Subckt Library Item #111 is not initialized properly.

The EasyEDA SPICE model and subckt library list (last updated170710 (YYMMDD)) : Sheet1 lists '111 BATTERY_LEADACID_12V_7AH subckt 10-20 18:15'. I created a 'public' circuit 'TestSimA' in my user area. My voltage probes do not display any voltage on the graph. Looking at the 'subckt' it appears the line establishing a 6 cell battery is disabled. I haven't figured out where/how to find this subckt so I can edit it. Concise problem statement: 12 volt 7ah battery is not initialized to 12 volts. Steps to reproduce bug: 1. Load 'TestSimA' from my user area. 2. Run the document. A graph is generated, with two voltage identifiers, but the voltages are zero! Results: The battery is 'DEAD' (improperly initialized). Expected results: 12VDC available to power the circuit simulation. Voltage curves should be displayed on the graph. Browser: Latest Chrome

Hi Gary48, This is not a bug. The model is for a lead acid battery. It has to be charged up before it can be used. A simple way to do this is to add the following spice directive to your simulation: `.ic V(volprobe1)=13V` This will charge the battery so that from time t=0 it will exhibit a 13V open circuit terminal voltage. For more information please see: `### Using the `.ic` spice directive to set an initial voltage condition on a net 43` https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub#h.3l18frh To make an editable copy of the model please see: `# Device models 60` https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub#h.43ky6rz
