Really sorry you have not received a reply yet on your question. I have had the same batteries in my T1d for maybe 3 or more months now. But, as you know, it depends on how much you fly, too. I am very pleased with that amount of time. since they are bought batteries. I am still showing a full charge, too, which is amazing.
In my care i flight about 15 batteries times (2 hours) and four baterey leds are on yet... sorry that is not an answer... but "a lot". Ah in about two months.
