are you saying that the maintainence free lead acid ones last the same ammount as the flooded batteries??
Yes, a flooded lead acid and a maintenance free lead acid are same - however you may get little better life due to the fact that battery will not die or degrade due to lack of water which you can easily forget to add in case of a flooded lead acid battery.
[Edit] A sealed lead acid battery AKA VRLA battery has some advantages like it can be fitted in any position, ventilation requirements are not as strict as for flooded batteries, no fumes or gases.
On the other hand, due to the calcium added to the plates (to reduce water losses), sealed batteries charge much slower than flooded batteries, they can not tolerate over-charging and will fail prematurely. They are more sensitive to high temperatures and may damage quickly in case of abusive charging.
