Right, but OPtima sure likes to come up under gel batt search.
Is this a gel cell, or a sealed lead acid, or AGM ?
Wet cell is lead acid. AGM is lead acid. Gell is lead acid.
Wet cell has free liquid electrolyte. Caps are open to the air.
AGM has liquid electrolyte but it is all contained in a sponge like matting between the plates. Caps are sealed with a valve. So it is also a Valve Regulated Sealed Lead Acid battery.
Gell has a semi-solid electrolyte the consistancy of jello or pudding. Caps are also sealed with a valve. So Gell is also a Valve Regulated Sealed Lead Acid battery.
Some wet cells are considered sealed because there is no access but you better keep them upright to avoid a mess.
Optima is AGM only but is also designated VRLA similar to Gell.
Forget Battery Mart for info. Go to OEM webpage or batteryuniversity.com
