GPS locations sent during Alarm Mode are the main factor draining the batteries. With this in mind, you don't want to have many false alarms. Avoid moving the Monimoto when the Key Fob is away.
IMPORTANT: Enabling "Include location with regular ping" in device settings, also drains the batteries faster as the device will attempt to send an additional location with each regular update ping.
If in constant alarm mode and in-motion the unit will attempt to send a location every 5 minutes and this will drain the batteries in 1 week. In 'Live tracking' mode, every 10 minutes consumes 1% of battery. Use this mode only when you want to track your device more frequently during emergency situations.
