Why Lithium Batteries Fail

Causes:

• Natural Aging — Capacity drops over time
• High Charge Cycles — Hundreds of cycles = reduced performance
• Heat Exposure — Speeds up chemical breakdown
• Overcharge / Deep Discharge — Stresses and damages cells
• Physical Damage — Drops, vibration, internal shorts
• Low‑Quality Aftermarket Cells — Faster degradation

Common Warning Signs

• Rapid Discharge — Battery drains faster than normal
• Swelling / Bulging — Gas buildup; dangerous
• Overheating — Hot during use or charging
• Slow or Stuck Charging — Won’t reach 100%
• Unexpected Shutdowns — Device dies with charge remaining
• Cell Imbalance — Uneven aging in multi‑cell packs

🔍 SECTION 3 — How to Spot Battery Failure Early

Visual Checks:

• Swelling
• Cracks or leaks
• Warped casing

Performance Checks:

• Shorter runtime
• Sudden percentage drops
• Shutdowns under load

Charging Behavior:

• Stuck at 80–90%
• Overheating while charging
• Charger disconnects

SECTION 4 — What You Can Do

Good Habits:

• Avoid 0–100% cycles
• Keep battery cool
• Use the correct charger
• Store at 40–60%

Avoid:

• Cheap aftermarket batteries
• Overcharging
• Leaving battery in hot environments
