The transmitter pack that I just purchased, cycled the second time at 880Mah This is a 700mah pack made by Maxx. They use Sanyo cells in their packs. When I cycle I go right from trickle to discharge. This will give you a slightly higher reading than if you let the pack rest for a period of time before starting the cycling process. When my packs cycle at the same or less capacity than the pack is rated at, it is about time to replace it
If your packs cycle at less than the rated capacity, I would take them up on the pack replacement.
