TM-2030 Technical Manual

TriMetric function is intended for use primarily for systems that require manual equalization--and reminds you to perform
this after the programmed time. Placing the charger in "equalize" mode involves extra charging after the batteries have
reached the "charged" criteria which allows the voltage to rise extra high for a period of time--for example the Trojan
Battery Co. recommends charging to 15.5 volts (for 12V systems--double this for 24V systems) and keeping the batteries at
that level for 2 hours. Other manufacturers may have different recommendations. It is usually advisable to check water
levels in the batteries after equalization, as it causes some water loss. After equalization has taken place you must
manually reset the "days since equalized" display (by pushing “reset” when the days since equalized” extra data is
displayed)--this does not take place automatically. This will turn off the "time to equalize" reminder, which will
reactivate only after another equalization period has elapsed.
For “liquid electrolyte” batteries: Every month or so check the water levels in the battery cells to make sure that
the water covers the plates. It is not good for the batteries if the level drops below this level.
