If you have a Micro-I with a serial number ending between 0000-0900, then it likely contains a battery. *(Your Micro-I serial number is located on the underside of your Micro-I and uses the last four digits).*   Please note we highly recommend using the supplied power cable when using your Micro-I. However, if you need to use your Micro-I remotely ensure you use a recommended battery or power bank.    ### Symptoms of a low or dead battery: If you encounter any of the following symptoms, it may be time to inspect your Micro-I’s battery: 1. **Internet disconnects**: Frequent internet dropouts on your Micro-I could indicate battery-related power issues affecting the onboard systems. 2. **Red battery status**: If the battery status on the portal appears red, it signals that the battery is either depleted and requires charging or has malfunctioned. 3. **Lights not turning on**: In some instances, the lights inside the Micro-I won’t illuminate or will remain in a solid yellow or flashing white state.   ### How to remove the battery: Follow these steps to remove the Micro-I’s battery. Note that a screwdriver is necessary for this process: 1. **Power off**: Turn off and unplug the Micro-I. 2. **Turn Micro-I over**: Locate the battery compartment on the underside of the Micro-I. It is situated next to the single foot to the right of the serial number sticker. 3. **Identify the screw**: Find the screw holding the lid of the battery compartment. 4. **Open the compartment**: Loosen the screw to open the compartment. 5. **Remove the battery**: Take out the existing battery. 6. **Secure the Lid**: Screw the lid back in place. **Consider using a battery pack:** We recommend utilising a battery pack while working in the field which can be used to log submissions in offline mode.  ### Battery pack recommendations: - Ensure the battery pack features a **5V output port** (minimum), ideally with **3.0 amps or higher**. - Choose a power bank with a capacity of **15,000mAh or greater** to support all-day operation under general conditions.   ### Battery replacement: If you opt to continue using the current battery, please be aware that it may affect the Micro-I’s performance over time. Replacement batteries are available for purchase at local hardware stores. Recommended battery specifications are: - **Battery Type**: 18650 Li-Ion Rechargeable Battery - **Voltage**: 3.6V - **Capacity**: 3500mAh - [General Questions](https://help.fecpak.com/en-nz/general-questions?hsLang=en-nz#main-content) - [Support Hours](https://help.fecpak.com/en-nz/general-questions?hsLang=en-nz#support-hours) - [RATA Platform](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#main-content) - [Releases](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#releases) - [Networking](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#networking) - [Power](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#power) - [Submissions](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#submissions) - [Portal](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#portal) - [Major Incidents](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#major-incidents) - [Cassettes](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#cassettes) - [Account Management](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#account-management) - [Sample images](https://help.fecpak.com/en-nz/rata-platform?hsLang=en-nz#sample-images) - [FECPAK Connect](https://help.fecpak.com/en-nz/fecpak-connect?hsLang=en-nz) [![FECPAK\_Logo\_Blue](https://help.fecpak.com/hs-fs/hubfs/FECPAK_Logo_Blue.png?width=306&height=80&name=FECPAK_Logo_Blue.png "FECPAK_Logo_Blue")](https://help.fecpak.com/en-nz?hsLang=en-nz) Copyright © 2026, Techion Group Limited | [Privacy policy](https://fecpak.com/nz/privacy-policy)
