was able to plug the machine into my computer and it finally charged!  Good job Minelab engineering for putting in a battery that works.  the culprit may have been my USB charger.

I used another charger and another cable and it started charging so I just left it...lets hope for the best.  there is no difference between the charging cable that charges the wireless audio module right!

thanks

I even bought the universal charger with 4 USB ports from Minelab and NEVER used anything but this to charge the machine.

I have used it three times, I plugged it in the first night and I though it charged it fine.  I had not been paying attention and today the fourth time I took it out it flashed BF.

Left charging all day and green light even stays on indicating that it is fully charged but when I turn it on its flashing the battery meaning its less than 5% charged.

very frustrating, going to try another charger that has greater than 2 amps.

Thanks for any comments / feedback
