We use surrette 460's and so do most of the other people around us. Before that Trojan L16's were the battery to have. The surrettes at my parents are
now 6 yrs old and still going strong. We are running a 24 volt system with 8 460's. The house I manage/live has 40 surrette 460's.
I'd like to here more about the Concordes Sunextenders...Are those the really big batteries? |
Wow, 40
Surrettes, that was quite an investment. What are they running, AC? I bet it's a chore to water and clean all of those batteries. How often do you
have to add water?

We have 5 seperate ac units, but they only run when the generator runs, the generator also runs the pool equipment, we have a 2 casitas that have 2
fridges and we also have a large chest freezer, we run the generator 4 hrs a day, to cycle the pool and run the ac as well as top off the batteries.
The main house is over 9000 ft2 and has 15,000 watts of invertors, and 10kw in generation. |
Wow, nice setup. So how many guests stay at your hotel???

I see lots of Optima AGMs in off road applications - seem very rugged.
Take a look at newer generation of AGMs, like Northstar. They are more compact, have a very rugged case and have a neat recessed terinal design.
I've used one (equivalent to a Grp. 27) for two years as the auxiliary battery in my truck, for lights, radio, inverter, etc. with good results.
You for sure don't want lead acid or gell cell for that application.
For deep cycle applications, with heavy loads like inverters, lead acid/water filled batteries are still the most effective/economical - if you are
willing to do a simple maintenance program. I second the comment that it is only an hour or so/month to do. We had Trojan deep cycles as an inverter
bank on our boat for 5 years+, with no issues. If you can't/don't want to do that, then AGMs (like Lifelines) are the way to go - just $$$$$.
Good luck.

FYI, for those interested the Sears Die Hard Platinum is essentially a rebadged Odyssey for less money.
I tried to install one on my Tundra but they do not make the correct size for it yet. Went with a Die Hard International "wet" battery instead.

if you've used only this much water since december your batteries are probably "dead"
my 36 surretts used 3 gallons last month
and average 2 to 2 1/2 gallons a a month
you need to check them with a $1 hydrometer from NAPA auto parts
remember voltage means very little
