I have cooked my 5er batteries. No water left it smelt bad thought out the coach.What's the chance they will be any good now? If not what is a good battery to buy.:help:
Cheers Den.

dont waist your time trying to bring the old battery,s back. i run twin deep cycles they work fine... have had good luck with exide and interstate batts, over the years.

I would not bother with the cooked batteries either. You might get them to kind of work, but their capacity will not be anything close to what it was. I usually get cosmetic defect ones from the exide plant down the road. Good batteries.

If you belong to Costco, give their Kirkland deep cycles a try. I just replaced my TT batteries with a set of them-$52 ea for the group 24 size...

I own a toyhauler, and do not have the luxury to be hooked to shore power, since there is none out in the middle of the freekin desert.

anyway, I just got 2 costco golf cart batteries @ 62.99 each, and hooked them up in series. They have the ablility to be charged and drained many times more than the 12 deep cycle batteries.

I know several people who have the same setup, and going on 3, 4, even 5 years with the same batteries.

I had all the lights on, including the outside floods, stereo cranked, inverter running tv and dvd for like 6 hours last night, not one dent in them.

that is my .02

Cart batteries are the only way to go.

Richard, are those batts something that all costcos stock? I am also looking for new batts for my trailer. Thanks

Ditto.
I use two Trojan T105's in my 5ver, two wired in series. Paid $62 each. You should be able to find them at a golf cart sales or repair shop.

These batteries are taller than a typical starting battery, so the common battery box is not tall enough. I moved my batteries to the front storage compartment, and mounted them in one of these battery boxes. Think I paid about $70 for the box.

The box makes mounting easy, and if the batteries leak, the plastic box will catch and retain the acid.

I called Inerstate Battries today the guy said that should not have this soon 14mths old .It sounds like the 5er is over charging.May be a new converter.
Den.

I've found through previous vehicles and my '05 Duramax that Optimas the only way to go. You end up shelling out more cash but for a deep cycle dry battery that never drains, whether your running a winch, aux lights, and aftermarket radio its the only way to go.

That water level can drop fast, I noticed that both batteries are low on my TT after just a months use. FWIW, I have brought back 2 batteries from the grave by charging them with a Battery Tender brand charger. Do a search for Battery Tender they are easy to find on-line.

My tractor battery wouldn't take a charge and I was tired of jumping it with the truck every time. Over the winter I took the battery in and left it on the charger for a month. (It is a battery maintainer) Then stuck it back in the tractor and it's been running fine for 2 years since.

I am not sure on that, but you can find other 6v batteries other than the costco ones, like the trojans... they have the 105, 115, and the 125

just remember to get 2 and hook them up in series to get 12 v.

i guess I was lucky. the costco 6v's fit in my group 24 boxes that came with my toy hauler

If you charged them dry they are toast...Heat warps the cells.
I like the "Exide Stowaway's", best bang for the buck I have found.

How can you determine how many times you can charge the 6v batts? On the RV.NET forum, this topic (6v vs 12v) discussion has been covered by guys who advocate both setups. Three factors seem to be drivers on this topic: (1) 6v batts will take more charges than 12v; (2) 12v batts will give you more AH; and (3) With 6v batts if one goes bad your out of business, but not with the 12v. I run my TT with one Interstate Deep Cycle 12v and use battery charger to recharge it when I run the generator in morn and evening to run appliances (coffee/microwave/AC).

Thats a good question...The method I use is the time it takes the batteries to come up to full charge and how long they last when using them...Right now it takes about 4 to 5 hours to bring two of my 12 volt batteries up to 12.7 volts when charging off the coach converter running the generator, each battery will last about 24 hours if I am on the kids about not running every light in their room, (Thats in high elevations with heater going most of the night and 5 showers)... When my batteries get to where they will not hold a charge for a day or take too long to charge I replace them. I have tried "optima" batteries and still use two for powering medical devices and the t.v. because I don't have to worry about leakage (I bring one inside)...But the "optima's" don't like high amperage chargers (They overheat and I have cooked one on a 20 amp charger). The best bang I have found for my buck are the "Exide Stowaway" wet cells, I bought a set 2 years ago and they are still going strong...:grd:

I'm very pleased using two Kirkland/Costco Group 27's for my 26' Sunnybrook TT. They'll easily do 4-5 nights running the furnace to keep the coach at 60-68 degrees in low 30 degree weather and handle all the other normal lights and water pump useage. But it's only 3 of us and we are pretty conservative/battery conscious.

I like to drain them down real good before recharging - usually at least 4 days before they need it. But I'd bet they'd get us through 6 day/nights if need be to push it.
