    I've been looking at different batteries and more or less decided on an AGM which is very expensive but should I opt for a cheaper 'sealed' battery? I've got dual setting on my charger would a sealed until need to be set on Gel? I'm trying to avoid the venting type wet battery. It's all too much.... just to buy a battery!!

    no.. it's the same setting as a 'wet'

    whether you buy AGM or cheaper FLA (flooded lead acid) is up to you.. and your budget..
    personally I always buy cheap FLAs.. they may not have as long a life as an AGM but are lot cheaper to replace.. 'bang for buck' hard to beat

    If I were spending more on a battery it would be for a flooded deep cycle battery.. such as Trojan

    now you will get a dozen or more posts all with different opinions.. confusing , isn't it..

    You don't say what your usage is, if you spend a lot of time off grid a Gel would be a good choice as they can take an 80% DOD but they take twice as long to re-charge as a wet cell, AMG is a half way house the DOD is not quite as good as a Gel but better than a wet cell, a wet cell.
    If you go for a AGM most manufacturers recommend the Gel setting on the charger (check with battery manufacturer), however set to Gel the AGM battery will never quite reach a full charge, however in the Gel setting the charger holds the max voltage for longer so in practice it makes little difference.
    For example an Elektroblock charger in wet cell seting charges to 14.3v holds at 14.3 for 1hour then reduces to 13.8v, in Gel mode it charges to 14.3v holds at 14.3v for 8 hours then reduces to 13.8v. An AGM battery needs 14.8v to fully charges.

    I have two Victron 130 amp AGM deep cycle batteries and have my m/home charger set to gel and my solar controller set to sealed.
