Laptop Battery Replacement Cost in the UK
What a laptop battery replacement typically costs in the UK, signs your battery is worn out, and the difference between internal and removable designs.
A laptop that dies after forty minutes or only works plugged in has probably got a worn battery. Replacement is usually cheaper than people fear, and it can add years to a machine that is otherwise doing fine.
Typical costs
Prices vary by model, region and whether the battery is easy to reach:
- Removable battery: the part often costs around £25 to £70, and you can fit it yourself in a minute.
- Internal battery, easy access: part around £30 to £90, with labour typically around £30 to £60.
- Internal battery, glued or sealed design: part around £50 to £130, with labour that can reach £60 to £100 because of the extra time and care required.
Total bills of roughly £60 to £180 are typical. Genuine manufacturer parts cost more than compatible ones, and cheap unbranded batteries are not worth the saving, as quality varies and fire risk is a real concern with lithium cells.
How to tell if the battery is the problem
Not every short runtime is caused by wear. Check these before you buy:
- Look at battery health. Your operating system can usually generate a battery report or show health and cycle count in system information.
- Check what is draining it. Heavy background apps, bright screens and a hot, dusty machine cut life.
- Try a different charger. A faulty or underpowered charger can make a healthy battery look poorly.
- Look for physical signs. A bulging battery that lifts the trackpad or makes the case bow is dangerous. Stop using it and unplug it straight away.
If the laptop only works on mains power, shuts off at a high percentage or shows "plugged in, not charging", the battery is a likely suspect, though the charging circuit can also be to blame.
Safety matters
Swollen lithium batteries can vent or catch fire. Do not charge a swollen battery, do not puncture it and keep it away from heat. Old batteries should never go in household bins. Take them to a recycling point or retailer take-back scheme. Our guide on disposing of old computers and phones safely covers what to do.
Is it worth replacing?
A battery is one of the best-value repairs when the rest of the laptop is healthy. It is less sensible if:
- The machine is very slow or no longer receives security updates.
- The screen, hinges or keyboard are also failing.
- The repair price approaches half the cost of a similar replacement.
Our article on whether an old laptop is worth repairing has more on weighing these up.
Getting more life from a new battery
- Avoid leaving the laptop at 100 percent on charge and hot for weeks. If your system offers a charge limit setting, use it.
- Keep vents clear. Heat is the battery's enemy; see fixing laptop overheating and loud fans.
- Lower screen brightness and close unused apps when on the move.
- Use the right charger with the correct wattage.
Hiring someone
You can find help on Compito by searching your postcode, comparing ID-verified local providers and sending a request with your laptop model. You get an offer you can accept and pay for online, and can message the provider to confirm the type of battery being fitted. See tech support services.
A worked example
A five-year-old ultrabook with a sealed battery gives about 50 minutes off the charger. A health check shows significant capacity loss. A quote of about £90 to £150 including a compatible battery and fitting is quite typical. The same machine has an SSD, runs current updates and is otherwise quick, so the repair extends its life by a few years for a fraction of the cost of a new laptop. Had the same machine been slow, cracked and on an unsupported operating system, the same money would have been better directed towards a replacement.
Choosing the replacement part
- Manufacturer parts cost more but are matched to the machine, and charge control tends to behave best.
- Reputable compatible parts can be a fair compromise if the supplier is established and the part is labelled with capacity and cell details.
- Very cheap listings with inflated capacity claims are a bad bet. Check reviews, and be wary of anything wildly cheaper than the rest.
Ask whoever does the work to tell you which kind they are fitting and whether the part has a warranty period from the supplier.
What to ask the technician
- Is the battery the confirmed fault, or are you guessing?
- Which part will be fitted, and what capacity does it have?
- What does the price include: part, labour, disposal of the old battery?
- How long will it take, and will my data be touched?
- What happens if the new battery does not fix the symptoms?
Back up first
Opening a laptop carries a small risk, and fitting a part is rarely the moment you want to discover a missing backup. Copy your important files before any repair. See how to back up your computer.
Doing it yourself
On removable or simple screw-down designs, a careful owner can do it with a small screwdriver set and the manufacturer's guidance. On glued designs, or where prising is involved, a mistake risks puncturing a cell. If you are unsure, pay for the labour; it is a small share of the bill.
Frequently asked questions
How long should a laptop battery last?
Most last a few years of regular use. Capacity drops gradually, and many people notice a real decline after two to four years depending on use and heat.
Can I use the laptop without a battery?
Many laptops will run on mains power alone with the battery removed, though some will not or will limit performance. Check the manual, and note that a power cut will then shut the machine down instantly.
Is a swollen battery an emergency?
It is a safety risk. Switch off, unplug, avoid charging and arrange proper replacement and disposal promptly.
