What battery on SN 2004?

This happens every 3 or 4 years. Any recommendations for battery choice for a 2004 S/N? The battery well is very shallow so only a few will work. Thanks.

I take the old one to Costco and get one that's the same size.  In my experience it's not a marine battery, just a typical automotive battery.  The marine ones don't fit.

I just take the old battery to Auto-Zone and get a replacement.

Just go to Walmart and get a type 24 battery. I also have a 2004 SN 196 with the Excalibur 330, got 8 years out of the last one. Only $100 back then.

If you have a Rural King nearby, their, their battery prices are hard to beat.

Just bought a battery at costco for our suburban - still  $100 after core trade in. Last one made it 7 yrs

Thanks to all. One more question. I seem to have voltage leak in the system somewhere. In northern Ohio, ski days can be few this time of year so the boat may sit idle for a week. I always turn off the main switch but still the battery goes dead. How can that be if that switch is turned off? Been fighting this problem for years. I know the easy solution is to just disconnect the battery but I really would like to figure this out. Thanks.

Bilge is generally directly to the battery and bypasses the main switch.  I don't remember which nautiques, but some had the bilge on a timer versus just a float, so after a while it could run down the battery (especially an older/weaker battery).
