Battery Replacement
If your laptop dies the moment you unplug it, or the trackpad and case are bulging, the battery is worn out. We fit a quality replacement at our Marlboro shop and recycle the old one safely.

- It only runs with the charger connected
What we fit
Quality replacement batteries matched to your model, not the cheapest cell we can find. For phones and glued-in laptop batteries we use fresh adhesive and seals so the device closes up properly. Old batteries are recycled through a licensed handler.
Frequently asked questions
How much does a laptop battery replacement cost in Marlboro, NJ?
Battery replacement runs $40 to $370 depending on the device. A common Dell or HP laptop battery is at the low end, while MacBook, Surface and some ultrabook batteries are glued in and cost more in parts and labour. Give us the model for an exact price.
Is a swollen laptop battery dangerous?
Yes. A swollen battery is under pressure and can be a fire risk, and it also pushes on the trackpad, keyboard and screen. Stop using and charging the laptop, power it down, and bring it to our Marlboro shop soon for safe removal and replacement.
How long does a battery replacement take?
If we stock your battery it's often same day. Ordered batteries add a few business days. The fitting itself takes under an hour for most laptops and phones, and we test the charge cycle before returning the device.
How do I know if it's the battery or the charger?
If the laptop runs fine plugged in but drops instantly when unplugged, or the battery health shows high wear, it's the battery. If it won't charge at all, it may be the charger, port or board — the diagnostic tells us which before you buy a part.
