Last one I bought came from BPS last 3 years that I had it might still be going I sold the boat.
I take it that it was the BPS brand.
3 years is a good run for a marine battery imo.
I have an Interstate SRM-29 for cranking & accessories (pumps & electronics). Outboard is a Yammie 250 HPDI. I typically get 4yrs service out of them. Check water level couple times a year. Use SRM-27s on my TM.
Yep just the BPS brand I'm sure someone could tell you who the manufacturer is I never asked. Had to replace the trolling motor batteries so I went ahead and bought a starting battery while I was at it. The starting battery was still going strong when I sold the boat one of the trolling motor batteries had to be replaced about 6 months later. They swapped it out with no problems.
I found an 8A31 Intimidator "second" brand new on ebay for $150 free shipping. The "seconds" are always the ones I look for. Usually just cosmetic blemishes.
What kind of motor? Mercs require a huge battery.
250 Pro XB
'98 187 Elite, 175 EFI (Serial 0G750796)
Mercs dont require any bigger battery than the others!

The new 4 stroke merc requires 1000CCA as well.
700 CCA for a yami SHO.
675 CCA for a e-rude.

a lot of batteries issues, are operator head space.
For years and years I ran a 24 series Delco Remmy. I think it was 1000 cca. My supplier told me that I wouldn't have the same luck with the new Delcos ( Last time I replaced them was 2012).
I bought a NAPA commercial battery 31 series, it's a beast

Running the same battery for 5 years now and still going strong. Unfortunately they don't make them anymore, it's a Sears Platinum.
The sears platinum was made by Deka. You can find them at Sams under the Entergizer or Duracell brand...I can't remember. It's the same battery.
