I hope this is the best place to put this. After getting the rest of my solar project parts ordered (sans inverter) I turned to my 4-6V battery bank purchaase. Please don't get into the lithium discussion as SWMBO will not let me go that big. I have been going through a lot of forums (solar/RV/ marine) and what folks are using. Some very interesting projects out there including a guy using the Tesla car battery set up from wrecked vehicles (seems dangerous to me) on his boat.
To make a long thread short I wanted to go AGM if I could find equivalence AH ratings and cycle life. There are tons of brands out there at god pricing until you come to shipping. Unfortunately here in Durango I am very limited on brand choices - especially 6V. I have the typical auto parts stores, Walmart, Interstate dealers by the dozen, and a DEKA (East Penn) dealer. I wanted something in the 250AH (20Hr) rating. This thinned the pack a lot as did ratings and cost.
On several of the forms the Crown brand popped up. US made in Ohio. Overall solid good ratings. However they dont have a dealer near me......BUT they will ship factory direct to me at a reasonable cost. Unfortunately other than reading I have no first hand knowledge.
So here are my choices
Flooded
DEKA GC45 255AH $209.95ea plus $27.50 core plus tax 7% give or take. Local dealer https://www.eastpennmanufacturing.co...Flyer-0250.pdf
Trojan T145 260AH $280.51ea plus $29 core + local NM tax Dealer 75 miles away http://www.trojanbattery.com/pdf/dat...ata_Sheets.pdf
Crown CR-260 260 AH $142.17ea plus $79 shipping (factory direct) CR-260 PowerSheet_D06260_0213-1.pdf
AGM
Crown 6CRV260 260AH $240.86 ea plus $79 shipping (factory direct CROWN1-PowerSheet-6CRV260-sec-1.pdf
I could not find any other AGM's in the AH range.
All of the above are GC2H size, and I plan to use a vented quad battery box.
Thoughts on these or are there others?
In reviewing the Crown data sheets they appear to have good cycle life, but was surprised the flooded has longer life. (I wonder if I red the graphs correctly) The Trojan cycle life is about 1/2 of the Crown. I am also aware the AGM can withstand a deeper discharge (50% flooded, 80% agm).
I don't plan on being a heavy battery user so I am guessing I would typically be in the 20% cycle for state of charge for the 4 battery set up. We don't watch much TV and would be sparingly using the microwave, etc We do have 2-CPAPs nightly run off of 12V.
As I am not battery savvy and I am not the best at maintenance. Please give me your honest thoughts on my choices.
Thanks Keith
