Minelab Equinox 900
Equinox 900 Battery Life and Full Specifications
Quick answer
The Equinox 900 runs an internal rechargeable lithium-ion battery charged over USB-C, with Minelab publishing a typical runtime in the region of twelve hours. Wireless audio, the backlight and the built-in flashlight all reduce that substantially.
Two questions get asked about this machine more than any other: how long does it run, and what exactly do you get for the money over the Minelab Equinox 700. Both are answerable from published specifications, and this page keeps to those. Where Minelab does not publish a figure, the table says so rather than filling the gap with a number from somewhere else.
The short answer on runtime is that a full charge covers a long day for most people, and that the things which shorten it are the things that make the machine pleasant to use. The battery runtime calculator puts that into hunts per charge for your own habits.

Runtime is a typical-use figure and behaves like one. Minelab does not publish a charge time in the listing material used here, so none is printed. Check the manual supplied with your machine for the figures that match your firmware and region.
What actually drains the battery?
In rough order of impact over a long session.
Wireless audio, screen backlight and the built-in flashlight are the three features most likely to turn a full-day charge into a half-day one.
| Feature | Effect on runtime | What to do |
|---|---|---|
| Wireless headphones | Noticeable over a long session | Run wired when you are near the car anyway |
| Display and keypad backlight | Noticeable if left on all day | Set it to come on only when you need it |
| Built-in flashlight | Heavy while it is on | Use a separate headlamp for hole filling |
| Handgrip vibration | Small but constant | Leave it on if you rely on it, it earns its keep |
| High target volume | Small | Set volume for your headphones, not for the speaker |
| Cold weather | Reduces available capacity | Keep the machine warm on the way to the site |
Directional guidance rather than measured figures. Minelab publishes one typical runtime, not a per-feature breakdown.
What do you get over the Equinox 700?
Three things Minelab publishes plainly. The 900 carries six single frequencies against four on the Minelab Equinox 700. It adds a Gold mode, so four detect modes rather than three. And it ships with the 6 inch Minelab EQX 06 Coil (6 inch) coil alongside the stock Minelab EQX 11 Coil (11 inch), which is a coil most 700 owners buy separately anyway.
Everything else is shared: the same 2.8 lb carbon fibre body, the same 24 inch packed length, the same waterproofing to 16 feet, the same Multi-IQ platform, the same wireless headphones in the box. If you never hunt goldfields and you already own a small coil, the case for the 900 gets thin quickly. The Equinox 700 target ID chart and the 700 depth and coil chart cover the cheaper machine on its own terms.
What should you buy alongside it?
A control box cover first, because the screen scratches long before anything else fails, and Equinox Control Box Cover costs very little. A coil cover for whichever coil lives on the machine, which for the stock coil is Minelab EQX 11 Coil Cover and for the big coil Minelab EQX 15 Coil Cover. A pinpointer, because digging blind wastes both time and turf, and Minelab PRO-FIND 40 or Garrett Pro-Pointer AT both do the job.
If you intend to go in the water, Minelab Equinox Waterproof Headphones is not optional: the wireless set in the box will not work submerged. If you want one pair of headphones across several Minelab machines, Minelab ML105 Wireless Headphones covers the Manticore, Equinox 700 and 900 and X-Terra Pro. The expert setup lists a full kit built around a machine at this level.

Frequently asked questions
How long does the Equinox 900 battery last?
Minelab publishes a typical runtime in the region of twelve hours from the internal rechargeable lithium-ion battery, charged over USB-C. That is a typical-use figure, so wireless headphones, a backlight left on and heavy use of the built-in flashlight will all pull it down. For most people a full charge covers a long day comfortably, and a power bank in the bag removes the question entirely.
Can I replace the Equinox 900 battery myself?
The battery is internal rather than a user-swappable pack, which is part of how Minelab achieves full waterproofing to 16 feet. That means no field swap and no carrying spare cells. Treat a power bank and a USB-C cable as part of the kit if you hunt long days, and follow Minelab service guidance rather than opening a sealed waterproof machine yourself.
Is the Equinox 900 genuinely waterproof?
Minelab publishes it as fully waterproof and submersible to 16 feet, which covers wading, surf and shallow diving. The limit is audio rather than the machine: wireless headphones do not work underwater, so submerged hunting requires the wired waterproof Equinox headphones. Rinse the machine in fresh water after salt exposure, and check the headphone socket cap is properly seated before it goes in.
How heavy is the Equinox 900 compared with other machines?
Minelab publishes 2.8 lb with three-piece carbon fibre shafts, packing down to 24 inches. That puts it in the middle of the current field, which runs from roughly 2.5 to 2.9 lb across the machines in this catalog. The carbon shafts help balance more than they help the total, and a sling matters more than the last few ounces for long sessions.
Does the Equinox 900 come with everything I need?
Close to it. Minelab supplies both the EQX 11 and EQX 06 coils and a set of low latency wireless headphones, which covers most of what a new owner would otherwise buy first. What is missing is a pinpointer, a digging tool, a finds pouch, a control box cover and wired waterproof headphones if you plan to submerge the machine.
