Time to replace the 12v battery in my enclosed trailer.  Won't hold a charge.  What's everyone using in theirs?

 
FWIW, Ive used 24 Group Optima's in mine for years.  the last 2 were brand new Blue Tops (3 years ago) that I bought on Optima's site, previously they were old Yellow Tops out of my Chevelle.

Look at US Battery. When I went to replace my RV 6V house battery’s I went over to Viking Battery in Santee. They’ve   been around for a long time. He turned me on to US Battery, and I have Zero complaints. Since I’ve used them, I’ve had two others we camp with put them in their RV & Trailers and no issues.

If your in East County San Diego go to Viking battery in Santee. Their Good people! 

 
Ok, time for me to jump in here. I replaced a couple of NAPA 6v for some AGM sealed yadda yadda stuff. Paid a decent price and to my surprise, they don't last as long as the NAPA junk I had in there. I'm talking about the LED awning lights on all evening, charging couple phones here and there and the usual TV before nighty night but these AGM aren't holding up. What am I missing here? I did set my inverter to AGM charging for some sort of slower or was it faster charging, can't remember but it's set correctly. Now I'm wanting to go back to junk.

I've posted this a couple of times in the past. The lowest priced good batteries are 6v golf cart batteries, like US Battery or Trojan, but NOT Costco batteries.

The best value for no maintenance, 10 - 20 yr lifetime batteries is LFP batteries.

All other deep cycle, AGM, etc batteries are over rated and generally speaking, the higher priced they are, the lower they perform. Here is a video of actual testing, if you care to see the technical details.

Funny you mentioned Trojan battery’s as I was a believer of them and have had two sets in my RV ownership lifetime. Then when I needed to replace them the second set, that’s when I was introduced to the US Battery. The owners of Viking are Trojan dealers and they had told me, I will not get the the same life out of new Trojans as my old ones. He said unfortunately they are riding on their name as the quality is not the same. The US Batteries were a little cheaper then Trojan, but he said the quality was better. So I took a chance. 
 

So far I’m on my 4th soon to be 5th year this season with no problems. But I keep my RV plug in most of the time and I check the water a few times a year or before a big trip. I think maintenance is a big part of longevity.

I didn't know about the decline in Trojan quality, that's good to know!

Any particular brand?  What voltage?  6v or 12V?  Where is the best place to purchase?
