Minelab Equinox Battery Replacement Instructions

Recommended Posts

Get the full scoop with photos at the Minelab Service Parts website. So far nobody appears to be selling the 3011-0405 battery but someday it will be something to possibly have to deal with. So far though I've not heard of any battery longevity issues... mine still give me a full day service and they are the oldest in the country.

Thanks Steve for the link. Looks easy enough. Mine after almost two years still holds a charge like new. Or at least longer than I can detect.👍

The battery looks like a single 18650 with leads soldered on. If the replacement battery isn't pretty cheap I'll probably be looking to diy when the time comes. I can't see myself wanting to pay $100+ when I have a dozen of them sitting around the house.

Anyone have a cost on the Factory replacement?

A search for the Minelab part number turns up nothing but the Minelab parts website - none for sale. A dealer might be able to find out.

I added a picture of the battery to the original post and here is a closeup of the label...

I feel it is awesome that Minelab has posted these instructions on battery replacement.  Not many companies share this type of information with their users.  This just goes show they really care for their users.

Note that the Minelab battery has 3 leads and the 26650 has 2 leads.  The third wire may, possibly, be used for temperature sensing to protect the battery.  My guess is it would be wise to purchase the replacement battery from Minelab and get the right number of leads and the connector already installed.

Point taken, and it's a good point, but I use mine less than many. By the time I need a replacement I expect there will be plenty of detailed tutorials out on exactly how to do it.  The internet is great for some things, and I'm not the only DIY type person out there.

Obviously if minelab prices the replacement at double the cost of the battery or less it's a no brainier, I'll just buy the replacement,  but if they do the typical 4x+ price I'll figure it out.

More than likely the cell has shrink wrapped into it a protection circuit (Chip) to prevent over charging/discharging. Its a single cell so there  is no need to balance charge like the multi cell LiPO batteries. Will be hard to tell until someone removes the shrink wrap and exposes what's underneath. Could also be a empty lead if the battery charging circuitry in the detector is designed accordingly.

But agreed until more facts are known I;d stick with OEM replacement, LiPOs are a fire danger if handled improperly while charging. 

 

Edit;

I have a fair amount of experience with LiPO batteries in the RC and Ham Radio hobbies I partake in, but not claiming to be a authority by any means

      Hi Guys,
      What sort of set up are you guys using on the equinox 800 for gold jewellery in parks etc.
       
      Regards Pinpointa.

      This was on TV in New Zealand tonight about a guy finding a gold sovereign with his Nox worth about $50,000 NZD, about 33,000 USD.  It was an Aussie minted coin.
      The video even has what I see as a typical Garrett user in it 😛  Just kiddin'

      Has anybody done better with the Turkish machines on US silver coins in a park setting?

      Hi, long time lurker, first time poster. 
      So the manual only tells you that certain modes have “low frequency weighting” and “ higher frequency weighting”. Otherwise a chart shows the adjustable settings that have been optimized for scenarios they describe presumably.  Understandable, we get some presets.
      My question in title in other words: Assuming I set all adjustable settings the same for Park 1 and Field 1 (or Park 2 and Field 2), would these two modes be essentially the same? Or would the non-adjustable portion of the “1” modes and the “2” modes still be different?
       
      Thank you for your insight.  If this has been covered in another post, a link is appreciated as my search did not lead to an answer.
