To charge the Spire receiver in the field, use a USB-C cable and a vehicle USB adapter rated +/- 5 V DC and a minimum of 0.5 A (or any adapter that supports USB-C power delivery).
Do not charge the Spire receiver from a battery-powered PC or handheld device. Most devices running on battery power do not have enough power to charge the receiver. If it is connected to a device with insufficient power to charge the battery, the red battery LED blinks rapidly.
Note: When Spire is connected to a device with a USB-C cable for data transfer, the red LED may blink rapidly to indicate that the battery isn't charging. This does not affect data transfer.
Maximizing Battery Life
Charge the batteries at room temperature.
Do not leave the Spire receiver connected to a charger for extended periods.
When not in daily use, charge the Spire receiver periodically to 50% power.
If you do not plan to use the Spire for more than a month, charge/discharge the battery to about 50% (the optimal charge level for storage). Periodically check the battery charge level and recharge as needed.
CAUTION: If the battery drains completely, it may not recover and the receiver may need to be sent to Juniper Systems for a battery replacement.
