    Default Used Interstate battery??

    We bought Interstate batteries for one of our inverters two years ago, and one has gone bad. Other three are fine. 

    Taking a shot in the dark here to see if anyone has a used one for sale. 

    Otherwise will head to LA Sirena for red Trojans, the ones we have on other inverter are older than these and still going strong.

    AE,
    The advice is never to mix old and new batteries.

    Replace all or none

    We had a whole big thread on this a while ago. ( one battery going bad the rest ok)
    again, IMHO a battery does not go"bad" in 2 years ..esp if the cells are kept wet..
    This sounds like a perfect opportunity to try to re condition it ... I would not throw away a 2 year old Deep Cycling Battery ,. no way.

    On a side note: I'll never ever buy Interstate again. I used to have red Trojans and only needed to fill once every two or three months. Then bought the more expensive interstates and need to fill every three weeks. Which I ofcourse forgot and they got dry and are ready to throw out (so yes I have (4) used interstates, but you shouldn't want them.

    I'm curious, what do Trojans cost in the DR.
    I just replaced four 12v Trojans in Texas for $871.00.

    I have NEVER heard of anything that will reliably recondition a deep cycle battery that has failed. Snake oil, promises and failure. If a deep cycle battery is cycled deeply too many times, it will indeed fail in two years. Even less time. There are charts on Trojan's web site that show how many cycles at certain depths before failure sets in. I have had my share of such failures and attempted resurrections.

    The warm temperatures in the DR are also a problem for batteries. Trojan T105 (reddish color) 225 AH batteries are about $150 US here at La Sirena. So far, the ones I have purchased at La Sirena have lasted longer than those purchased elsewhere.

    As far as replacing the one battery going bad with a still good but older one, it might help make the bank last, but it probably won't.

    Always wondered why people believe in reconditioning a battery here. But then again many Dominicans believe in zombies. So it's a gamble for you. Buy one new and maybe get some more time or spend a lot for all new batteries. You are between a rock and a hard place. Have your husband decide then when the one new battery does not work you can complain. That's what my wife would do.

    Good choice AE. Take a look on the Trojan website about "equalizing" your batteries to insure equal life from all batteries on the bank..
