I'm not here in this thread other than to say....It's All Relative...
Batteries are what they are...We can argue types & styles forever...
Charging systems are what they are...We can argue types & styles forever...
We can also argue which are better for each other....
Some of each are better for each....
One thing is for sure...If they don't fit together or one has a problem with the other...None of it will work well...
It's still all about what works together within NOMINAL parameters (within design) for all...

Re: 8D versus 4D
I too have been using GC batteries (for the past five years) with reasonably good success. The reason I qualify my answer is that the solution isn't a good one in really cold weather. I avoid starting my engines when a bad cold front hits Florida. It's just too much stress on them for starting. I did have one mishap over the years, when a battery terminal melted. Not sure if the cause was a loose connection or wrong sized cable end. I switched out the cable connections to ones with the proper size hole to fit the GC terminals and have not had an issue since.
Now I'm thinking about getting an inverter but I doubt the GC solution will allow that, although there have been references here otherwise.1987 63' CPMY - Jubilee

Re: 8D versus 4D
On my 70 here in the PNW I switched to GC's 12 yrs ago, on my second set , 8 per side for 2 32 v systems, 240 v 15 amp inverter runs off the stb'd bank, will not run the fridge/freezer overnite, inverter shuts down on low voltage.
150 amp alternator will let me run the inverter when cruising, fridge/freezer/ice maker. and selectively, coffee maker, one stove element, microwave, dishwasher. etc..
the GC's are 175 ah each and seem to hold up really well if cared for, I keep the main 12 v's pre heated , even in summer, 1/2 turn and they fire.
The GC's do drink water though when really used and that's ordinary tap water which is really soft water here , so, if it ain't broke don't change it.

Re: 8D versus 4D
An inverter will use lower amperage than starting and they are an acceptable alternative. It's the high draw on starting that can be a problem. If you have a pair of 8 or 1271's that have a problem (like unknowingly the air doors tripped or fuel lost prime) you may burn them up before they start the engines. If everything with the engine is always perfect there should be no problem buy we all know that never happens. Thats how we get battery fires.

Re: 8D versus 4D
Everybody should just switch to air starters!

Re: 8D versus 4D
I wonder if you could convert the forward keel tank to hold air pressure??? lol

Re: 8D versus 4D
What about an inertial crank starter like on the old radial airplanes....that would be sweet.
