documentation for specific equalizing recommendations.
TEMPERATURE COMPENSATION
If connected batteries are to see temperature variations during charging, a temperature
compensation kit (
EJ5033-0#
) is recommended. If this option is not part of your
AT10.1, manual adjustments should be made. Refer to the equation and table below for
temperature-adjusted voltages.
temperature-adjusted voltage = charge voltage x K
