Title
Eufy HomeVac H11 Battery Replacement
Introduction
This guide is for the disassembly and subsequent battery replacement of the Eufy HomeVac H11
Warnings/disclamers:
* The manufacturer states that the battery [link|https://support.eufy.com/s/article/Is-HomeVac-H11-battery-replacable|isn't replaceable|new_window=true]
* The manufacturer states that "There are no user-serviceable parts inside." (see [link|https://support.eufy.com/s/product/a085g000000Nm4vAAC/homevac-h11|user manual|new_window=true])
* This guide applies to the HomeVac H11 only (NOT for H11 Pure)
* Following this guide is at your own risk and will most definitely void the warranty
* This guide requires soldering skills and tools
* Depending on the tools used, following this guide may damage the device's exterior
* The photos in this guide are from after I've replaced the batteries. So the batteries you can see there are not the original ones. Also the exterior damage is much worse than can be. I did the disassembly with zero knowledge of how to do it correctly and not with the best tools initially.
Tools needed:
* Replacement 18650 (unprotected) batteries. Protected ones can be used, but need the extra step of removing the protection circuit.
* One (two recommended) flat-headed tool to pry open the device. The wider and sharper the better. I used a wood chisel. Having two chisels is recommended but a flat-head screwdriver can be used too.
* Soldering iron; solder; flux; solder wick (recommended)
* Optional: spot welding pen
* ~10 cm of copper wire or nickel strip
