Laptop battery replacement costs between $50 and $200 for the part alone, depending on your laptop model and battery type

The actual battery component typically runs $50 to $150 if you buy it yourself and install it. If you have a technician do the work, add $50 to $100 in labor, bringing the total to $100 to $250. Some newer laptops have batteries soldered directly to the motherboard, which means replacement costs jump to $200 to $400 because the entire logic board may need replacement.

The price depends on three things: whether your laptop uses a removable or built-in battery, the wattage and chemistry of the battery your model needs, and whether you do the work yourself or pay someone else. A five-year-old Dell with a removable battery costs far less to fix than a current MacBook Air with a glued-down battery.

Key Takeaways

  • Removable batteries cost $50 to $100 and take five minutes to swap yourself; built-in batteries cost $100 to $150 plus $50 to $100 in labor if a technician installs them.
  • Apple MacBooks and newer ultrabooks often have batteries soldered to the motherboard, which means you pay $200 to $400 for the entire repair because the logic board must be replaced.
  • Buying a battery from the laptop manufacturer costs more than a third-party equivalent, but third-party batteries sometimes have shorter lifespans or lower capacity.
  • If your laptop is still under warranty, battery replacement may be covered at no cost if the battery is defective rather than worn out from normal use.

Removable batteries versus built-in batteries

Laptops made before 2015 almost always have removable batteries — a plastic cartridge that slides or clicks out of the bottom or side of the case. These cost $50 to $100 to replace and require no tools or technical skill. You order the part online, slide the old one out, slide the new one in, and you are done. This is the cheapest and fastest route.

Most laptops made after 2015, especially thin models, have built-in batteries glued or soldered directly inside the case. Removing one requires disassembling the laptop, which takes 30 minutes to an hour and risks damaging the screen, keyboard, or motherboard if you slip. The battery itself costs $100 to $150, but you will almost certainly need a technician to install it, adding $50 to $100 in labor. Total cost: $150 to $250.

A few high-end laptops, particularly MacBooks and some gaming machines, have batteries soldered directly to the motherboard. In these cases, the entire logic board must be replaced to get a new battery. This costs $200 to $400 and is often not worth doing on an older machine.

Where to buy and what you will pay

The manufacturer's website (Dell, HP, Lenovo, Apple, Asus) sells official batteries and usually charges the most — typically $120 to $180 for a built-in battery. These are may provide to work and often come with a one-year warranty.

Amazon, Newegg, and other electronics retailers stock third-party batteries from brands like Anker, Powerex, and Juiced for $60 to $120. These are cheaper and often arrive faster, but quality varies. Read the reviews carefully — a battery with 2.5 stars instead of 4.5 stars may fail after six months instead of three years.

Local repair shops (Best Buy's Geek Squad, independent computer repair stores, phone repair chains) will sell you a battery and install it for a combined $150 to $250. They typically stock common models and can often do the work the same day. Call ahead to confirm they have your specific battery in stock.

Labor costs if you use a technician

If your laptop has a removable battery, you do not need a technician — the cost is just the battery itself, $50 to $100.

For a built-in battery, a technician charges $50 to $100 in labor depending on how difficult your laptop is to open. A thin ultrabook takes longer than a thick gaming laptop, so expect the higher end of that range for MacBooks and Dell XPS models. Some shops charge a flat rate ($75 to $100) while others charge hourly ($60 to $100 per hour). Ask which before you drop off your laptop.

If the battery is soldered to the motherboard, the technician will not be replacing just the battery — they will be replacing the entire logic board. This is a $200 to $400 job and usually takes a week or more because the board must be ordered and the laptop must be fully disassembled and reassembled.

Manufacturer warranty and defect coverage

If your laptop is still under the manufacturer's warranty and the battery is defective (not just worn out), the replacement is usually free. A defective battery is one that fails to hold a charge after only a few months of normal use, or one that swells and damages the case. A battery that lasts two years and then stops holding a charge is considered worn out and is not covered.

Contact the manufacturer's support line with your laptop's serial number. They will ask you to run a battery diagnostic test (built into Windows and macOS) to confirm the battery is failing. If it is, they will either mail you a replacement battery or direct you to an authorized repair center that will install it for free.

AppleCare+ extends coverage to accidental damage and battery degradation for three years, so if you have AppleCare+ on a MacBook, battery replacement is free during that period. Standard Apple warranty covers only defects, not normal wear.

Signs your battery needs replacement soon

Your battery is nearing the end of its life if your laptop shuts down at 20 percent charge, takes longer than three hours to charge fully, or drains completely in under an hour of light use. These are normal signs of aging — lithium batteries degrade over time and cannot be repaired, only replaced.

If your battery is swollen (the case is visibly bulging or the trackpad feels raised), stop using the laptop when ready and replace the battery as soon as possible. A swollen battery can catch fire. Do not try to remove it yourself — take it to a repair shop or the manufacturer.

If your laptop is three to five years old and the battery no longer lasts through a workday, replacement is usually worth the cost. If your laptop is seven years or older, consider whether the total repair cost (battery plus any other aging parts) makes sense compared to buying a used replacement laptop.

Frequently Asked Questions

Can I replace a MacBook battery myself?

Not easily. MacBook batteries are glued down and soldered to the logic board, so removal requires disassembling the entire laptop and risks damaging the screen. Apple charges $129 to $199 for the battery plus $99 to $199 in labor. Independent repair shops may charge less ($150 to $250 total), but the work is still complex.

How long does a laptop battery last?

Most laptop batteries last two to four years with normal daily use. A battery used eight hours a day will degrade faster than one used three hours a day. After 500 to 1,000 charge cycles, most lithium batteries hold only 80 percent of their original capacity.

Is it cheaper to buy a used battery?

Used batteries are rarely worth buying. A used battery is already partially degraded, so it will not last long. New third-party batteries cost only $60 to $100, so the savings are minimal and the risk is high.

What if my laptop model is discontinued?

Third-party sellers often stock batteries for older models for years after the laptop stops being made. Search your exact model number plus "battery" on Amazon or eBay. If nothing comes up, a local repair shop may be able to order one or suggest a compatible alternative battery from a different brand.

Does replacing the battery void my warranty?

If you replace the battery yourself or use a third-party technician, it does not void the warranty on other parts of the laptop. However, if something goes wrong during the replacement (like a cracked screen), that damage is not covered. If you are still under warranty and the battery is defective, always contact the manufacturer first.
