I bought this battery to use for QRP (low-power) amateur radio use. My rig's typical duty cycle is 50mA idle, 450mA on transmit. Using computerized battery testing software/hardware, I took this battery from a full charge down to 8.5V to better understand its capacity before I went out in the field with it. With the aforementioned duty cycle, it registered 2417mAh. Not the full capacity, but not too far off either.For my use case, it's perfect, giving me over 10 hours of radio fun on a single charge, in a tiny self-contained package -- and so inexpensive! Highly recommeded for QRP ham radio use.
