unit into the connector on the battery pack cable. Replace the lid and secure the lid to

Connecting the unit to the rechargeable battery pack
The maximum capacity of the rechargeable battery will decrease over time, also
reducing the overall battery life. The integrated lifetime calculation function built
into the Portable FlowShark Pulse does not compensate for this reduction.
High and low temperatures and long-term use also lower voltage capacity.
Since rechargeable batteries decrease in capacity over time,
replace the battery pack in the Portable FlowShark Pulse no less
than once every two years. Consider a shorter replacement
period under heavy use.
