Maintenance free batteries have no filler caps and you do not need to check the level nor add distilled water.
one is dry one is wet... wet once are used for car batteries and dry lead acid batteries the once you put in your remote lets say. I think the dry lead acid battery is maintenance-free and sealed batteries, and the wet batteries is the traditional batteries which needs more maintenance.
Maintenance free means just what the names implies. You will not need to add water to this battery ever.
Because there is no need to add water as they are maintenance free for life.
"Maintenance Free" BatteriesIn theory, maintenance free batteries are supposedly designed so as not to loose the water in the electrolyte, and thus not require that the vehicle operator regularly "pull" the cell cover plugs and add water.I personally have never "trusted" them and do not buy/use maintenance free batteries.
if its a maintenance free battery clean the terminals make sure its strapped down If not maintenance free, check the electrolyte level and top off with distilled water.
A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed battery or maintenance free battery, is a type of lead-acid rechargeable battery. Gel Cell, Absorbed Glass Mat (AGM), and Wet Cell are various versions of lead acid batteries. The Wet comes in two styles: serviceable, and maintenance free. Gel Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium Wet Cell battery.
High speed computers, RFID chips, xenon bulbs, maintenance-free batteries
Most likely no. Automotive batteries are generally maintenance free and the water level is sealed.
Lead-acid batteries have. The cap is not only a 'vent' to release gas during charging, but also a means of adding water to a cell when the plates aren't totally submerged.
