The eight year old batteries in my 2015 R25 are in need of replacement and I was looking for recommendations for best brands, models, and type of battery. I have a two battery system with a selector switch.

And, you have to be careful with Lithium: Existing charging from alternator may not properly charge; may not have the crank amps needed to start the engine; can't charge in freezing weather; Need special chargers / maintainers. But, overall it may be less than running the needed wire from the back to the front of the boat!?!?Some swear by the Interstates that many originally come with. Tried and true flooded lead acid that tend to last several years or more with proper maintenance and relatively cheap. I've heard Wally World batts are decent. Trojan batteries are regarded in many circles as the best flooded lead if you want to up the budget but I only recall reading about guys using them for their trolling motors.
AGM batteries are also popular such as Optima and the X2 Power from batteries plus. I have no experience with either but a search of this forum or The Hull Truth will show lots of positive reviews.
The ultimate are Lithiums but you are going to want to really weight the pros and cons since these are so expensive. I personally can't justify them for my pontoon but if I had a bass or bay boat would seriously consider.
It came with 2 Interstate marine cranking batteries.....Do you prefer a deep cycle or starting type of battery?
I’ve always been pleased with marine starting batteries from Advance Auto. Looks like their marine batteries are DieHard now. Reviews look great, still.The eight year old batteries in my 2015 R25 are in need of replacement and I was looking for recommendations for best brands, models, and type of battery.

You've demonstrated to me time after time you know a lot about boats. What batteries do you run?Some swear by the Interstates that many originally come with.

Unfortunately, they weren’t available last year when I needed them.Here is what we dropped in when we had to replace our original batteries. They were what was specifically recommended by Mercury for our 200HP Mercury Verado Pro motor.

Lithium voids Yamaha warranty. I asked dealer to get them.
No idea about others.
Those are what came with my 2021 Benny!Here is what we dropped in when we had to replace our original batteries. They were what was specifically recommended by Mercury for our 200HP Mercury Verado Pro motor.
