Care and Maintenance
Battery
LabQuest Stream uses a high-quality lithium-ion battery. This is the same
chemistry used in premium laptop and cell phone batteries, and you can expect
similar performance.
Use the supplied AC adapter, USB cable, or optional Charging Station
(order code LQ2-CRG) to charge the battery. The battery takes 8 to 10 hours to
fully charge. The battery cannot be overcharged, and it can be safely recharged
after a partial discharge. It is safe to leave the battery charging indefinitely, and
there is no need to fully discharge the battery before needing to charge it.
The discharge time for a fully charged battery will depend on the sensors used. In
most cases, you can obtain 24 or more hours of use before recharging. We
recommend charging LabQuest Stream overnight to start the next day with a full
charge.
