Puritan Bennett 540 Battery Replacement

Introduction

If you need to replace the battery of the Puritan Bennett 540, use this guide to access the battery from the rear end of the device. You will need a Torx T10 screwdriver to remove the battery cover and will need to have a 25.5V lithium-ion battery ready for replacement. There are no difficult steps, but be sure to be careful with unscrewing the cover and make sure you keep track of all of the screws, as you will need them to put the device back together.

The ventilator must be disconnected from all external power supplies and be turned off during this operation.
Batteries should be disposed of according to environmental legislation in your country and locality.
Never expose any batteries to direct flame.
Never touch the ventilator’s internal components, including the battery, and the patient simultaneously.
