The problem with what seems to be the majority of the other CPAP battery packs out there on the market is that they use cheap low quality, short life, lithium-ion battery cells and aren't manufactured using cell balancing technology. Cell balancing allows for the battery pack to simultaneously use all of the Li-ion cells during use, which equates to greatly extended battery pack runtimes per charge and battery pack lifespans. Another problem with what seems to be the majority of the other CPAP battery packs out there in the market is that they are not manufactured using a safe PCB (protective circuit board) design which typically results in battery pack reliability and performance issues such as greatly reduced battery pack runtimes per charge and battery pack lifespans.
An advantage of the Novuscell brand CPAP battery packs is that they are manufactured with the highest quality PCB's and lithium-ion battery cells and cell balancing technology which equates to maximum safety, reliability, super long battery pack lifespans and the longest possible runtimes per charge.
All of Novuscell CPAP battery packs have been designed and manufactured with a PCB (Protective Circuit Board) which provides the following internal protective safety features:
1. Internal CPAP battery safety protection against thermal run away (overheating).
2. Internal CPAP battery safety protection against over charging.
3. Internal CPAP battery safety protection against over discharge.
4. Internal CPAP battery safety protection against over voltage and over current.
5. Internal CPAP battery safety protection against short circuit.
6. Internal CPAP battery safety protection against self-discharge (will hold the charge for over one year when turned off).
Novuscell CPAP battery packs were designed and engineered to withstand extreme altitudes and temperatures and have performed superbly well on professional expeditions to Mt. Everest and the Himalayas.
The Battery Geeks is an Authorized Reseller for the Novuscell Batteries patent pending line of high end Medical-Grade CPAP Batteries which provide the longest possible CPAP, BiPAP and VPAP Machine runtimes of up to 50 hours per charge.
Each CPAP Battery is RoHS compliant and is CE and EMC certified and features internal protection against over heating, over charging and short circuit.
Each CPAP Battery also includes a one year Pro-Rated Warranty. All of our external battery packs are manufactured in the Novuscell Batteries ISO 9001:2000 certified factory and are DOT and FAA approved for use in airports and on airplanes according to the DOT and FAA rules and regulations pertaining to the acceptable transport of Lithium-ion batteries effective as of 1/1/2008. They will also always clear all airport security checkpoints and will never be affected by the security x-rays.
All CPAP Batteries Include A FREE canvas carrying case with a shoulder strap and a One Year Pro-Rated Warranty (extended warranties are also available) + Free FedEx Ground Shipping + A lifetime of free live tech support.
