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.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
