Lithium-Ion Battery FAQs

❓ FAQ 1: Are Lithium-Ion Batteries Safe?

• Li-ion batteries are generally safe but can overheat, swell, or catch fire if damaged, overcharged, or exposed to extreme temperatures.

Safety tips:

• Use only manufacturer-approved chargers.
• Avoid puncturing or crushing the battery.
• Store in a cool, dry place (ideally between **20°C–25°C / 68°F–77°F**).

❓ FAQ #2: How Long Do Lithium-Ion Batteries Last?

• Capacity gradually degrades over time—after 500 full cycles, most Li-ion batteries retain ~80% of their original capacity.

Extend lifespan by:

• Avoiding full 0%→100% charges (keep between 20%–80%).
• Reducing exposure to high heat (e.g., don’t leave phones in hot cars).

❓ FAQ #3: Can I Leave My Li-Ion Battery Plugged In Overnight?

❓ FAQ #4: Why Do Lithium-Ion Batteries Swell?

• Swelling indicates battery failure—stop using it immediately!

• Physical damage (e.g., drops).
• Frequent deep discharges (draining to 0%).
• Poor-quality chargers.

❓ FAQ #5: How Should I Store Lithium-Ion Batteries?

• Never store fully charged or fully drained—both degrade the battery.
• For long-term storage, check and recharge to 50% every 6 months.
