Spytec M4 Pro Extended Battery and All-Weather Case - User Manual
Step 1: Charging the Battery
1. Plug the round connector from the
cable on the AC adapter into the larger
round socket of the lithium-ion battery
pack cable. Plug the adapter into a
wall outlet or power strip. To fully
charge a zero-charged battery, plan
on keeping the charger plugged in for
up to 15 hours. The LED on the power
adapter is red during charging and turns green when the battery is fully charged.
2. When you unplug the adapter from a power outlet, but it’s still connected to the
battery, the LED will be green. This means the battery is powering the LED, but it
does not indicate whether the battery is fully or partially charged. Store the power
adapter separately since it will not fit in the case along with a GPS tracker.
Step 2: Connecting the GPS Tracker
• Connect the connection cable
to the battery pack by plugging
the 4-pin connector on the cable
to the 4-pin plug on the battery
pack. The plug will only fit one
way. Once connected, plug the
other end of the connection
cable (mini-USB or USB type C)
into the GL300. Once the tracker
is powered on, it will draw power
from the battery pack.
• Note:
The external (extended battery) will NOT charge the tracker’s internal battery.
For the most long lasting power, you should fully charge the tracker’s internal
battery separately before connecting the fully-charged extended battery.
