I have 2 brand new house batteries in 1 bank and a older starting battery
in another. Just recently, I noticed that the Guest 10 AMP Pro Charger
is taking a long time 24+ hours to "finish" the charging
process. I checked the batteries individually with an amp meter and they 13.5 when on the charger
. I am almost thinking that there is some unknown draw that is keeping the charger in the finishing mode, but I don't know how to check for that.
As well, while out on the water
last week, it seems that the batteries discharge way to quickly with the limited power I use. I was told that in an emergency
, the deep cell batteries could be used all the way down to 10%, but after only reaching about 11.5 Amps, electronics
stopped working. What I mean by that is, the GPS
would not turn on or the VHF
did not transmit.
What am I missing here? The charger is less than a year old and as mentioned above, the batteries are brand new.
