Can you use rechargeable batteries in a metal detector?

You certainly can - and it might be a good idea!

Most metal detectors run on standard AA batteries, but there are some that are specifically designed for use with rechargeable batteries. The advantage of using rechargeables is that you'll never be caught without power - assuming you remember to charge them up, of course! - and they're also more environmentally friendly than disposable batteries.

If you're thinking of using rechargeables in your metal detector, make sure to check the manufacturer's recommendations first. Some models may not work with certain types of batteries, so it's always best to err on the side of caution. And, as with anything else electrical, if in doubt, consult a qualified professional before taking matters into your own hands.

What kind of batteries does a Garrett metal detector take?

The Garrett metal detector takes AA batteries. Most of the time, you will need four AA batteries to power your device. Meanwhile, some of the models require only two AA batteries. It actually depends on the model that you have. 

If you are using a detector for the first time, make sure to read the user manual to check how many batteries are needed to power it up. On average, a new set of alkaline batteries can give you around 20 hours of use. However, if you want to extend its life, consider using lithium batteries, as they can last up to three times longer than regular alkaline batteries. 

When choosing AA batteries for your Garrett metal detectors, always go for quality over quantity, as this will ensure that your detector is always running at its best. Look for batteries that are made by a reputable brand and have a high voltage rating. This way, you can be sure that your device will last long and perform well each time you use it.

How long does a metal detector battery last?

This will depend on the type of battery that is used in the metal detector. Some detectors use disposable batteries, while others use rechargeable batteries. The lifespan of a battery also depends on how often it is used. Typically, disposable batteries will last for around six hours, while rechargeable batteries can last for up to 12 hours. It is important to keep a spare set of batteries on hand in case the current set runs out.

When it comes to choosing the best battery for a metal detector, there are a few things to consider:

  1. Determine what type of battery the detector uses.
  2. Decide how long the battery needs to last.
  3. Consider the cost of the battery.

Some disposable batteries are more expensive than others.

Rechargeable batteries tend to be a better value in the long run since they can be reused multiple times. However, they do need to be charged regularly in order to maintain their power. Disposable batteries are a good option for people who do not have access to a power outlet. They are also a good choice for people who do not want to worry about charging the battery.


If you’re looking for a battery that will last a long time and provide good power, then alkaline batteries are the best option for metal detectors. However, if you want to use rechargeable batteries, NiMH ones are a good choice. They don’t have as long of a life as alkaline ones, but they are still a better option than disposable batteries.

Finally, it’s important to keep your batteries in good condition. This means keeping them clean and dry and storing them in a cool, dry place. Follow these tips, and you’ll be able to get the most out of your metal detector batteries.
