turn off the inverter?

My 2-8D Lifeline AGM batteries are 7 years old now and still going strong. Good Luck, TomC

You would think that the battery mfgs would put the charging specs out there readily available, but being a curmudgeon like Handybob, I think they want us to screw them up so we have to buy new ones sooner.  They relish the method of keeping us uniformed.  David

Ain't it the truth! And battery mfgs are not the only ones!    I made it a practice sometime back to copy and preserve just about ANY specs I happen to find; even for stuff I don't own..... Hey, I might own one someday!    The reason there are fewer and fewer specs is because there are fewer and fewer people who want them or know what to do with them. It's a sad state of affairs.

I am going to set my bulk rate at 14.7 and keep a close watch on the electrolyte.

It appears 5 years is about average for a set.  7 would be nice, but battery replacement is just another joy of bus ownership

Did you check their main website for the flyer for your particular batteries?

https://www.eastpennmanufacturing.com

I found lots of information there, but not sure which is for yours.

That is similar to my method.  What is your bulk charge volts? and what is your float volts.  I have been using 14.4 bulk and 13.1 float.

I checked the inverter and the float is 13.7 and than I did a eq. charge and that is 15.8 v but it was not long ago that I did a eq charge so it did not take long to go through that

did not see a bulk charge as the batteries were fully charged
