for it. Like all rechargeable batteries, the one in a laptop will gradually lose its capacity to hold a charge. Typically, the lithium-ion battery in a mobile PC will only retain 80 percent of its original capacity after the first year of use. You can find a wide selection of batteries for different laptop models at Staples®.

Pick the Right Laptop Battery for Your Mobile PC


The first step to choosing the right battery is knowing the PC’s model number or the product number of the battery installed in it. Do not just search for a replacement with only the brand and model as it’s quite common for a brand to offer different models of the same laptop. The exact model designation is usually an alphanumeric code printed on the device or on a label underneath it. Sometimes this information is enough to find the right computer battery. Users who need the exact part number for the battery can usually find it printed on the battery itself.

Factors to Consider When Getting a Replacement Laptop Battery


Users can choose between OEM and third-party replacement batteries for a laptop. New OEM ones may be rare since many manufacturers don’t make spare batteries for all of their products. Third-party laptop batteries are easier to find and typically more affordable. However, it’s important to find an exact match for the mobile computer. Start by searching with the laptop’s model number. When comparing different offers, make sure to read their product descriptions and confirm that the list of compatible notebooks includes your PC. Only choose a replacement battery from a reputable brand that provides a generous warranty. If the old battery is available, check its physical characteristics against the images provided in product listings. Make sure the shape and position of the connectors match the electrical contacts in the laptop’s battery compartment.

Can You Get a Higher Capacity Laptop Battery for Your Notebook?


Yes. Manufacturers quote the capacities of notebook batteries in milliamp-hour or mAh. The higher the mAh rating, the greater the amount of charge the battery can store. A battery with a higher capacity will keep a laptop running longer than one with a lower capacity. It is possible to find third-party batteries with higher capacities than the OEM battery that originally came with the device.

Do You Need to Match Voltage Rating When Ordering a Replacement Laptop Battery?


The most common voltages for laptop batteries are 7.2, 9.6, 10.8, 11.1, and 14.4 volts. Usually, batteries with more cells have higher nominal voltages. Users should try to find a replacement with the same voltage rating as the battery that came with the laptop. One’s with a higher capacity will most likely also have a higher voltage. However, PC power circuits can handle small deviations from recommended battery voltages. This means users can swap a 10.8-volt battery for a 9.6-volt unit but a 14.4-volt replacement may damage the laptop.

Should You Get a Replacement Laptop Battery Before You Need One?


No. A lithium-ion battery loses charge and capacity even when left unused. You need to charge it regularly to keep it in peak condition. Therefore, you should only get a replacement computer battery you intend to use immediately.
