As others have already called-out, these high mAh specifications from unknown battery brands are greatly exaggerated. The original 700 mAh battery included with the DC1200 (and DC1400) was made by BYD but discontinued about a year ago. We tested a variety of other batteries and found the LenMar 3.7V, 780mAh to be the best one. Test confirm its a true 780 mAh. You can order this battery from any authorized SeaLife dealer or online at SeaLifePartsDirect.com. Item is SL16134. See attached picture.
Hope that helps.
