• EliteBook 820 G3 laptop Battery Uses the highest quality graded and sorted 'A' Grade cells .
• Has resistance welded gold plated contacts for maximum performance.
• Provides excellent discharge characteristics.
• Uses high impact ABS and Polycarbonate plastic housings for ruggedness.
• Undergone comprehensive testing including high altitude performance, vibration, mechanical shock, thermal cycling, external short circuit and overcharge test simulations..

• Type: Lithium-ion and Lithium-polymer are standard material for laptop batteries. They have a good power-to-weight ratio and has no memory effect like some other battery materials.
• Voltage: The Voltage must be within 10% of your original Laptop Battery Voltage.
• i.e. 11.1V is ok for your original 10.8V Battery; 14.4V is ok for your original 14.8V Battery
• Capacity: Laptop batteries will typically list their capacities in milliamp hours (mAh) or Wattage (Wh). A higher mAh or Wh rating means the battery will take longer to drain, giving your laptop a longer runtime per charge.
• Cell: Extended batteries (i.e. 9 cell or 12 cell) are usually has extra run time of laptop in between charges, usually bigger in size and weigh more than a standard laptop battery (i.e. 6 cell).
