Costco batteries

[northern]

Any one know about or have experience with
Kirkland (costco brand) 36 month prorated warranty deep cycle batteries.
I need to replace 10 six volt deep cycle house batteries.
Could go with five or more 12 volt ones if required

I only purchased the 12vdc one a few years back. I believe they were Kirkland brand. I had no problems with them and they were about 1/2 the price of what I was paying at Sears.

I have 4 x 6 volt Costco golf cart batteries for my invertor and they have worked great for the past 4 years....

Put three brand new kirklands in at the begining of last season, worked great.

Have a 12 v in the duck boat for 5 years, still work great. Also have two AGM (Kirtland) in the Ray.

Im going to be installing 4 6 volts for my inverter also , question , can i hook these in with my existing alternater ? can the alternator handle chargeing 2 12 volt and 4 6 volt batterys ?

It has been my experience that most batteries are made basically by the same companies and just re-branded. I'm guessing that is the case with the "Costco, Kirkland" brand.

I also have 2 Costco/Kirkland 6V for my house side since last year and have no complaints.

I had two costco batteries in the boat when I bought it last year they checked excellent on load tester, they were purchased 7/2011 had to replace both of them 2 months later. I went with the Interstate 27d from Sea Ray dealer 1 deep 1 starting only because of the warranty both lead acid the cost was 115.00 for starting 99.00 for deep. I would have used agm's but my old charger was lead acid only. You'll need to use a calculator to determine the size of alternator needed to charge your batteries depending on how you use your boat.
