I am getting ready to replace my six (6) group 27 ships batteries and wonder if group 31 or 6 volt batteries are a better way to go. thanks Tom

Tom & Joyce:
I would look at DEKA AGM GP 31 and replace my 27s with these. They are nearly exactly the same size but 6 lbs heavier. They will give you 105 Ahr vs 92 Ahrs for the 27. You can get these Deka batteries shipped anywhere for free from tristatebattery.com/

Also, you can read all about these batteries from the Deka East Penn plant here:

So, YES...go with GP 31 and they should fit the same place your 27 are!

Here is screen capture of the key data, but see the PDF above for more.

Also found this link: www.eastpennmanufacturing.com/applications/marine/. I am thinking of going with Lifeline GPL-31xt AGM's for my next upgrade. Any issues ? reasons not to? For some reason my boat does not have a dedicated starting battery but apparently lifeline and deka has enough CCA to support that in a one bank configuration. lifelinebatteries.com/products/marine-batteries/gpl-31xt/
