Unable to achieve rated capacity

Purchased battery two years ago and it functions well but I have never been able to get 3000mAh from it. The best I have acheived is 1500mAh.
Great product and service

The battery was shipped quickly and arrived in good time. The battery itself was high quality and the wires were in good shape sturdy and great for soldering. the performance i was not able to test exactly but it powers my 24 volt 6.6 amp draw setup with no problems. Don't hesitate if you need a great 24 volt battery you won't be disappointed.
