Verify your laptop model matches our compatibility list above. Check your current battery part number (usually printed on the battery) or locate your laptop model number on the bottom casing or in system information.
When to replace
Replace your battery when you notice significant performance decline (less than 2 hours runtime), swelling, or if it’s been 2-3 years of regular use. For rugged laptops used in demanding conditions, consider annual battery health checks.

Usage & care tips
For optimal battery life: avoid complete discharges, store between 20-80% charge when not in use, keep between 15-25°C operating temperature, and perform monthly full charge cycles. Use only authorised Dell chargers.
