Replacement battery for Dell laptops

This 3-cell lithium-ion unit delivers 11.4 volts, 42 watt-hours and 3500 milliampere-hours in a black housing. It is built as a direct swap for compatible Dell notebooks that originally shipped with the same cell count and voltage. The pack targets owners who need to restore original run-time on an aging machine. Buyers seeking higher capacity or a different form factor should look elsewhere.

Verify part number and voltage before ordering

Confirm that the existing battery carries the 542WP or JTG7N code and shows 11.4 V on its label. Mismatched voltage or connector layout will prevent installation and could damage the notebook. The replacement uses the same three-cell lithium-ion chemistry, so no firmware update is required. Systems requiring a different cell count or a proprietary connector are not supported.
