Sealed lead-acid batteries

I''ve seen some of these at a trade show recently. any thoughts on their suitability for marine use?

Sealed lead-acid batteries

but are those gel? the ones i''m talking about are lead-acid - more bang for the buck but in their former incarnation neither maintenance free nor completely safe (they exhale hydrogen - ok if you have proper ventilation). The guy I talked to said there''s a small pump inside that periodically expels the h2 - he said maintenance-free lifetime would be 3-8 years depending on the battery and the application.

alot of these batteries will be distroyed if the charge voltage goes over 14 volts. it will cause them to boil and vent. so be very coutiouse.

yes these are plain old delco lead acid batteries. I believe as does the boat manufacturer that you get the most bang for the buck with these. They are also available anywhere in the world.
my batery locker is sealed and vented to the outside.
