64 -
65 -* **Charging Duration**: Both types of nodes take approximately 6-8 hours to fully charge from a flat state.
66 -* **Pre-Deployment Charging**:
67 -** Although the nodes hold their charge well, it's beneficial to give them a "top up" charge right before deployment.
68 -
69 -* **Operational Duration**:
70 -** When recording at 250 Hz, with GPS on and Bluetooth disabled, the instruments are expected to last about 30 days per charge cycle.
71 -
72 -* **Post-Retrieval Charging**:
73 -** Do not store the instruments with completely drained batteries.
74 -** After retrieval, charge the instruments to about 50-60% (indicated as "orange" level) for optimal battery health.
75 -
76 -* **Storage and Shipping Charge Level**:
77 -** Maintain a battery charge level of around 50-60% for both storage and shipping purposes.
