I recently inherited a Minelab Excalibur Sword detector. This thing looks brand new all but the battery pack being corroded and bad. I'm thinking about buying a battery pack for it but they're not cheap. And I don't even know if it works. Does someone have a spare alkaline battery pack that I could buy or borrow to test it? If you let me borrow it I'll pay for shipping both ways. Thanks for any help! Morgan

Look on eBay for a cheap lab dc power supply. You can use it to test your detector, power battery chargers, a multitude of things. 0-30V range and get look for a current limit knob on it too. The meter will tell you current limit or current demand. You will establish a normal current reading and then know if something is not right later.
Buy a lithium battery pack from an online RC dealer that will fit in the stock housing. A good charger that works on a wide range of battery types is like 35$ on eBay before tariffs kick in. Mine is a BC6.

I just want to give a shout out to fwcrawford he sent me a alkaline battery pack for me to test my Excalibur Sword out with and it fired right up. Thanks very much Felix and your battery pack is on its way back to you. So after knowing that the Excalibur works I ordered a 8AA battery pack for it and a 9 volt cable end cleaned up the old rechargeable battery pack and wired in the 9 volt battery cable and it works great now. I'll try and post some pics of the Excalibur later it's a closet queen

Just a heads up..let me know when you get it and I'll do a inspection check list for you to make sure all is good to go into the water. the seals maybe bad.. and the sword case after 25 plus years can show signs of leaking around the knob shafts tubes, little guys but the inside where they are glued cracks..i can post pictures and all
