RE: Life battery's
I have a lot more years out of my NiMh battery's, and some should last for more years.
I plan to read the instructions for the A123's and follow the instructions for break-in.
I have read there is a break-in procedure for them.
I have a charger that will charge the LiFe and A123 battery's , if you don't have one you should get one.
