About this battery pack

A battery pack supplies power to a laptop or other portable device while it is disconnected from the mains. Inside it are rechargeable cells, most often lithium-ion or lithium-polymer in recent devices, together with a small circuit that tells the device how much charge remains and how healthy the pack is. All packs lose capacity as they age and go through charging cycles. A worn pack may run the device for only a short time, cause shutdowns while charge still shows, trigger a battery warning from the operating system, refuse to charge, or swell. A swollen pack should be taken out promptly and never charged again.

How to choose a replacement laptop battery

Is this the right part?

Find the part number on the battery label, normally on the side facing the underside of the device, where several numbers may appear. Before fitting, compare the shape, the connector and the voltage printed on the label with your old battery. The manufacturer's part number for this listing is 45N1735.

Not sure? Send us the number from the label, or your machine's serial number, and we will confirm the match before you order.
