PROGRAMMING YOUR EC2000 CONTROL 
Using Extended AH for Opportunity/
Fast Charging on the ECLIPSE II 
PLUS  
 
The Extended AH Feature of the Eclipse II Plus 
allows the user to Opportunity/Fast Charge  bat-
teries at charge rates from 20-50A/100AH, as 
long as the actual charge current is within the 
nameplate rating of the charger.  Batteries that 
are rated below the maximum AH rating of the 
charger can be Opportunity/Fast charged at rates 
higher than the nominal 25A/100AH. 
 
Using a BID 
When a BID is installed on the battery, it must 
have the “Battery Start Amps” set to a value 
between 20 and 50. The charger will then sup-
ply a start current equal to the Battery Start 
Amps setting times the AH rating of the battery 
that is programmed in the BID divided by 100. 
See the example below: 
 
Battery 24 cell, 600AH (24-100-13) 
Charger           1050EC3-24DP 
 
 BID Settings: 
 
 BID Cells                        24 (item 51) 
 BID AH                           0600 (item 53) 
 BID Battery Type            08 (item 54) 
 BID Start Amps              40 (item 58) 
 
 Resulting Charge Rates: 
 
 Start Amps - 6 x 40 = 240 Amps 
 Finish Amps - 4.5 x 6 = 27A 
 Charger rated start amp = 261 
 
Not using a BID 
The example below describes how to accomplish 
Extended amp-hour charging without the use of  
BID Module on the battery. 
 
Battery 24 cell, 600AH (24-100-13) 
Charger            1050PACH3-24P 
 
Charger settings: 
Charger Fixed AH       0600 (Function 36) 
Charger Curve Type   08 (Function 38) 
Fixed Start Amps     40 (Function 65) 
 
Resulting Charge Rate: 
 
Start Amps  — 6 x 40 = 240 Amps 
Finish Amps  — 4.5 x 6 = 27 Amps 
Charger rated start amp = 261 
 
 
 
Using “No Gassing” to prevent 
excess  gassing in Opportunity and 
Fast Charge applications  on the 
ECLIPSE II PLUS  
 
The No Gassing Feature of the Eclipse II Plus 
allows the user to Opportunity/Fast Charge  bat-
teries until the battery reaches the gassing por-
tion of the charge curve.  At this point the charger 
stops delivering charge until the “No Gassing” 
interval has elapsed. 
 
Using No Gassing 
 
3 Shift Application 
When Opportunity/Fast charging batteries in a 3 
shift application and when  it is desired to not 
charge the battery above 80% on the work days 
while finish and equalize charging on the week-
ends, the No Gassing interval should be set at 
or above the value of the longest break, meal or 
shift change period where the charger is con-
nected to the battery. Typically a setting of 2 hrs 
would be adequate for this type of application. 
 
2 Shift Application 
When Opportunity/Fast charging batteries in a 2 
shift application and when  it is desired to not 
charge the battery above 80% on the work days 
while finish and equalize charging on the week-
ends, the No Gassing interval should be set at 
or above the value of the longest period where 
the charger is connected to the battery. Typical-
ly this is the length of the “off shift” and a setting 
of 6-8 hrs would be adequate for this type of 
application 
  
1 to 1.5 Shift Application 
When Opportunity/Fast charging batteries in a 1 
to 1.5 shift application, time is available to 
charge the battery fully (100%) each day and 
maintain safe battery temperature levels.  In this 
type of application the No Gassing interval 
should be set at or above the value of the long-
est break, meal or shift change period other 
than the “off shift” where the charger is connect-
ed to the battery. Typically a setting of 2 to 6 hrs 
could be adequate for this type of application.
