"Finally something that gets me thought the day and I can carry from the boat that does not weigh a ton, I will update if things change. Will update after a year. 5/1/17 Ok bought a bigger boat with a older foot controlled trolling motor, the battery."

"Amazon is also the cheapest place I could find the optima batteries anywhere on line or even in any of the closest auto stores, so that's also a bonus!"
"I've had the battery for a couple months, no problems."
"Phenomenal batteries to use in a Honda Civic Hybrid."
"Well worth the money."
"3 optima battery for my cars and the first one is still going strong 10+ years, fyi use a good battery maintainer/charger if you havent charged it for awhile and this thing will last for along time."
"BATTERY WAS RECEIVED IN PERFECT CONDITIONS AND IT WAS VERY WELL PACKAGED IN A STURDY BOX WITH CARDBOARD INSERTS TO PREVENT DAMAGE OR ANY MOVEMENT OF THE BATTERY DURING SHIPPING. I have a scangauge II on my truck and I can monitor the voltage on real time on it and I have yet to see this battery fall below 13 volts running while playing LOUD music."
"Battery acid was everywhere and I was replacing the wet cell batteries every year. I have used that same old Red Top in two pick ups and one car, sold the cars but kept the battery for a spare cause it fits most applications and still starts most any car or pick up at 6 years old. Yea you'll need a deep cycle type maintenance free setting on your home battery charger, if you need to recharge Optima batteries. Wired in a Perko boat battery switch so I never have a dead battery. Yea you can do the same with wet cell batteries but they won't last as long and charge back up as easy as Optima batteries. Yes Optima batteries are about double the price of most replacement wet cell batteries, but well worth it."
"Turns out this battery was completely dead after 1.5 years in Minnesota."
