ok thanks all. another question. is it possible to start the 20GMF with a
handle? I think i will get the surettes load tested and decide whether or not
to replace after that and replace the starter battery with a group 24 (if it
fits). We are also hoping to do more cruising and spending time on the hook, so
we are looking at get set up with solar as well.

We have two T12 136ah ( slightly larger and heavier than a group 27 ) Rolls
house batteries which are now in their 12th year of service. I was thinking
they were near their end of life but a battery equalization last year seems to
have given them a new lease on life. We replaced a Rolls starting battery after
11 years. Ed

Our new (to us) 33-2 has a couple of Surette Group 27 Deep Cycle Batteries of
indeterminate age in plastic battery boxes with no lid and a Canadian Tire 22NF
starting Battery (In what looks like a home made wooden battery box).
My first instinct is to replace the deep cycles with Interstates and upgrade
the 22NF to a Group 25 Marine Starter Battery in proper battery boxes (I have
seen first hand how quickly a dropped wrench landing on exposed 12v battery
terminals can go very bad).
The charger is a relatively new looking Professional Mariner ProSport 20
Heavy-Duty Marine Battery Charger. Both banks are monitored by a cruising
equipment company e-meter.
My questions are 1. Does anyone have 2 G27s and a G25? Is there room?2. Someone
told me the Surette are very good batteries with longer than average life and I
shouldn't be in a hurry to replace them. Experience ? Thoughts?3. Anything else
from your experience I should be thinking about?
Cheers,Doug
