Hydrometer questions; new 6V
Well I did the jump to 6V Trojan T145s. I had initially changed out my stock converter with Progressive Dynamics PD4635. In everything I read, this seemed to be the right path for good/better power storage. I am keeping a BatteryLog to better understand and maintain batteries properly: hydrometer readings, voltage, when/how-much DI water was added, general charging maintenance.
This is my problem: I am not getting any better performance than I had with my two 3yr old truck batteries(series 31). After checking with a hydrometer multiple times over 2 months, my battery cells are continually read 1.243-1.250, after full charge(several days) and then allowed to rest 12hrs. I read Trojan’s Maintenance/Testing and it says if your not reading “factory specification of 1.277 +/- .007” there is an issue and should be resolved.
So, after talking with and testing the batteries at the distributor(they claim there is no bad cell and readings of 1.250 is OK), calling Trojan Tech. Department(they said I should get 1.270), calling ProgressiveDynamics(no way to increase voltage), I think I found my problem.
All of Progressive Dynamic’s converters are set to charge a high voltage BoostMode 14.4 then NormalMode 13.6 then StorageMode 13.2.
Trojan’s recommendations for Charger Voltage Settings for Deep-Cycle Flooded/Wet: DailyCharge 14.8 then AbsorptionCharge 14.1-14.7 then a FloatCharge 13.2 and for Equalize 15.5.
I called a tech. help line at a distributor for Progressive Dynamics and he said I should be fine with my converter and that this is the unit he recommends most often. He said there was only one brand of converter that he knew of that charged at 14.7 but that the brand was not built as well as Progressive.
What do you all think, do I need a converter with a higher voltage?
My converter does not do an equalization mode, do I need to? I did read of a, not so expensive, product that use a “frequency charge” to take care of sulfation.
Am I just over thinking the hydrometer readings?
