New battery time, HELP !!

My house batteries (4-6V batteries) are a little over 3 years old. They don't hold a charge for very long anymore, so I guess it's time to change them. They are Interstate Deep Cycle batteries. Printed on the batteries are .........Interstate Deep Cycle Extreme GC2-XHD-UTL
122mins @75amp 232AH
Looking for suggestions on batteries to replace them. I can do the work myself. New Interstates are a about $160.00. Thanks

    The Interstate DEALER actually did not recommend Interstate 6 Vs, when I was shopping for them. I got Trojan T105s and they are very good. Of course you do have to pay attention to charging them correctly and not discharging them too far.

    You may want to look at Interstate AGM's. I just installed twonewcoach batteries and I'm very pleased.

    I have good luck with 6 volters from Costco, around $80 each.
    I also updated my converter with a newer model with Charge Wizard.

    Before replacing them, you may want put them on a portable "smart" charger & do a complete "equalization" charge. Also, use a temp. compensating hydrometer & check each cell prior to starting the charge & after completion. Check each cell & make sure the plates are at least covered with water, fill as needed, AFTER charging is complete.

    They may not need replacing at all, just "equalized"
