As many of you know, I have had house battery issues. I have resolved this matter, and recently received delivery of 3 North Star 210's from Energy 1 Batteries in Portsmouth VA. These batteries are unique in that their output is the same as 8 D's, but they weigh 25% less and are 40% smaller, mainly in width. Their dimensions are approximately 5" wide, 10" high and 20" long. Therefore, for those of you who do a lot of dry camping, you could double your battery capacity due to the fact that you could put 2 North Stars in the place of 1 8D. I have had several conversations with Harris at Energy 1 Batteries, and he has offered to extend special pricing to members of this forum. The pricing will depend on where in the country you are, if he has a distributor in that area, etc, etc. Harris is extremely knowledgeable and very helpful. I would urge anyone who needs to replace the house batteries to contact Harris and consider these high tech batteries. They are 100% made in the USA. More information is available at AGM batteries, Marine Batteries, Heavy Duty Batteries, dry cell batteries (http://www.energy1batteries.com). His phone number is 1-757-673-7200. I know Harris will be out of the office until Monday.

Greg, thanks for the info. I understand if you don't wish to give prices but generally how does the price compare to a standard 1400 CCM, AGM battery? How does the life cycle compare?
Kent, prices are extremely competitive with other AGM's. This battery's biggest advantage, in my opinion, is its state of the art technology as well as its higher power output in a very compact size. Information is available on the website I posted, but as I recall it can be discharged to 50% of power 800 times.

Specs look good - I will have to take some measurements, but if I could get 3 where I now have 2 with good pricing I would go for it. I'm lucky as they have multiple distributors in FL I could drive to in a couple of hours.

Subject: [Sentoa] AGM Batteries - A Cautionary Tale
Message-ID: <20090623085212.ulutifsgg0cws08c at webmail.novusnow.ca>
Four very expensive Northstar NSB M12-210 AGM Batteries have died
after only one season of operation as my house bank.
I set my Xantrex MS2000 Pure Sine Wave Inverter/Charger to AGM mode
thinking that I would be OK. It turns out that the Xantrex supplied
13.45v on float all winter, and these batteries require 13.62v. When
the Northstar rep denied me a warranty replacement, he said that my
float voltage was WAY LOW, and that it was my fault I had ruined the
battery. Sulfation is not covered by the warranty.
It turns out that these units are extremely susceptible to sulfation.
In fact, Boat Electric in Seattle (not the company that supplied my
batteries) strongly recommend using a Nanopulser unit to shake the
sulfation off as you go along.
The Lifeline AGM batteries that I used for starting and bow thruster
are OK. Guess I will switch my house bank to Lifelines, which are the
units that Nordic Tug have decided to use on new boats.

After talking with my battery engineers/supplier, they feel as I about the .17 Volt DC low causing the issue refuaing warranty due to sulfation a horse hockey excuse.
Makes me more and more glad I went with the Gels, I was not aware of the sulfation issue with the AGM. Just like the lead acid in that respect, so what is the great about AGM? :(
As I have felt, Concerning batteries, there are many opinions and little facts.
Of course, I am opinionated. ;D
Yes Dave...in my opinion you are opinionated...but I agree with you on the GEL technology...IMHO... :-X
Well more fuel for the issue, Energy1 is a branch of Western Branch Diesel The Detroit Diesel Dist. in Va, and per Northstar Battery info, that battery is to be maintained at 13.50 VDC and has a shelf life of 2 years. Now since it was maintained at 13.45 instead of the 13.50 VDC, makes me feel stronger about the Horse Hockey (BS) comment earlier.
That is one way to have no warranty claims, just refuse everyone / everything.
Still glad I went for the Gel setup. Down on AGMs for me :o
As usual FWIW
Reason I choose gel cell technology:

Does depth of discharge affect cycle life?
Yes! The harder any battery has to work, the sooner it will fail.
* You may experience longer or shorter life based upon application, charging regimen,
temperature, rest periods, type of equipment, age of battery, etc.
Typical* VRLA Battery Cycling Ability vs. Depth of Discharge
Typical Life Cycles
Capacity Withdrawn Gel AGM
100% 450 150
80% 600 200
50% 1000 370
25% 2100 925
10% 5700 3100
This page:
.: Battery Specifications : Energy 1 (http://www.energy1batteries.com/specs.html)
says the NSB210FT's capacity is 185 amp-hrs. A Lifeline
GPL-8DL capacity is 255 amp-hrs. This does not appear to suggest I could double "capacity" (amp-hrs) with two NSB210FT's for every Lifeline
GPL-8DL. It looks like its more like 370/255 = 1.45 not 2.

Hi Dave M,
That Horse Hockey saying must be a Virginia deal! My Dad used it quite frequently. He was born, and raised in Virginia. Have not heard it much lately. Just when I'm letting my son know it's a HH, or BS story.
