Are there any options for a replacement 18650 Battery for the GMC-500+. I normally keep the unit plugged in, but when it loses power, the battery only last 10-15 Minutes. I can see in the battery status page that it goes down pretty quickly when it is unplugged. I would love to have a couple of spare batteries for this unit if there was a recommended replacement.

hi johnp65, you can buy any standard 18650 li ion 3.7V battery for replacement. If your battery drains completely, check the charging circuit to see if it still works by measuring the voltage between the + and - terminals while device is charging and no battery.
