Do not leave a battery unused for an extended period of time, either in the product or in storage. When a battery has been unused for six months, check the charge status, and charge or dispose of the battery as appropriate. See Charging the battery and Battery recycling.

The typical estimated life of a lithium-ion battery is about two to three years, or 300 to 500 charge cycles, whichever occurs first.

A rechargeable lithium-ion battery has a limited life and will gradually lose its capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.

A lithium-ion battery continues to slowly discharge (self-discharge) when not in use or while in storage. You need to routinely check the charge status of the battery.

Only use the battery in approved Tektronix instruments.

• Observe and note the run time that a new fully-charged battery provides for powering your product. You can use this new battery run time as a basis to compare run times for older batteries. The run time of your battery will vary depending on the product's configuration and the applications that you run.
• The battery gives the best performance when operated at normal room temperature, 20°C ±5°C (68°F ±9°F).
• Routinely check the charge status of the battery.
• Carefully monitor a battery that is approaching the end of its estimated life.
• Consider replacing the battery with a new one if the battery run time drops below about 80% of the original run time, or the battery charge time increases significantly.
• Follow the storage requirements if you store or do not use a battery for an extended period. If you do not follow the storage requirements, and the battery will not power the instrument when installed, consider the battery to be damaged. Do not connect power to the instrument during this time. Remove the battery from the instrument. Do not attempt to recharge or reuse the battery. Replace it with a new battery.

The battery charges automatically when installed in an approved Tektronix instrument that is connected to an external power supply. You can also charge the battery with the Tektronix external battery charger (TEKCHG-XX). Remove the battery from the charger when charging is complete.

A lithium-ion battery will self-discharge during non-use. To achieve the longest operating time, charge your battery before use. If you plan to store batteries, read the instructions in the Battery storage section of this document.

CAUTION:To avoid damage to the battery, use only the Tektronix external battery charger or an approved instrument to charge the battery. Do not connect any other voltage source to the battery.

For optimum performance, charge the battery completely before using it for the first time or after prolonged storage.

To discharge the battery completely, continue to run the instrument on the battery until automatic shutdown occurs. After the instrument shuts down, either recharge the battery promptly or remove it from the instrument until you are ready to recharge the battery.

Note:To prolong the life of the battery and to prevent shutdown, do not operate or charge the battery at high temperatures. For best results, allow the battery to cool to room temperature before using or charging the battery. Do not leave a battery discharged for extended periods. See the Storing batteries section for information on how to properly store a battery.

• Do not disassemble, crush, drop, or puncture the battery.
• Do not short the external contacts on the battery.
• Do not expose the battery to fire or water.
• Do not expose the battery to temperatures above +60°C (+140°F).
• Seek medical advice if a battery or part of it has been swallowed.
• Do not put batteries near heat or fire. Do not put in sunlight.
• Keep the battery clean and dry. Clean dirty connectors with a dry, clean cloth.
• Batteries contain hazardous chemicals that can cause burns or explode. If exposure to chemicals occurs, clean with soap and water and get medical aid. Repair the product before use if the battery leaks.
• Do not attempt to open, modify, reform or repair a battery that appears to be malfunctioning, or which has been physically damaged.
• Keep the battery away from children and animals.
• Avoid exposing the battery to excessive shock or vibration.
• Do not use a damaged battery or charger.
• If a battery has leaking fluids, do not touch any fluids. Dispose of a leaking battery. See the Battery recycling section for information on disposal and recycling.
• In case of eye contact with fluid, do not rub eyes. Immediately flush eyes thoroughly with water for at least 15 minutes, lifting upper and lower lids, until no evidence of the fluid remains. Seek medical attention.

• Store batteries in a low-humidity environment free of corrosive gases. Storing batteries in high-humidity environments, or outside the temperature range, can cause oxidation on the metallic parts, increased leakage, significant aging and premature failure.
• Do not store batteries near heat or fire. Do not store in the sunlight.
• Do not keep batteries in a place where the terminals can be shorted by metal objects (for example, coins, paper clips, or pens).
• Do not remove a battery from its original packaging until required for use.
• When possible remove the battery from the equipment when not in use.
• Charge the battery to approximately 50% of capacity at least once every six months.
• Remove the battery and store it separately from the instrument. Refer to the documentation for your instrument for instructions on removing and installing the battery.
• For optimal battery life, store the battery at temperatures between +5°C and +25°C (+41°F and +77°F). Higher temperatures reduce the battery storage life.

Replace the lithium-ion battery only with a TEKBAT-XX battery.
