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.
The long-term life of the battery will vary, but you can expect about 500 full charge/discharge cycles before the battery will need to be replaced. In this count, a charge from half charged to a full charge counts as half of a charge cycle. In typical school use, the battery can last three years or more. Exposure to temperatures over 35°C (95°F) will significantly reduce battery life.
As a battery reaches the end of its functional life, the discharge time for a fully charged battery will become shorter. Eventually the discharge time will be too short for your application, and you will want to replace the battery. Rechargeable batteries are considered a consumable, and as such, are warranted for one year. A replacement battery can be ordered from our website (order code LQ2‑BAT).

Use only the supplied battery for this device. Do not puncture or expose the battery to excessive heat or flame.
Safe operating temperatures for LabQuest Stream are from 0°C to 45°C (32°F to 113°F). Storage temperatures are –30°C to 60°C (–22°F to 140°F). Exposures to low or high extreme temperatures will temporarily reduce the discharge time for a fully charged battery. Exposure to temperatures over 35°C (95°F) will significantly reduce long-term battery life.
Avoid rapid temperature changes as condensation may form inside the device. Do not leave it in a car, as temperatures can exceed the maximum storage range.
LabQuest Stream is not water resistant and should never be immersed in water. If water gets in the device, immediately remove the USB cable and turn the unit off by holding down the power button for at least 3 seconds. Disconnect all sensors and cables and remove the battery. Allow the unit to dry thoroughly before restarting it. Do not attempt to dry it using an external heat source.
Do not store LabQuest Stream in a chemical closet or in areas of concentrated chemical gases.
Safe storage temperatures are –30°C to 60°C (–22°F to 140°F). Exposing the battery to temperatures above 35°C (95°F) will reduce its lifespan. If possible, store LabQuest Stream in an area that is not exposed to temperature extremes.
To store LabQuest Stream for extended periods of time, turn the unit off and remove the battery. Over several months, the battery will discharge but will not be damaged. After such storage, charge LabQuest Stream (a full charge can take 10 hours), and the unit will be ready for use.
