The problem with what seems to be the majority of the other External Laptop Battery packs out there on the market is that they use cheap low quality 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 External Laptop 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 external laptop 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 External Laptop Battery packs have been designed and manufactured with a PCB (Protective Circuit Board) which provides the following internal protective safety features:

1. Safety protection against thermal run away (overheating).
2. Safety protection against over charging.
3. Safety protection against over discharge.
4. Safety protection against over voltage and over current.
5. Safety protection against short circuit.

Novuscell External Laptop 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 External Laptop Batteries which provide the longest possible laptop runtimes of up to 50 hours per charge.
