Battery question,opinions?

In a nutshell, havent used the TC this season recently. I have 2 AGM batteries installed at the start of the 2009 season. Also a 128 watt solar panel. Looks like I might need to make an emergency trip to Florida after Irma passes and am thinking the TC will be a huge help if the mobile home is unlivable. Everything in the TC is up to snuff, even , as far as I can tell , the batteries dispite their age. To test I unplugged 2 days ago ,and had the fridge running. After 2 cloudy days they showed 12.5 in the dark. I ran the Fantastic Fan and lights for 25 minutes and showed 12.3 which bumped up to 12.4 after killing the fan and lights. Think they're OK for at least this trip? Im trying to minimize expense due to uncertainty of Irma's cost , but if it turns out I need batteries Im not going to be able to buy anything in most of Florida and likely anywhere South.
Just looking for input, the rational side of my brain is overloaded watching weather models on the TV. Im thinking they might be OK but then I've been really working at positive thinking this week and may be mistaken. So, thumbs up or down on battery replacement?
  • With a built in generator and solar and being that you really won't have much of a draw on the batteries for hogs like heat you should be fine. A test before is a good thing but even if they are not 100% I would not worry.

    From my emergency training side of things....
    - Toss in some extra fuel as if power is down you will need it and if it is not down chances are the prices will be up.
    - Take a good extension cord with you as if it is as bad as they say you will be the power company in your neighborhood maybe for a long while!
    - Another thing to toss in is a can of flat repair, going into a disaster area you will not believe the nails and sharp objects and just when all the shops are closed!
    - Top up your water and maybe carry extra with you. Those stupid collapsible water jugs (the ones that leak if the are not upright) are great as you can fill up before you hit the bad area and if not needed they fold down and take up very little space!

    Drive safe and all the best!!
  • Looks like I need new batteries, unplugged I dropped to 11.4 . Do I have this right?..... I want Deep Cycle Marine? Or any Deep Cycle? The comparison # Im interested in is amp hours? Whats MCA?
    West Marine has 105 amp hour in AGM and regular , Deep Cycle group 31 at 310 for AGM and 250 for regular. Costco has them cheaper ,have to visit to get #s.
    The final outcome was the worst scenario possible. Direct hit with at least 5' storm surge and 130mph winds. This on Bg Pine Key. Doesn't sound good at all.
  • MCA=Marine Cranking Amps

    You don't want a battery defined by cranking amps
    You want a Battery defined by Amp. Hours

    If you have to money go for a AGM battery or better
