CPAP Extended Battery Module for HDM Z1/Z2

Breas's Battery Module fits into their Z1/Z2 CPAP Machine. Holding the battery, the module allows the device to be powered for at least eight hours without access to electricity. Part of the world's best travel CPAP machine.

Double The Capacity

With the extended battery, this PowerShell has twice the capacity of the original overnight battery.
Run Time is 8.9 hours (at 20cm)

Makes a Great Backup or Replacement
If you lose the module for your Z1/Z2, or if you simply want a backup, this replacement will seamlessly work with your CPAP device.

Reviewer's Tip:

The battery will not charge if the temperature is over 80 degrees Fahrenheit.  This is a safety feature of the lithium battery.  A fully depleted battery takes up to 10 hours to charge.  Connect all three components when charging the battery:  AC Adapter is plugged into the PowerShell and wall outlet, the Z1/Z2 is inserted in the PowerShell, with the Z1/Z2 on standby mode.

Charge battery periodically if not used regularly.

Advice from Breas after charging your PowerShell:
  • Disconnect the battery from the PowerShell after a full charge to prevent the battery from slowly draining within a 2-3 day period.
  • The battery needs to be charged for 10-12 hours to ensure a full charge.
  • The bars of battery life on the LCD screen need to be full, and not blinking.
  • The PowerShell battery will not charge while it is operating the Z1/Z2 for treatment.  The battery must be charged between treatments.

Does the module come with its own replacement battery as well?

Is there a difference in this battery and the one I can get as the bundle with the Breas Z2?

Both are the same battery. When you purchase the machine and battery as a bundle however you save money!

Does this powershell battery needs a separate charger or can be charged with the same charger from the Z1 CPAP?

You may use the cord from your cpap machine
