I have a CubeCell dev board (HTCC-AB01) running a simple test.
It transmits a fixed 3-byte uplink message (without any further processing) and the RGB LED is enabled so the LED lights with each uplink message.
So far it has sent more than 72000 uplink messages on a single battery charge already.
A 1200mAh LiPo battery is used as power source (true capacity is probably more like 1000mAh).
The CubeCell board has sent 72000+ uplink messages already on a single battery charge (and running). Battery voltage is still 3.69V so maybe 100k messages on a single charge will be possible.
(For this test battery voltage is measured manually, and not measured automatically by the node).
Update:
I lost track of the exact uplink message count and later noticed the battery was empty.
Based on my last counter check (80+k) and some extrapolation:
A total of between 90k and 100k uplink messages have been sent on a single battery charge.
