When you are dealing with your Metal Detector, Batteries are as important as other parts of your machine! In fact, quality batteries that can last longer will allow you to use your machine for a long time …
… And this is extremely useful, especially if you are dealing with long hours of hunt where you are definitely going to need your batteries!
How long does a metal detector battery last?
Most detectors’ batteries can give you 20 to 30 hours of operation, depending on the battery type and quality of the detector.
This could be shorter if you are dealing with trashy locations where your machine will give you a lot of false signals. Or longer if you are using a quality machine known for its energy consumption efficiency!

Best Batteries that last longer …
1. XP Deus
The XP Deus (Check it Here on Amazon) is known to have one of the best battery life. Here are some of the features of its battery life:
- Battery for the Wireless Headphones: 27 Hours
- Remote control: 27 Hours
- Search Coil: 15 Hours on average
The search coil’s battery life may vary depending on the modes used. Here’s how the detector’s battery life looks like according to frequency and power selected:
|Selected frequency||Power Level||Battery Autonomy|
|4 kHz||None||11 Hours|
|8 kHz||1||19 Hours|
|8 kHz||2||13 Hours|
|8 kHz||3||11 Hours|
|12 kHz||1||19 Hours|
|12 kHz||2||13 Hours|
|12 kHz||3||11 Hours|
|18 kHz||1||20 Hours|
|18 kHz||2||14 Hours|
|18 kHz||3||11 Hours|
The best part of XP Deus is that the detector is made in such a manner that there will be no deterioration in its performance even when the battery level is low!
2. Garrett ACE 400
Depending on the available information I have, the Garrett ACE 400 (Check it Here on Amazon) could go up to 20 hours.
3. Minelab Equinox 800
The Equinox 800 (Check it Here on Amazon) is my favorite machine! It has got a built-in lithium rechargeable battery which is powerful …
… On one charge, the battery can run for at least 15 hours.
How long batteries last per Hunt?
Batteries of detection machines tend to last for at least 12 to 18 hours one each hunt.
It is important that you begin with the right alkaline batteries for your detector. You should consider using Panasonic Evolta batteries for those detectors that use AA batteries or the Panasonic Digital batteries for the 9-volt detectors.
These batteries are not only priced similar to the standard alkaline batteries for detectors but also provide a significant increase in battery life.
If you are using rechargeable batteries, then they also last for at least 12 to 15 hours. However, some rechargeable C batteries for detectors such as the Eagle Spectrum only tends to last for five to six hours.
So the battery life also depends a lot on which detector you are using and what conditions you are detecting in.
How to help your battery to last longer?
An excellent way to conserve battery life is to use good headphones so that you can cut down on speaker use, which uses up a lot of battery. Headphones also help cover your ears and cut down any noise from the environment, thus drawing less power than the speakers on the detector.
You should also fine-tune the detector settings. Review the detector manual and follow the manufacturer’s tips for extending the battery life. For example, most PI detectors require more power as you keep increasing the pulse width.
It is also better to keep your detector volume at a moderate level and then adjust the volume on the headphones. As you increase the sensitivity of the detector, this also decreases your battery life. So find the optimum setting and get the most out of your detector.
