I  have been using the AW-2200 in an older White's 6000 XL Pro machine. The battery life is most impressive and I think the physical design is excellent. The battery is very easy to remove from the detector and significantly lighter in weight than standard batteries or factory rechargeable packs. Every ounce of reduced weight adds up to a more enjoyable detecting experience out in the field. My 6000 XL pro just keeps on purring along on this battery for days of hard hunting for many hours. My 6000 just runs better on this battery - more stability and I swear even a bit more usable depth (vs the factory rechargable pack - which frankly doesn't compare, or regular alkaline batteries) due to the consistent power the machine is drawing from this fine piece of engineering. I have found the same result as another reviewer has stated as well - that the battery seems to have no diminished capacity when recharging before it has fully discharged- excellent! Again I will say that I am very impressed with this fine product - so much so that I look forward to getting the new battery that will be available soon for the new E-trac a I just purchased.

Great job RnB!

I used the AW-2200 Prototype battery on several different Whites machines (White’s MXT Pro, M6, XLT and DFX) , but the primary testing was done on my Whites MXT Pro. The battery functioned flawlessly in the machine, and the length of service was outstanding, I believe the average run time I would get from a single charge was approximately 60 hours and I actually only ran it completely down to discharge 2 or 3 times in the 6 months of use.
