45 Amp converter

Ok, my new battery is shot...im using the PD9145A Power Converter. It appears to be wired correctly & both fuses are good.

I put in another new battery today, I can literally hear the battery boiling within minutes and within 15 minutes its boiled over. Shouldnt it cut off/stop charging automatically?

This is the unit im using PD9145A - 45 Amp Electronic Power Converter

FYI: I put in an older battery & Im using a 1.5 Amp Three Stage Onboard Battery Charger/Maintainer for now. The 12volt seems to work ok, but this is obviously temporary.

Put a voltmeter on the converter. It should not put out more than 14 v. This is a 3 phase converter I don't know enough about the electronics to tell you how to check. Get in touch with Randy at BestConverter - Converters, Inverters, Electrical Supplies, Electronics.

You should never, ever "hear the battery boiling" with a modern 3- or 4-stage converter/charger. It sounds like your intellipower unit is done for. How old is it? I think they have a decent warranty. 2 years if I recall correctly.

As I recall, the 9145 you have had the "charge wizard" as an option so it was capable of a 3 stage charging, but only if the optional part was purchased. I am not sure how available those are now. PD should be able to tell you that. But you may not have the 3 stage feature enabled is my point. However, even without the charge wizard you should not have boiling on a new battery. Sounds like something is wrong with the PD converter/charger.

The newer 9245 comes with the "charge wizard" included.

I am not sure about a 9145 but I have a 9245 with a charge wizard. In this set up the converter will automatically change phases, but the charge wizard can be used to manually change phases.

The 3 phases are basicly 1.charge- higher power when battery is low 2.maintain-lower power to maintain full charge and 3. store-minimum power when there battery draw is low and battery is charged.

It's possible that the battery was shorted internally.

The only way to know what's going on for sure is to measure the voltage and current output from the converter using reasonably accurate instruments. If the voltage is excessive, the converter is bad. If the voltage is normal or low and the current is inexplicably high, the battery is shorted.
