What is the difference between the Optima red top and a Gel cell battery.

The Optima red top, 6v or 12v pictured is absorbent glass mat battery, or AGM. The lead plates sandwiched in the glass mat, and sealed in cylinders to contain the electrolyte. Mount in any position, and no evaporation or adding of water as with a std. lead acid car battery.


Gel cells differ as the electrolyte is mixed in a silica slurry.


Gel Battery Cons:
Lower output and can't handle as much current as AGM batteries, taking longer to recharge.
More expensive than AGM batteries.
Don't offer the same power capacity as AGM batteries of the same size.
More sensitive to overcharging, which can cause irreversible damage and shorten lifespan.



Great battery for the starter equipped T. 800 Cold Cranking Amps!
