Many of our replacement GPS battery packs come with all of the tools you’d need to replace the battery yourself at home.

Replace your battery, not your GPS device

Long journeys on unfamiliar roads by car, bike or motorbike by motorbike require a reliable Sat Nav - and one with a long life battery is crucial. If your original GPS battery no longer holds its charge, don’t throw away your device - simply replace its battery.

By changing your Sat Nav’s battery pack instead of buying a new device, you not only save money by giving your old device a second life, you’re also helping the environment by reducing waste.

The modern replacement GPS and Navi batteries from subtel®’s brand, CELLONIC®, are also often higher-capacity and longer life than even the original batteries that came with your device - for reliable power and fewer charging breaks.

It’s often very simple to replace the battery of your Satellite Navigation device yourself - all you need is a compatible replacement battery pack, a few good tools and an online tutorial or YouTube video.

Certified safety and proven quality

All subtel® and CELLONIC® batteries use the highest-quality cells: E & ROHS certified, Grade A battery cells with short-circuit, overheating and overvoltage protection that have been tested and certified for optimum capacity, reliability and safety – all before installation.

3-year manufacturer’s warranty

Our Fast Charging, longlife GPS battery replacements stand for certified safety and high-quality standards. Because of this, we offer a 36-month guarantee on all of our batteries.

How do I choose the right replacement battery for my GPS?

There are many battery brands and types on the market. But, how do you find the correct replacement battery for your Sat Nav device?

Compatibility. You want to find a battery that 100% fits your device. Preferably one that was designed specifically as a replacement battery for your device. To find out if a battery is a match for your device, look at the model/serial number on your battery or device and find a replacement that is compatible with it.

All of the replacement GPS batteries for sale on our subtel® webshop are listed with a compatibilities list. Check this list to ensure you find the 100% compatible battery for your device before you buy it.

Correct voltage. Ensure whatever replacement battery you purchase has the same voltage as your original battery. Small differences are acceptable - deviations of 0.1V-0.2V, for example - but anything above or below that could potentially damage your Sat Nav.

Capacity. The capacity of a battery, indicated in mAh (milliampere hours) or Ah (ampere hours), represents how much charge that battery can store and provide. Essentially, its battery life. The higher the mAh/Ah, the higher the capacity and theoretically the longer you can use your GPS device in between charges.

Modern replacement battery packs are available that have a higher mAh/Ah than even your original, branded battery - meaning even longer battery life.

CELLONIC® produces a wide range of long-life, high-capacity replacement GPS batteries which can even out-perform the lifespan of the batteries which originally came with your device.

What tools do you need to replace a GPS battery?

There are many different types, shapes, brands and models of GPS devices out there - many of which may require different tools and methods for replacing the battery at home.

Still, if we consider the most common type of GPS - the flat-faced, in-car dash-mounted GPS like many Garmins and TomToms - there are two main tools you’ll need:

Mini screwdrivers. These precision screwdrivers are required to remove any screws which may be holding the back of your GPS device in place.

Spudgers and pry tools. Once the screws are removed, a plastic prying tool is needed to gently prise the back of the GPS device off. They’re also useful for disconnecting and lifting out the old battery.

Many of our replacement GPS battery packs arrive with all the tools you’d need to replace your specific GPS battery at home.

Reliable power when you need it

When looking for a replacement GPS battery, choose a brand you can trust.

subtel®’s CELLONIC® brand of designed-in-Germany battery cells use the best materials and technology to create high-end, heavy-duty, high-capacity, reliable and long-life batteries for all device types.

All batteries ordered from subtel® are shipped within the UK from the day your purchase is made and come with a 3-year manufacturer’s warranty.

If for whatever reason you’re unsatisfied with the quality of our batteries, you can return them within 30 days.
