Signs your battery needs replacing

The laptop dies the moment you unplug it
A full charge lasts a fraction of what it used to
Windows/macOS warns "replace your battery"
The battery or trackpad area is bulging
It won’t charge past a certain percentage
The laptop shuts off suddenly at "50%"

The straight answer first

A swollen battery is not just a performance problem — it’s a safety issue. If your trackpad is lifting or the case is bulging, stop using the laptop and bring it in; a swelling lithium battery should be replaced promptly and disposed of properly.

A fresh battery is one of the cheapest ways to get years more life out of a laptop you otherwise like. If yours is worth keeping, this is usually money well spent — and we’ll tell you if it isn’t.

How it works

Simple, honest, and you approve the price before any work begins.

Confirm it’s the battery

We check the battery’s health and charge circuit to be sure the battery — not the charger or port — is the problem.

Fit the correct cell

We install a quality replacement battery matched to your exact model, so capacity and safety are right.

Calibrate & test

We calibrate the new battery, verify charging and runtime, and safely recycle the old one.

Frequently asked questions

How much is a laptop battery replacement?
Labour starts at $49.99, plus the battery itself, which depends on your make and model. We source the correct cell and confirm the total before fitting it.
My laptop only works when plugged in — is that the battery?
Usually yes, but not always — it can also be the charger or charging port. We test all three so you only pay to fix what’s actually wrong.
Is a swollen battery dangerous?
It can be. A swelling battery should be replaced promptly and recycled safely. Stop using the laptop, avoid charging it, and bring it in — we’ll handle it properly.
How long does it take?
Once we have the correct battery, replacement is quick — often same day. Sourcing a battery for an uncommon model can add a day or two, and we’ll tell you upfront.
Will a new battery restore full runtime?
A quality replacement restores runtime close to when the laptop was new, assuming the rest of the machine is healthy. We calibrate it and confirm the results before handover.
