PD9200 Series "manual override" question.

Even on 40-50% discharged batteries, the wizard does not always start in "boost" mode,.....why I don't know. Most times it does, but I'm always glad to have the override when it doesn't. And this is the same for the 91, and the 9200 series. I have had both, and they both operate the same. Having said that, everything else the PD does, it appears to do it right. My batts live on a PD 24/365, and the last batts were 8+ yrs when the MH was sold.

I know of few manufacturers who provide a

Here! Blow Me Up!

Actually it has not failed. It was just recently installed and not been on a maiden voyage. When we boondock I do not have a computer to ask these type of questions in case of a failure. So I like to do my research regarding how new things work. Murphy seems to tag along but although knowledge can be a dangerous thing the scout in me likes to be prepared.

Under what conditions did the 9270 fail to boost when expected?

With a user who has his battery metered and knows about battery charging basics, temperature effects, etc., he can do much better than PD's not all that sophisticated charge wizard sensing capability and algorithms for efficient charging. For somebody without any battery knowledge or real time electrical data, I agree with not using the button. I think a person with the battery knowledge and metering will realize this on his own. The PD converters often do have trouble maintaining their output at 14.4 volts, a totally different issue unrelated to manual vs. automatic operation.

Thanks! So BFL13 it has nothing to do with the possibility that the PD9200 cannot sustain the 14.4vdc for extended periods? "They leave out the situation where you are on limited generator time and want a fast charge and to get that you need to boost the voltage, but they provide for that with the Charge Wizard "if you must." Sure would be better if they explained it that way.

They figure you are on shore power and it is easier on the batts to be at 13.6 than 14.4.

They figure the converter would be at 14.4 itself if the batts needed that, so when you boost it to 14.4 when it was at 13.6, then you will cause un-necessary gassing.
