The two Die Hard Deep Cycle marine batteries on Respite seem to be dying
(hard!) They were new in May 2011. My Siren MTC monitor is showing voltage
steadily dropping since July from 12.67 to 12.25 volts overnight reading. In
July, the daytime reading was around 12.71-12.72. Right now they are at
12.35 volts daytime and drop to 12.25 overnight. I will put a portable
charger on them for three hours next time I'm at the boat to see if they
will hold a charge. I just purchased two Duralast 29DP Deep Cycle Marine
batteries that were on sale from Autozone. I couldn't pass on the price of
$77! If the Die Hards haven't Died, i'll have a couple of good spares.
