"Two days ago my battery died and I started charging it. Better off buying a Interstate battery with an actual warranty.. ****UPDATE****. After writing amazon absolutely furious the original battery died on me after less than 90 days. Result even though I got a defected battery Amazon fixed the issue in a timely manner."
"Simple explanation: The battery ships with a thick plastic shield over the posts. If your battery mounts by a clamp on the bottom lip; you don't care about the height."
"The battery arrived well protected in its own box with blocks of Styrofoam to keep it in place."
"First let me start off by saying that I am fairly impressed with the performance of all of the other Optima batteries I've bought and I understand that sometimes there are glitches in manufacture that will produce a dud every once in a while."
"It is probably the best battery so far I have bought."
"I've been replacing batteries after 3 years and hopefully this brand will last a lot longer the my previous ones."
"This battery has a shorter profile than my old battery."
"Amazing battery."

Reviews
"This one does which seems like a no brainer, but in the era of "not enough dollars = not enough sense" in manufacturing you have to be careful. So far, it's doing it's job, battery is holding it's voltage just as if it was disconnected."
"Sometimes I may leave it sitting for extended periods of time, and the radio was draining the battery. You will need to get a short heavy duty cable to run from your battery to the switch, and obviously a place to mount thing thing."
"The power cables leading to the switch were not long enough to cut and replace with larger eyelets so having 5/16 threaded studs was my most practical option or to perform a rather difficult re-wiring job."
"Installation was simple and the switch works just fine, as intended."
"I have a lot of extras in my car ( MSD Ignition, Amplifier and 2-10" Bazookas, capassitor, high performance fuel pump and a few others."
"This switch allows me to kill the battery and charge it away from the RV converter/charger."
"Excellent quality and worth the higher price!"
"All the other parts were bagged up and heat sealed except one of the baggies had 4 washers, 4 nuts but only 3 bolts."
