Introduction

If your Hamilton G5 Ventilator has battery warnings, use these steps to replace either the internal or extended battery. The internal battery is 12V/120W, while the extended battery is 11-14V/95W. Before replacing a battery, it is important to run checks to ensure they do need to be replaced. Be cautious, as there is a large amount of power in them and there are many small parts involved. Before starting, make sure the ventilator is powered off and unplugged. To replace the battery, you will need an Allen Wrench.

For more information about replacing the battery, please refer to section 10 in the service manual.
