    This Yellow Top lined up perfectly for my Mk4 Jetta VR6 and provides enough power for headlights and all powered accessories. No complaints.

    I have a 2008 Dodge Grand Caravan that has been modified for wheelchair use. Pushing the passenger sliding door button on the remote opens the door, slides a ramp out, and lowers the right rear quarter of the van so the ramp angle will be less steep. When it got frigid this winter, I would open the door, get in the van, close it up while I transferred out of the chair into the driver's seat, try to start the van and - you guessed it - not enough power left in the battery to turn the engine over. After the third time, I decided that I needed a new battery.

    I use this battery to power a forestry winch. It easily pulls down a half-dozen large oaks on a single charge and recharges all summer long with no problems. I only replaced the last one when a tree fell on it and cracked the case open. Even then, it continued to work fine and nothing appeared to leak out. They're pricey for sure, but when you've gotta have a good battery, they can't be beat.

    Batteries were trash... only lasted 3 months. Warranty/Return policy is garbage as well. They want me to ship the batteries from AZ to FL on my dime for them to "test and determine if they will be warrantied". Even if they send me 2 new ones, I am still out the $400 it would cost me to ship both batteries. I bought CAT batteries instead and they have lasted almost a year now on same truck.

    Fit just fine in my 2000 mustang GT battery holder. No modification needed. No clearance issues etc. I should have bought years ago.

    Our bus took two batteries so I used these. They are perfect for the extra electronics and to supply CCA for the diesel engine. I don't have to worry if I run them down because they are a combination of deep cycle and starting. They are also sealed so my terminals don't get that green dust of corrosion. The yellow top with the gray case is the one I purchased. These things are VERY VERY heavy but worth every lb! I also want a reliable battery when traveling and these can take the abuse.

    Very strong good battery, i did have one go dead on me but they replaced it and no issues since then. They are worth the hype and the money.

    The media could not be loaded. Espero una excelente calidad aún faltando le la entrada baja me refiero a la segunda imagen. La batería solo viene con los dos polos y eso es todo.

    I had an Interstate battery for 12 yrs, when it died I replaced it with 2 smaller I interstate batteries but with a total of more amp hrs. They didn't last 1 yr. but Interstate replaced them under warranty. That was good but the replacement ones didn't last any longer. I didn't bother returning them, didn't see any point to it. That's when I bought this one, installed it and haven't looked back. It's still working as good as day one. I use the battery for electrical lights and other things in my house, not in a car/boat.

    Couldn't hold a charge after 11 months. I bought it in January 21 and it stopped holding a charge by December 21. Waiting to see what warranty service is going to be like.
