Rent to own your gear!

Do you love the gear you rented? Great news we here at the battery geeks will apply your rental rate toward the purchase of a brand new battery! Rules and Restrictions:

  • You can keep the gear you used for the rental (often new) or send back rental for brand new gear
  • The rental rate will be applied to and for the equal purchase (i.e. if you rent a battery and a solar panel but only purchase the battery you will only be credited for the battery rental)
  • You have 30 days from the day we receive the rental gear back at the warehouse to use the rental credit for purchase
  • Credit can only be used from the most recent rental
  • Note* If you decide to keep your gear and an inverter was included with your rental you must purchase it separately

Rentals kept beyond 60 days will be considered "purchased" and are not eligible for rental return, exchange, or refund of deposit.

What is an Inverter?:
An inverter is a small device that converts DC power to AC power; for appliances that can not use DC power directly. An inverter plugs directly into a DC power source and provides AC (wall type) outlets just like those you are familiar with in your home.   [DC power: Battery;  AC power: Wall plug]
How do I know if I need to use an Inverter?:
Only the custom Inverter that we supply is guaranteed to work properly with our battery packs. The N-C20000 Battery Pack includes a DC-Out cable that can be used with multiple machines including the Respironics M-Series and System One Series devices, and all DeVilbiss IntelliPAP devices. However, ResMed machines, and Fisher & Paykel machines require the use of an inverter. Ask your CPAP provider if your machine can receive DC power.  If your machine can only receive AC power; (like from the wall outlet), then you will need use the Inverter included in your rental order. 

Because the Inverter keeps the voltage from the battery constant, some DC compatible machines may get more run-time with the Inverter, even though they are able to receive DC power.  We suggest trying your DC compatible CPAP to Battery connection with the Inverter, & then without the Inverter to determine best run-time.
>>Multiple factors will effect run-time, including but not limited to: machine make & model, pressure settings, altitude, use of humidifier, and use of an Inverter (20% or more loss for each factor).

>> IMPORTANT: CPAP Manufactures specifically DO NOT recommend the use of the Humidifier with a Battery. Although a Humidifier can be used, run-times will be significantly lower than expected.
