Equalizing Flooded Batteries

NOTE: If battery acid contacts skin or clothing, wash immediately with soap

and water. If acid enters your eye, immediately flood it with running cold

water for at least twenty minutes and get medical attention immediately.

To equalize your batteries:

• Turn off or disconnect all DC loads on the battery during

IMPORTANT: If equalization is programmed prior to float or rest mode,

the Equalize LED will flash and equalization will start prior to reaching

float or rest mode.

Always wear proper, non-absorbent gloves, complete eye protection, and

clothing protection. Avoid touching your eyes and wiping your forehead

while working near batteries. See following note.
