Battery charger recommendations

I use a smart relay. It is normally open, if it senses 13.5 volts on either battery it will close. This shouldn't be an issue. For me it is a small issue. I run a small solar panel on the AUX battery, when the aux battery is full charge the solar panel puts out 13.5v and I hear the relay close, the voltage drops the relay opens. I Have to disconnect the solar panel at times.
 
If I remember from my golf cart battery hunting days, odyssey made very good deep cycle batteries. They are now owned by enersys, but while enersys has a portfolio of battery brands under it, Odyssey is the only one Ive heard of. (PowerSafe, DataSafe, Hawker, Genesis, Odyssey, Cyclon, IRONCLAD, General Battery, Fiamm Motive Power, Oldham, Express and NexSys)
 
I like Odyssey, use some in our fleet. We used a ton of Optima's, if the Optima was to small it got an Odyssey. Heavy batteries, apples to apples.

Side posts are far superior to top post with squeeze clamps.

Everything should switch to top post studs, like semi tractors.

I agree with @1-ton on the side post batteries, I have had too many where the nut pulled out and ruined the battery and I even had recently one of my dual post batteries lose one of the studs, not really the batteries fault, it was a bad contact that melted the lead and got the bolt out.
I prefer the big rig batteries with a solid stud on top, easy access unlike the side post batteries.
 
Replaced the cracked terminal. Ground was still good, so I left it.

New $109 Oreillys battery.

Kept the optima still has some life. It's in the garage. I used an old battery I had on the side of the house for my core exchange..taped wires together so they don't flop.

Started up fine.

We put a dual battery kit with isolator in my brother’s Jeep. He running odyssey’s.
They’ve been great, but only a year old so far

Those look nifty... don't see why the clamp is any less effective.

They are a very good battery.... if you do not let them discharge. Once they do that, they're a 50 lb paperweight. There's almost no bringing them back at all.
 
Has anyone "reconditioned" a lead acid battery?

I am unsure how this escaped me before, but came across multiple articles on how to do it. Relatively simple, especially for the cost of batteries now.

Curious how it's turned out for anyone.

I have done a few lately.
A few years ago I bought some fluid that supposedly desulfates, but I didn't have any success.
Now I got a charger from noco that has a desulfating function and out of 8 batteries I fixed 5, they were all swollen and weren't taking a charge.
I had to go 2 rounds on some to get good enough but I am happy with what I got.
The ones that didn't come back had internal shorts and were overheating too much on charge and didn't get anything.
I am not sure if the fluid I used before would be beneficial with this charger, I might try this
 
The fluid you got is what you "rinse" the cells with? I've never attempted to take a lead acid battery apart, so this intrigues me.

No, you just added it to the acid.
I am not wil to go that far with a battery, I might if things get so ugly and there are no more batteries in the world and my life depends on it.
But not yet :D
 
Having never had a battery apart, I'm skeptical if it's as easy as the articles make it sound. But not much to lose on a battery that's already pretty well dead I suppose.

If it works, I figure maybe every five years you just do it, as preventive maintenance, and your battery may last a good long time then??

A good preventative non invasive thing is these chargers with repair functions.
Do the repair once a year and check for low acid levels and top off with distilled water.
That's the other thing that destroyed a couple of my batteries, they were overcharged in the truck and dried up and shorted out
 
I'm not sure I really buy the desulfating aspect of those maintainers. Is there actual evidence that they work? Not to argue, I just hadn't seen anything that showed results in testing.

Mine supposedly does that, we will see where my battery sits in a few years I guess.

Here is my charger. I stole from my old man, when he split, when I was 15yo.
I'm in my mid 50's, now. The only thing I've had to do to it, is replace the cord, with an old extension cord I had laying around, when I paid the stupid tax, by driving away with the thing still plugged in under the hood:doah:, 5 years ago
It still charges great like it always did. I bought some new clamps for it. I just have to find them...


I usually buy my batteries used from picknpull. They're $20, and I've never had one outright fail. I usually get atleast 2 years out of them, usually longer.
