NB22 / NB24 / NB24k Battery Life Cycle Specifications

The NB22 / NB24 / NB24k series products leverage a high-quality lithium-ion based hot swappable battery. Below are the technical specifications of the battery life cycle:

Cycle Life: 300 Cycles to >=80% battery capacity

Test condition -
Charge: 0.2C to 4.35V (full charge)
Discharge: 0.2C to 2.75V (full drain)
80% or more of 1st cycle capacity at 0.2C discharge of Operation

A common question we receive is 300 cycles doesn’t sound like a lot! But this is the worst case discharge characteristics where a battery is fully discharged and then recharged. In most applications, partial discharging is used where a battery is discharged down to ~15% and recharged to 90% most of the time. This will tremendously improve the cycle life of a battery from 300 to several thousands.
