battery problems

[lovecindy6710]

i have an exmark mower thats 60 inch deck and ive bought multiple batteries for it but the die so quick. i dont know what the problem is.

Start the mower and take a multimeter and put the red lead on the + terminal and the black lead on the - terminal of the battery, and let us know what the DC voltage reading is.

Believe you may have a bad stator (alternator) have it check out.
