How to check compatibility
Verify your laptop model matches our compatible models list. Check your current battery’s part number against our reference list. Ensure physical dimensions match (typically 210mm × 50mm × 20mm).
When to replace
Replace your battery when it no longer holds sufficient charge for your needs, shows physical damage, or reaches 2-3 years of regular use. Most lithium-ion batteries degrade significantly after 500 charge cycles.

Avoid extreme temperatures (ideal range 15-25°C). Don’t leave laptop plugged in constantly. Perform partial discharges rather than full cycles. Store in cool, dry conditions if not used for extended periods.
