While I agree with most of what was said by Goody59, the only advantage a sealed battery has over a flooded one is no maintenance.

They are almost twice as expensive and for the same money you can get twice the AH in one that requires occasional service with distilled water.

For example Optima Batteries 8050-160 D31T YellowTop Dual Purpose Battery: Automotive is Dual Purpose battery and retails for 269 dollars (routinely discounted to about 220. It has an RC of 155 minutes.

To convert RC to AH How can I convert 25 amp Reserve Capacity to Amp Hours at a 25 amp discharge rate? | Discover Energy you multiply the RC by 0.4167 so the AH capacity of the yellow top is 64.59 AH.

The exact same size battery

Is a top of the line Dedicated house battery (deep discharge only with no car starting ability) Trojan Battery Company

yet has a 115 AH for the less money.
