Yes and no....Using the winch is one way of draining the battery and having aftermarket lights/accessories that exceed 10amps of total draw can drain the battery as well. I have 5 different led lights set up on my machine, and have plans to add a stereo as well, so I am pushing the limits of the charging system! Dead batteries happen....and when they happen on one of these machines you will see what a PITA it is to try to jump start them (the cover alone will teach you how to cuss if you want to remove it especially with oversized tires) and there is maybe 1.5 inches of space to try to clamp jumper cables onto the battery without touching the metal frame!
