When to Replace Your Laptop Battery
Replace when: battery health drops below 60%, the laptop shuts down unexpectedly, or runtime is under 2 hours for a machine rated for 8+. Most laptop batteries last 2-4 years or 300-500 charge cycles.
Finding the Right Battery
Use your laptop model number to search for replacement batteries. OEM batteries from the manufacturer cost more but guarantee compatibility. Third-party batteries from reputable brands (Green Cell, DTK) cost 30-50% less and work well in most cases.
Safety Warning
Never buy extremely cheap, unbranded batteries — they may lack safety certifications and could be fire hazards. Look for batteries with UL, CE, or FCC certifications. Dispose of old batteries at designated recycling points.
