Using lift blocks on a 5th wheel

Break away setup questions

My first set of Trojan Golf car batteries lasted nearly 10 years - thought they were bad, got new Exide GC batteries, only to find it was my various crimped-on connections that were bad, NOT the original batteries... Gave the Trojans to my dad for their RV - still functionng now after 15 years as far as I know...



They REALLY hold up well!
 
I keep hearing the same story over and over, the golf cart batteries just keep going for years. You have to keep an eye on the water level but other than that they are practically maintenance free. Finding a battery box for them is a hassle but there are a few around.
 
I just returned from the Quartzite and Yuma, AZ areas, the Flea Market Solar stores were selling Trojan T-105 deep cycle batteries for $65. 00 each. No sales tax or recycling taxes.
 
I'll be in the market for new batteries for our 5th wheel this spring and until now I was going to replace them with the typical deep cycle RV batteries. Just how big are the 6volt batteries so that I can see if I have enough space? Thanks ---Cliff
 
I took two Trojan 6 volt batteries off my old trailer in '98. The old trailer had 4 six volts on it and I sold it with two. I ordered my new trailer without batteries. I put a new box on that would fit the 6 volt Trojans (cost more than one battery). I still have the same battery's on board (the plastic box is deteriorating). I have to fill them very regularly with water. I leave them installed in the winter, simply charge them every month or so. I imagine this year or next they will fail. At that point I will install four of them in new boxes, this will require simple angle iron installation on the front of the frame. For the money invested, it is hard to beat the 6 volt Trojans ($63-$67 apiece). I like the idea of Ken's floor machine batteries but the size difference in mounting them may make the difference (cost as well?).



I have three large solar panels on the roof and they seem to work well with two six volts. I have spent seven days dry camping in the summer with fans running all day and TV at news time at night. We have been in the heat in Chauko (sp?) canyon with three fantastic fans running (low speed) all day long for three days. The solar panels will almost reach 10 amps on a bright day. I think the 6 volt Trojans are the best bang for the buck as long as you have the ability to keep the water at an appropriate level in the battery.

For the size of the Trojan batteries go to-

On the T-105's, they have stopped putting the wingnut stud in the top of the normal clamp on terminal. It is now on the side of the clamp on terminal which lowers the overall height about 1/2". It is called a "low profile" T-105.



Also do a search for Exide etc for their battery information.
 
Here are the dimensions and weights for three batteries:



------------T-105-----------G27-------------G24



L----------10 3/8----------11 1/4----------12 3/4

H----------10 7/8----------9 3/4------------9 3/4

W---------10 7/8----------6 3/4------------6 3/4

lbs---------62---------------47---------------55

25A-------447-------------140--------------175

My battery dealer has plastic boxes that are made specifically for two T-105 batteries.
