Sounds odd to me as well. sounds like the battery might be running to may cycles that could possibly shorten the life span.

Replacing the battery won't be cheap either, I have heard upwards of $9000 to replace them.

I believe that the update will allow the battery to run down 27% more before the engine kicks in to recharge it. This lengthens the time between engine starts & stops, saving fuel. And rather than increasing the number of charging cycles, it will actually reduce the number. What impact, if any, the 27% deeper discharge will have on battery life has not been mentioned.
