Batteries should be checked on a regular basis. The company recommends every month. To check the Batteries simply undo the caps and check the water levels. The proper water level is just over the “fins” in the battery. If the batteries are low, add distilled water only to just over the fins being careful not to spill any water on the batteries. Gloves and eye protection are highly recommended when performing this task. The battery terminals need to always be tight. Check them and if loose do not over tighten. Tighten only to where nut is snug on terminal. Make sure the wrench you use does not touch a positive and other metal or the negative cable at the same time. Make sure clamp holding battery pack down is also snug. Do not over tighten. Battery cables should be kept clean of corrosion.
