blog about Guide to Extending Lithiumion Battery Life for Tektronix Devices

Have you ever experienced the frustration of a critical test being interrupted due to a sudden drop in battery power? High-performance Tektronix oscilloscopes, spectrum analyzers, and other precision instruments rely on dependable lithium-ion batteries to function optimally. However, like delicate orchids, these batteries require careful maintenance to prevent performance degradation, which can impact your efficiency and even lead to test failures.

To help you avoid such pitfalls, we present this detailed guide to maintaining Tektronix lithium-ion batteries. By following these best practices, you can optimize battery performance, extend lifespan, and ensure uninterrupted testing workflows.

Like all rechargeable batteries, lithium-ion cells are not perpetual motion machines—they require regular care and proper usage. Think of them as precision mechanisms that need lubrication and maintenance to perform at their best. The following guidelines serve as the golden rules for battery health, ensuring safety and longevity for your Tektronix equipment.

Batteries left unused for extended periods gradually lose their vitality. Whether installed in equipment or stored separately, lithium-ion batteries should not remain inactive for too long. If a battery has been idle for six months, check its charge status and recharge if necessary.

Lithium-ion batteries typically last 2-3 years or 300-500 charge cycles, whichever comes first. A charge cycle constitutes a full discharge followed by a full recharge. Even for batteries that haven't completed full cycles, the 2-3 year timeframe remains relevant.

All lithium-ion batteries experience irreversible capacity loss over time. As capacity diminishes, runtime decreases proportionally. While this natural aging process cannot be stopped, proper maintenance can slow its progression.

Even when unused or stored, lithium-ion batteries gradually lose charge. Regular status checks are essential to maintain optimal charge levels. Consult your Tektronix product manual for specific battery monitoring instructions.

Always use Tektronix-certified batteries to ensure peak performance and safety. Third-party batteries may compromise equipment functionality and pose potential hazards.

These specific maintenance practices will help maximize battery lifespan and reliability:

Record the operational duration of a new, fully-charged battery to serve as a performance benchmark. Note that runtime varies based on device configuration and applications.

Monitor battery charge levels routinely to identify potential issues early, such as slow charging or rapid discharge.

Batteries nearing their expected lifespan require closer monitoring as performance may deteriorate rapidly.

Consider replacement if:

• Runtime falls below 80% of original capacity
• Charging time increases significantly

Always follow manufacturer charging instructions. Key charging principles include:

• Avoid overcharging to prevent overheating
• Prevent deep discharge to protect internal structures
• Use only Tektronix-approved chargers

Correct storage significantly extends battery life:

• Store batteries at 50% charge
• Recharge to 50% every six months during storage
• Remove batteries from equipment when storing
• Maintain storage temperatures between 5°C and 20°C (41°F to 68°F)

Critical safety measures include:

• Never disassemble, crush, or puncture batteries
• Avoid short-circuiting battery contacts
• Keep batteries away from heat sources and water
• Store batteries out of children's reach
• Do not use damaged batteries

Always comply with local, national, and international regulations when transporting lithium-ion batteries. Note that damaged or recalled batteries may have specific transport restrictions.

Follow all applicable regulations when disposing of lithium-ion batteries. Contact certified rechargeable battery recycling services for proper disposal.
