[RE-wrenches] Hawker versusu MK

[Exeltech]

Several years ago, I designed and built a solar trailer I call the “Solar Shuttle”. ( http://www.ntreg.org/projects.htm ). In it, I  use a combination of Rolls-Surette and batteries made by Crown Battery in Ohio.  The Rolls serve as the primary batteries for the main inverters.  The Crown batteries provide power for three portable solar electric systems ranging in size from 1 to 5 kW (with Exeltech sine wave inverters attached.)

Batteries in portable applications such as this are not treated kindly, either mechanically or electrically.  Frankly, it’s abusive.

In spite of the rough treatment, both the Rolls AND the Crown batteries have done a superb job.  By the way, as for “being around for a while” .. Crown has been in business since 1926 .. AND they're made in America.

My opinion -- No charge (and no pun intended).

I don’t have any experience with this brand of battery but wanted to add my battery story to the thread.  
 
I have a bank of Power Battery brand batteries at my house and when I got them the price was right, I had a good relationship with the distributor and the warranty was 10 year (5 full, 5 prorated). A couple of years ago they went out of business and with them went my warranty.  
 
At this point I don’t think I’d buy from any manufacture who hadn’t been around for a while.  I’d mostly stick with Trojan and Surrette.
 
 That’s my $0.02  
 
Thanks,  

Will

Friends:  
 
We are shopping for industrial, flooded, lead acid batteries. We are considering 12 volt packages in the 1800 AH range. Under consideration are:  
 
Hawker 12-25W-23S at 1705 AH or MK 106M1033STB at 1896 AH.
 
Have any of you had experience with either, or recommend another option?  

 
As always, I am extremely grateful to all of you for the limitless wisdom offered.

Sinceerly,  

 
William Miller
