For the Battery
Lithium battery packs may get hot, explode, or ignite and cause serious injury if
exposed to abuse conditions. Be sure to follow these safety warnings:
The AC/DC adapter is for indoor use only.
Never use a modified or damaged charger. Use the original AC–DC
adapter ONLY.
The AC/DC adapter is designed for use in Installation Category II and
Pollution Degree 2 per IEC 61010-1.
If charging batteries externally, use the optional external charger available
from Keysight, or another SMBus charger of level II or higher.
Never use a non–SMBus charger because the battery issues commands
over the SMBus to the charger to control the charge rate and voltage.
Never use a modified or damaged charger.
