Re: Two backup batteries in my system?

An AL 624 is a 1 amp power supply board (at 12V).  Probably added because
the load of all the stuff on your system kept blowing fuses with just the
onboard power supply.  If changing batteries change both.  Also the PS has
no battery monitoring capability so you should date your batteries and
change them at regular intervals.  Three (3) years as long as you have no
power issues used to be a good interval, but I have had a lot of Solex and
DSC (probably the same crap battery) fail in a year to a year and a half.
If you go with a top brand name like Yuasa then three years should still be
a good never a problem interval.
