Finally, improved battery life is here.
BatteryOS technology.

BatteryOS is a new way of controlling energy inside of existing lithium-ion batteries, enabling them to hold more capacity and keep working like brand new after many years. BatteryBox is the first device to be powered by BatteryOS.

The problem: You've never
charged a battery to 100%

There's a rule in the battery world; the closer a lithium-ion battery is charged to full capacity, the faster it will degrade.

For this reason hardware manufacturers almost never fully charge their batteries. They set an artifical limit on the charge inside - this means when your battery indicator shows that it's at 100%, in reality the actual charge is at a lot less -anywhere from 50% to 95%. This kind of limitation occurs in all devices, ranging from smartphones to electric vehicles.

BatteryOS is a new way of controlling energy inside of existing lithium-ion batteries, enabling them to hold more capacity and keep working like brand new after many years.

Lithium-ion batteries get charged and discharged through a constant stream of energy, usually without any attention given to internal or external circumstances. This ends up causing many problems, ranging from passive SEI layer formation to internal polarization, causing the battery to not fully utilize it’s active materials and to degrade over time. The BatteryOS system is designed to dynamically manage energy inside of a li-ion battery pack during charging, idling, and discharging of the pack.

This enhanced control method allows any OEM li-ion battery to gain the ability store 10-40% more capacity (varies between specific type of li-ion chemistry), have a 4x higher cycle count, and only degrade minimally in capacity over time.

Capacity degradation

Test Methodology

An accelerated aging test was run under 65C (149F) in a temperature chamber to compare the calendar life between 2 identical 3.7v 860mAh li-ion cells, where one was controlled under a normal protocol, and another under BatteryOS. Both cells were kept at 100% charge in the chamber. Capacity was measured every week, with cells first being taken out to cool to room temperature.
