Laptop batteries

When a laptop only lasts minutes off the charger or shuts down without warning, a replacement battery is usually far cheaper than a new computer. This category gathers batteries for laptops from different manufacturers and series. Compatibility comes first: match your laptop model and the part number printed on the old battery, and check the voltage. Capacity in mAh or Wh indicates how long the machine will run unplugged - the higher the figure, the longer the working time. Before ordering, make sure the new battery matches the original in shape and connector.
