6 volt batteries

I know this topic has been covered many times however I wanted a different take on it. I would like to know if you're on a budget, what 6-volt deep cycle house batteries would you recommend. Please expand on it by adding how long they lasted you. Thanks to you all and Happy Holidays..

X2, I had a pair of these on our TT for several years of dry camping and served us well. They are made by Johnson Controls one of the leading manufacturers of quality batteries.

My first set of Sams Club GC2, 6 volt batteries lasted about 5 years before they were down to about 50% capacity.

3 of the years were full time off grid and the last 2 were winters only off grid, while being stored in the summer.

This was on my cruising boat, that rarely spent any time at a dock with power. Most nights we anchored out.

We had a residential fridge, satellite TV, and many comforts of home.

They still worked, but didn't last as long before needing charging. We are on our second set, but the boat is still on land since the storms tore up our FL Keys cruising area.

We have a pair of the same batteries in our MH since spring of 2014 and they are going strong.

We are on our second set of Costco batteries. The first set lasted 6 years. The battery bank is 4 6volt batteries. One of the batteries fail. I disconnected the bad battery and its mate and used the battery bank for another couple of months until I replace all 4. I only "Equalized" them a couple of time in the 6 years of service. I should have done it more as that may have extended the life. I did check the water in them every 2-3 months and never let them run dry. I was please with the performance.

If on a budget and you have a SAM's club membership. GO THERE
Costco is #2 again if you have a mambership

I went with DEKA from a DEKA store because once I paid for the membership.. Well the savings would not add up.. And would be eaten up by the added millage.

If no Sam's or Costco, DEKA or Interstate

Home is where I park it!

They are pretty much all private labels of the same or equivalent batteries, so just shop for price. Deka is an exception - it's the house brand for East Penn, a major battery manufacturer. US Battery & East Penn probably make almost all the 6v GC2 batteries you are likely to find at retail stores (including the Interstate label).

Just be careful to compare the Amp-hour capacity and that the quote is based on the standard 20-hour rate. A GC2 size battery is typically between 210 and 230 AH and going price is around $90-$100 at discount outlets. However, I've seen some advertised that turn out to be as low as 150 AH. If you see one claiming more than 230 AH, it is probably based on some non-standard rating or the battery is a taller size than the GC2 standard. Taller is fine if you have the room for it.
