Recently I had a battery charger installed on our boat , the electrician and I started on with the operation and I forget why but I checked the voltage on the battery's . The house bank (open flood) was at float 13.2 and the starter batt. (sealed acid) was at 12.7 . The charger we were replacing was the sealed electronic multi stage type and was about 15 yrs. old . Normally that charger kept both batts. floating the same , 13.2 . I thought doesn't matter because we are installing a new charger , (house and starter are about 3 yrs . old) . Now it's the same starter will not charge higher than 12.7. My first thought is the starter batt. is on it's last legs ?
My electrical guy said open flood and sealed acid mix will be ok with the new charger , I don't really believe him . Is he wrong ?
And lastly how critical is the float voltage ? With my new charger it's programmable , I'm still learning to program it . On one setting it was floating 13.2 need 13.5 on another setting it was floating 13.8 .
Thanks , Mark .
