I have an AGM (absorbed glass mat) battery. Comparable price to wet cell batteries if you shop right. Sealed, no maintenance, no tube. Lasted me about 3.5 years so far. Downside, unlike traditional wet cell batteries, is that when it dies, it dies with little to no warning. There are lithium batteries for close to twice the price. Light, but some say they don't have a good life span.
AGM versus traditional.
Advantages Spill-proof through acid encapsulation in matting technology High specific power, low internal resistance, responsive to load Up to 5 times faster charge than with flooded technology Better cycle life than with flooded systems Water retention (oxygen and hydrogen combine to produce water) Vibration resistance due to sandwich construction Stands up well to cold temperature Less prone to sulfation if not regularly topping charged
Limitations Higher manufacturing cost than flooded (but cheaper than gel) Sensitive to overcharging (gel has tighter tolerances than AGM) Capacity has gradual decline (gel has a performance dome) Low specific energy Must be stored in charged condition (less critical than flooded) Not environmentally friendly (has less electrolyte and lead than flooded)
