 These chargers appear to have a 3 hour absorption duration.  This is usually insufficient for lead chemistries, but still longer than the 2 hour duration of the DCC series above.  From the manual: These chargers appear to have a 3 hour absorption duration.  This is usually insufficient for lead chemistries, but still longer than the 2 hour duration of the DCC series above.  From the manual:

 +
 +  * configurable output current - 60A/50A/40A/30A/20A/10A
 +  * voltage-sense triggering rather than D+
 +  * 10-300min boost duration in USER mode
 +  * 120min boost duration still hard-coded in predefined lead-chemistry modes, BUT will drop to Float if output is less than 3A (ie Absorption termination based on endAmps)
