Battery replacement

Looking for advice, please. Just returned a 10 month old size 24 Dual Purpose Exide battery to BJs as it would not hold a charge on my 2004 Sunny 2475. Converter (6000XL) putting out 13+ volts. Battery dropped 4 volts in 12 hours with only the fridge running on propane. Check light comes on for fridge and HW heater won't ignite. Status indicator on panel drops from full charge to one bar. Any recommendations for a replacement? Stay at 24 DP? Move up to 27DP? Go to something else? Best place to purchase? Don't boondock very often and have a generator when I do. Also not looking to spend a fortune. Thanks in advance.

Batteries have become ridiculously expensive all the little control circuits don't draw a lot of power but lights, pumps, fans and furnaces do. So if you generally plugged in or run the generator the smaller battery should be fine. I would say pretty much where ever you go your looking at a $100 for a new one just make sure they have a good warranty policy and make sure it is a deep cycle the best way to tell they will have posts that have screw threads a long with normal battery posts. I would stay away from a starting/deep cycle type just a good deep cycle a group 24 is generally in the 80-90 amp range.

That was also my thought about staying away from start/deep cycle. It seems that is all the auto stores here have in stock. Where can I get a primary deep cycle battery without going to 6 volt cart batteries? Should I just go online?

Walmart for one. Marine deep cycle. Marine stores and of course RV. Possibly Home Depot will have. Tractor Supply have deep cycle batteries. Be carefully there as they also have the dual purpose battery also.

Check the listing in your area for battery dealers independent shops that sell batteries they would be your best bet they know batteries. Walmart all though I refuse to grace their door does have a good return /warranty policy on their batteries bottom line there is only about 3 companies that make batteries and dozens that re brand them.

I have worked for 2 mom and pop dealers since I started in RV repair business and the only battery they would sell were Interstate HD24-DP and SRM-24. Except in the year 2007, I have had no problems with there batteries and I use one myself. There warranty is also solid. I usually do not push products. With these I do.

Thanks everyone for your input. I found out that Sam's Club sells a 12 volt golf cart deep cycle battery (GC-12) for around $200. I think I am leaning in that direction.

It is a battery that needs to be looked after. You will need to check it and add water as needed it's not a maintenance free battery plenty of amps though worth the effort.

In theory you could use two 6 volt batteries in series. However, you'll have double the weight and most likely double the cost, not to mention mounting, space could be an issue. They will work but possibly not practical.


The purpose of deep cycle to protect that battery if it drains too low. If a regular car battery drains too low you could actually end up damaging the battery. For using them in a trailer, I think also they should be fine for those rainy nights you're stuck in the trailer playing cards, no electric power and you're depending on the batteries alone.
Some one else here may agree or disagree. If so, please correct my thinking. I have two liquid lead acid but I was always curious about going to AGM or deep cycle for that reason alone.

Discharge/charge cycles in start batteries will kill them pretty quick they are short term high current where as a deep cycle will take many discharge cycles and provide a longer draw down of power. AGM batteries are a good choice but they are expensive.

I see Wal-Mart has the B-1000 and B-2200 stand-by batteries for use with sump pumps. Are these the same as a deep cycle cart battery? They are way less expensive.

Very good question I could not find any amp hour rating just says how long it will run a pump kind of nebulas with out saying how big the pump is . If they are a lot cheaper there must be a reason. 45# is a good weight meaning it probably has a fair amount of plates for it's size but it sure would be nice to see figures.

In researching more, it seems standby batteries are designed for about 5-10 deep cycle charges per year. Marine deep cycles are designed for hundreds of cycles per year. The gc-12 (12 volt golf cart battery) from Sam's Club was too big and too heavy at 90+ lbs. Also was $200. Went with a Duracell Marine deep cycle from Batteries+ for around $90. Fyi, have them fully charge the battery first. Took mine home and went to top it off with my Tender Jr. Store said maybe a few hours. 24 hours later, still charging. Took battery back and was told maybe charger bad. Bought a new one. 6 hours later, still charging. Back to store. Manager said he would put it on his charger. Took another 6 hours, much to his surprise. Manager apologized and said he learned something. He did not realize his batteries were delivered in such a low state of charge. All good now. Also returned new charger, since mine is working perfectly

I tend to argue with people that claim my equipment is broken. Learned from internet technical support that service tecs first answer is to question areas they are not responsible for. I reset my internet settings many times when the problem was their modem or other hardware. shame on them. Now I Make them check their equipment before I make a change to mine. Good you have a good battery.
