Recommendation for replacement battery

[TxTiger]

First, anyone traveling this weekend I wish you a safe and fun trip.
My battery is going on 3 years old and doesn't seem to maintain a charge for very long so I'm going to replace it. Any advice on what type of battery to get (deep cycle, big cranking amps, etc) and brands that have worked well for you would be greatly appreciated. I see batteries listed as rv/marine, but some seem to be deep cycle, others with large cranking amps. I would think deep cycle would be better than something with a lot of cranking amps, or something with both. But looking for advice since I don't know.
Thanks

The weight thing is very nice.

I watched until they where on sale ordered two free shipping to local store.
They are five years old still hold charge well.

Are the terminals always corrosion free?

Glad to here that. Got the same thing now 2.5 years old. They are made but universal battery.

Sidecar, with a statement like that you just got 20 demerits in my merit book. I had more respect for you bud but now you'll be gathering firewood for the rest of time for all of us.

Trojan Batteries have a very good reputation and are expensive enough to have to be vigilant about taking care of them. Only reason I go cheaper ones is not having to worry about them so much, esp. when they have to stay uncharged due to circumstances while traveling..

I'm sorry. Was just injecting some humor. At my age, the only Trojan I use is a battery(s).

How is Trojan lately?...

I am on my 2nd Trojan. The first lasted a decade, and it wasn't really bad - I just felt like being proactive due to its age. Longevity attributed to annual watering with distilled water.

No complaints about Trojan. I am a happy customer. Trojan batteries are made for portable industrial equipment that draws a heavy power load. Think the floor cleaners that they run around Home Depot, etc. They are not marketed at RV owners as a primary customer base. There is only one supplier in the area (greater Portland, OR metro), although there are several dealers that buy from them. So they are not the consumer grade batteries you can expect to find at your local Wal-mart/Costco/etc. It takes some looking and calling to find out who has them.

Trojan batteries are worth the extra effort and expense in my opinion.

The condoms ain't bad either....lol

It was one model of Samsung that had battery problems and other models were fine. Samsung had multiple battery suppliers fail which resulted in pulling that model. Samsung is now reintroducing that model with its own manufactured batteries.

Okay now I'm understanding what you guys are talking about. DW thank you for the links and good reading. SidecarFlip thank you for your persistence I see now the advantages of Lithium iron type batteries.

I'll be staying with the wet cells for awhile till I see Lithium iron used more and more which may reveal any issues with their use and wait till the price comes down due to prevalence in the market.

Thank you Guys....:)

I don't have one (or more) at this point, but I will when my Trojans expire from old age and sulfation.

One thing I like about the solid state Lithium-Iron-Phosphate batteries is the weight. 26 pounds for a 100 AH battery versus 50+ for a conventional battery. I can install 2 at the same weight as one conventional battery and with me, I'm very attuned to weight.

1600 bucks is a lot of jack but with a 5 year guarantee, no memory and unlimited install positions, even 800 bucks a toss works out pretty well.

I think the fire risks may be just a bit blown out of proportion. I've heard many stories about lead acid batteries blowing up, but so far nobody is advocating not using them.

And you don't need an $800 charger.

That, they do, especially under high amperage boosting where they are producing lots of explosive gases. When jump starting a vehicle it's good practice to cover the battery with a cloth, clamp the positive terminal first and then the negative and don't smoke.

Lithium-Iron batteries charge with a conventional staged converter that you already have in your camper btw.

It's weird because there isn't anything on my google search that indicates any differentiation from Lithium Ion to Lithium Iron.

Probably because Lithium Iron is a subset of the group called Lithium Ion batteries where the Lithium Ions are what moves from the negative to positive electrodes. A Lithium Iron battery IS a Lithium Ion battery, but not all Lithium Ion batteries are Lithium Iron.

The lithium iron phosphate (LiFePO4) battery, also called LFP battery (with "LFP" standing for "lithium ferrophosphate"), is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO4 as a cathode material. LiFePO4 batteries have somewhat lower energy density than the more common lithium cobalt oxide (LiCoO2) design found in consumer electronics, but offer longer lifetimes, better power density (the rate that energy can be drawn from them) and are inherently safer. LiFePO4 is finding a number of roles in vehicle use and backup power.
