds like about a 750 to 900 amp peak pack.
Looking around Amazon, I see puny little 12V 7AH batteries in the 750-900A peak jump packs.
This one for instance.ReviewThis one likely has a 18AH'ish pack inside and is '1700' peak amp.
That's marketing for you.
