Do’s and Don’ts for Lithium Batteries: Best Practices for Safety, Performance, and Longer Battery Life

Lithium batteries power critical devices across industries, from handheld equipment and warehouse scanners to robotics, medical devices, and mobile electronics. Proper battery maintenance is essential for maximizing battery performance, battery lifespan, and workplace safety.

When lithium battery packs are stored, charged, or used incorrectly, they can lose capacity, fail prematurely, or create safety risks. By following proven battery management best practices, businesses can reduce downtime, improve reliability, and protect their operations.

At Apex Mobile Power (AMP), we design and support custom lithium battery systems built for demanding applications. Below are key do’s and don’ts for maintaining lithium-based batteries.

Why Lithium Battery Maintenance Matters

A healthy battery delivers dependable power when your device or operation needs it most. Poor battery health can lead to:

• Reduced runtime
• Lower charging efficiency
• Premature battery replacement
• Equipment downtime
• Increased safety risks
• Higher long-term operating costs

Whether you use batteries in logistics, healthcare, public safety, or industrial environments, a proactive battery maintenance strategy matters.

Do’s and Don’ts for Lithium Batteries

1. Do Store Lithium Batteries Correctly

Proper battery storage is one of the most important factors in preserving lithium battery health.

Best Practices for Storage:

• Store batteries at approximately 40–50% state of charge
• Keep batteries in a cool, dry environment
• Avoid long-term storage in high temperatures
• Inspect stored batteries regularly

Why It Matters:

Storing lithium batteries fully charged can accelerate capacity loss over time. Heat speeds up battery degradation, reducing the battery’s usable life.

Don’t:

• Store batteries at 100% charge for extended periods
• Leave batteries in hot vehicles or non-climate-controlled spaces
• Ignore long-term storage conditions

2. Do Monitor Battery State of Health

Battery State of Health (SOH) reflects the battery’s ability to perform compared to when it was new. Many factors influence SOH, including:

• Storage conditions
• Charging habits
• Usage cycles
• Temperature exposure
• Battery design quality
• Manufacturing consistency

‍

Best Practice:

Track runtime, charging behavior, and performance changes over time. Declining performance may indicate aging batteries that need replacement.

3. Do Use the Right Charging System

Charging systems should be matched to the battery’s specifications and managed by proper electronics such as a Battery Management System (BMS).

A Quality BMS Helps Protect Against:

• Overcharging    
• Over-discharging    
• Overcurrent events
• Temperature extremes
• Cell imbalance

Don’t:

• Use incompatible chargers
• Ignore overheating during charging
• Continue charging batteries showing signs of damage

A properly engineered charging system improves battery safety and extends service life.

4. Do Protect Batteries from Extreme Temperatures

Temperature has a major effect on lithium battery performance and safety.

High Temperatures Can Cause:

• Faster degradation
• Capacity loss
• Reduced cycle life
• Thermal instability
• Safety failures

Low Temperatures Can Cause:

• Temporary power loss
• Reduced available runtime
• Lower discharge performance

Best Practice:

Use batteries only within approved operating temperature ranges and rely on BMS protections whenever possible.

5. Don’t Deep Discharge Lithium Batteries Repeatedly

Running batteries to extremely low voltage levels too often can shorten battery life and stress internal components.

Best Practice:

Recharge batteries before they remain deeply discharged for extended periods.

A properly designed BMS should help prevent unsafe discharge levels.

6. Do Remove End-of-Life Batteries from Service

All rechargeable batteries eventually reach End of Life (EOL). Continuing to use aging batteries can create performance and safety concerns.

Common EOL Indicators:

• Noticeably shorter runtime
• Fast charging with little runtime gained
• Swelling or bulging
• Leaking electrolyte
• Strange odor
• Corrosion or crystal buildup
• Visible physical damage
• Excessive heat during use or charging

Typical Replacement Benchmarks:

• Around 400–500 charge cycles (varies by chemistry and usage)
• Battery capacity below 80% of original rating
• Manufacturer date or service-life guideline reached

7. Do Recycle Lithium Batteries Properly

Used lithium batteries should never be discarded carelessly or left sitting in storage areas indefinitely.

Why Recycling Matters:

• Reduces fire risk from damaged batteries
• Supports environmental sustainability
• Keeps hazardous materials out of landfills
• Recovers valuable materials for reuse

Best Practice:

Implement a battery recycling program and train employees on safe battery disposal procedures.

Build a Better Battery Replacement Program

For businesses managing fleets of battery-powered devices, scheduled battery replacement programs help improve uptime and safety.

Consider:

• Date-code tracking
• Color-coded replacement systems
• Routine battery inspections
• Performance testing
• Planned lifecycle replacement schedules

A proactive battery strategy prevents unexpected failures and supports productivity.
