Storing the LI-6800

The instrument can be stored for a few weeks without any special preparation. For short-term storage, park the chamber (not open, but not closed) to prevent the leaf gaskets from becoming deformed and remove the humidifier column to prevent the accumulation of humidity in the console.

For longer-term storage (a month or more), we recommend that you remove the batteries from the console and clean and dry the instrument with a soft damp (not dripping wet) cloth and mild detergent if needed. Clean the screen with common glass cleaners. Spray the cloth, not the glass.

The LI-6800 should always be stored in the case. The instrument storage temperature range is -45 to 50 ˚C, <85% relative humidity. The instrument will draw a small current when it is off. A fully charged battery will drain in about 7 months in an instrument that is off.

You can store the instrument with the desiccant and soda lime in the columns; however, you may need to replace the chemicals prior to using it again. Be sure the instrument stays below 50 °C during storage. We recommend the following before storing or shipping the instrument:

• Remove the CO₂ cylinder. Vent the gas to depressurize the cylinder, and then remove it. This prevents CO₂ adsorption to internal console components. This is especially important when storing the instrument in the closed case, which will trap the vented CO₂ gas.
• Remove the Nafion humidifier column and empty the water. This will prevent the accumulation of humidity in the console.
• Empty the Stuttgarter Masse humidifier column or remove it from the console. This will ensure that the valve manifold stays free of water in the event that the case becomes inverted.
• Remove any plant material from the leaf chamber.
• Park the chamber (do not close it) to prevent compressing the gaskets.

Battery storage

Batteries are manufactured by Inspired Energy®. Comprehensive storage and shipping information is available at www.inspired-energy.com/shipping.

Store the batteries with a 30 to 50% charge. Replenish the charge every 6 months of storage to avoid excessive discharge.

The battery storage conditions should be -20 to 60 °C, <80% relative humidity. However, it is best to store them below 21 °C in a cool, dry, well-ventilated facility free from corrosive gas or vapor. Storage at elevated temperatures (>45 °C) will degrade battery performance and reduce battery life. Storage at low temperatures may affect initial battery performance. Extended storage may require a calibration cycle or a few regular operating cycles to restore full accuracy to the fuel gauge.

If a battery exceeds a temperature or load threshold, a non-resettable fuse will open, rendering the battery non-functional.

If a battery become excessively discharged in storage, you can attempt to restore it by charging. The charger will supply a 3-minute wake-up charge in an attempt to activate the electronics. If this does not work, the battery should be replaced.

Battery removal

To remove the batteries, open the battery cover (see Figure 2‑4). Grasp the tab on the battery and pull.

Battery disposal

Lithium ion batteries must be disposed of safely. The batteries may cause environmental damage or damage to human health if they are disposed of improperly. Do not dispose of the batteries in unsorted municipal waste or an incinerator. Many localities have battery recycling facilities that will accept lithium ion batteries. Check your local regulations to determine how to dispose of the batteries.
