Recharge Capacity vs time in service

For fixed large installations the ZBM should be superior performance over the long haul and have therefore longer service life and reduced total cost of ownership long term.

Lithium battery loses capacity over time and needs replacement more frequently - total cost of ownership over the long haul would put ZBM in front if the replacement frequency is say half that of lithium batteries.

We need proven long term commercial service to demonstrate it....patience needed.
