TMG, the 808 is quite different. Because its made to charge the larger C and D cells also, (near the top of the charger) there's tons of room/spacing between AA's & AAA's at the bottom of the charger. If, however, you were charging C's or D's, you might have the same issue. Don't have any so have not tried. Must admit, the AA's look lost way down there in the bottom of the charger. Look at the dimensions of both. The 808 is quite a bit bigger. The more mass/surface area/space between cells probably results in better cooling.
