Battery recommendation
Hi, what are the latest recommendations for a good deep cycle battery for my trailer? I want wet flooded; not AGM. In a Group 24 size. I'll need two. My local RV shop recommends Interstate at $116 ...

WIRE DON'T GET IT
Correct wiring helps but is nowhere near good enough. I long ago lost count but marginally charged flooded batteries almost never test the same. Two batteries, same batch paralleled.
Sheesh. Use the noodle :)
Cells in SERIES become unbalanced. Cells in parallel are special?
This is why very few twin or more batteries seldom die together. One battery fails the other shows good numbers.
Top charging minimizes this nonsense and this nonsense is almost universal and top charging RADICALLY improves the equality of lifespan. This was found through testing and verification not, E=MC2
For my own system on Quicksilver, I let the 400-amp Niehoff alternator take the (4) L-16's as high as possible. Then that night is CONSERVATION NIGHT. A bare minimum of battery use. The next day the 4 Kyocera panels bring the batteries up to 15.0 volts.
I am the whipped rower on this slave galley. It's the batteries that demand to be satisfied. With more solar I could get 316 x 2 / 5% true optimum Top Charge rate with the Kyoceras. This would minimize conservation night. When I camp alone my engine is started at 0400 for three hours with the voltage regulator set to 15.0 volts.
Is it worth it? Fourteen years on the L-16's and 22 years on the 2-volt cells seem to suggest I am not in error. Neither is having a MEXICAN car battery last seven years. Thirty thousand dollars is worth paying attention to.
