House battery "repair"?

Bought a new deep cycle battery at Walmart last April 2015. (29dc 845mca) Maxx

Installed & all was good. I left it in the camper all winter+ ( 7 months ) with shore power disconnected. The camper was outside all winter.

So- the battery is dead. I checked the water levels & it has water.

Is there a way to save this battery or because it was outside unplugged all winter it's a lost cause?

Tks,
CWT

    With a normal size solar of +200W, for maintenance charging it doesn't need to shine very often.

    Long absence was the main reason for me to buy AGM.

  • Try to charge it. Six years ago my two Interstate 6 volt batteries partially froze. They got slushy, not frozen solid. The sides were bulging slightly.

    I thawed them and put them on a charger. I'm still using them and the sides are still bulged.

    But, I will be replacing them soon. They're not holding a charge as long as they should. :(
  • It's probably lost, but can't hurt to try and charge it. Unless of course it's been frozen and the case is burst or bulging.
