Why XP Deus Battery Replacement?
Like many such devices, the headphones, the coils and remote controls in XP Deus Metal Detector are all lithium battery powered.
With a long lithium battery life of anywhere between 20 hours to 27 hours or so (depending upon what you read and how you use it), not everyone will want to be bothered to make changes. But – like me – some do!
In fact, according to the product specs you can expect the following:
- Remote Control – up to 25hours
- Headphones – up to 17hours
- Coil – up to 20hours
These operating times depend on the programs and frequencies used. The instruction manual details it all a bit more. Of course, all three of these units can be fairly conveniently and quickly charged in about 3 hours!
But who wants to be limited on search time? And who wants to stop and recharge?
Not I!
More Lithium Battery Power?
Let’s Go!
This is for those who need to replace the lithium battery in the XP Deus Coil because they would like their XP Deus metal detector to work longer.
For my device, I opted to go for a lithium battery with a larger capacity. It’s unlikely to be recommended by the manufacturer, so do so at your own risk. Not sure if it voids the warranty, either – so keep that in mind.
But if you’re interested, this is what I did.
Alternative, Larger Capacity Lithium Battery
Here are some photos of the battery replacement procedure:
These are new batteries with a larger capacity – 1000 mAh.

Batteries similar to these can be purchased on Amazon – and they’re not at all expensive.

Also, one of my friends did a DIY lithium battery replacement changeover in their 9” search coil. They also used a larger size lithium battery (60 mm x 18 mm and 9 mm thickness) and capacity for longer life during prospecting and it perfectly fitted to the available housing slot, as you can see below:

Warning Handling Lithium Batteries
You may already know this, but if not – lithium batteries have to be handled with care. They also need to be disposed of properly. Mishandling (such as crushing, bending, or puncturing the casing) can lead to fires or explosions. Consequently, this could lead to personal injury and/or environmental harm – the risk is due to the flammable nature of the components and the toxic materials they contain.

My name is Paul and I am the founder of Detector For Metal, a dedicated resource for metal detecting enthusiasts seeking to uncover historical treasures and connect with the past using the latest technology. As a stay-at-home dad and family man, I’ve found metal detecting to be the perfect hobby that combines family adventure with historical learnings for the whole family.
As a father, I’m deeply committed to passing on this hobby to the next generation of detectorists, starting with my own children. I share advice on everything from metal detecting with kids to exploring the top 10 metal detecting sites you never thought about. My methodical approach to the hobby goes beyond the thrill of discovery—it’s about creating family traditions while preserving history and sharing the stories of those who came before us.
