Macbook Battery Replacement in Horsham, Sussex, the South East, London & beyond.

There will come a point in time where your Macbook’s battery is no longer functioning as it was designed often with the ‘service now’ warning. In many cases when the battery has degraded to such a state the battery cells will start swelling as they fill with gases. In some cases it can be visibly seen with a bulging base, or even a bulging track pad from the pressure. Often with scenarios like this the track pad may be erratic or even non responsive.

The process of removing the battery from all macbook Pro’s mid 2012 onwards is quite tricky as they are glued in firmly. If the correct method and tools are not used correctly the battery can be pierced leading to it catching fire.
The correct process utilises solvent to help break the glue down, then a wire and pry tools are carefully manipulated to safely remove the battery.

Once the old battery is out it is disposed of into a fire proof drum where once full it’s then collected.

The spent volatile batteries are sent off to be broken down for the Li-ion to be reused rather then go off to land fill which is terrible for the environment. Many other repair shops will replace the entire top case at great cost to yourself, as well as the environment.

With the battery removed the top case in now cleaned up like new and the new genuine replacement battery is now bonded into place.

The cost of battery replacement for your Macbook starts at just £120 up to £240 for 2020 model macbooks.

Macbook battery calibration - Important!

Batteries Are Shipped Up To 70% Pre-Charged…

It’s absolutely essential to calibrate the power management system after installing any new battery. The power calibration process syncs the computer’s power management system with the battery which allows:

Your new battery to achieve its fullest charge capacity.
Your new battery to reach its full lifespan.
The system to accurately display the battery level.

Tip: You may have more life in your stock battery than you think!
You can also use this power system recalibration guide with the stock battery that came with your Apple laptop.

Calibrating The Power Management System Is Easy To Do. After The New Battery Is Installed...

Step 1 – Verify Installation

To ensure the new battery is properly installed, turn the computer on without the power adapter connected.
If the computer starts up normally, the battery is properly installed and you can proceed to Step 2.
If the computer does not start up, please double-check the battery install instructions to ensure it’s correctly installed.

Step 2 – Charge The Battery To 100%

Shut down the computer and then connect the power adapter.
Keep the computer plugged in until the light on the power connector turns green indicating a 100% charge.

Step 3 – Charge Two More Hours

After the battery is 100% charged, keep the power adapter plugged into the computer for an additional 2+ hours.
The computer can be powered up and used during this time.

Step 4 – Temporarily Change the Energy Saver Settings

If the computer is off, you’ll need to turn it on.
In OS X System Preferences click on the Energy Saver preferences.
In the Energy Saver / Battery preferences:
- Set the “Turn display off after:” slider to “Never”
  Various Mac models may have two sliders for “computer sleep” and “display sleep”. If you have two sliders, simply slide both to the right to set them to “Never”
- UNCHECK “Put hard disks to sleep when possible”
- UNCHECK “Slightly dim the display while on battery power”
Note: The location / existence of certain settings may shift or vary depending on your computer model or OS version.

In the Energy Saver / Power Adapter preferences:

Set the “Turn display off after:” slider to “Never”
Various Mac models may have two sliders for “computer sleep” and “display sleep”. If you have two sliders, simply slide both to the right to set them to “Never”
CHECK “Prevent computer from sleeping automatically when the display is off”
Note: this setting may or may not be available depending on your model or OS version.
UNCHECK “Put hard disks to sleep when possible”

Note: The location / existence of certain settings may shift or vary depending on your computer model or OS version.

Step 5 – Unplug And Drain The Battery

Unplug the power adapter.
Leave the computer on until it automatically shuts down.
You can use the computer during this step, but don’t put the computer through heavy use to deplete the battery faster. Steady, even usage is better for power system calibration.

Step 6 – Leave It Off And Unplugged

After the computer has automatically shut down, leave it shut down for at least 5 hours or overnight. This will ensure the battery is completely drained of energy.

Step 7 – Charge To 100% Again

Plug the computer back in until the battery is 100% charged.
While plugged in, the computer can be used.
This is also a good time to go back and select your desired Energy Saver preferences.

AND THAT’S IT.

After this essential calibration, the new battery will be able to achieve its fullest charge and reach its full lifespan, and the system will display an accurate battery level. You can also reuse these steps to recalibrate the power management system every few months if desired.
