Producto correcto entregado en tiempo y forma

This battery is fantastic! It fits perfectly in my YJ Jeep, so installation was a breeze. I needed a more powerful battery to use with my winch and power converter, and this one has more than enough power at a great price.

a lot better than motomaster eliminator

Confirmed fit in 2001 Porsche 911 (996) 3.4L Coupe. This battery is the best battery you will get for your Porsche. Typically I get about 7 years out of the yellow top and most of us don't daily our 911s so a deep cycle battery like this one won't let you down. Deep cycle batteries are tough and Optima gel cell batteries resist vibration, which is the primary killer of a battery. My 996 tends to sip down electricity just sitting. Repeated draining of the battery will kill a standard battery , even a red top Optima... which are trash (IMO) but the yellow won't suffer nearly as bad as a standard battery. Car cranks nice and strong every time even if she sits for a week or two. Pro Tip - Mounting : This battery is NOT a direct fit to the battery box. Optima doesn't make a direct fit replacement battery for a Porsche 996 at the time of this post. A custom spacer is needed to lock down the battery so it doesn't move. Some people use a high density plastic, like a thick cutting board to fashion one. I used a 12mm or 13mm combo wrench as a spacer. It was the perfect size, shape and had the rigidity to do the job. I was able to really crank it down and the wrench had enough tension to act like a strong spring on the hold down tabs of the battery. This might sound like a "backyard fix". It works, and works great. I have had the battery in the Porsche for a year and 6,000 mi now. It has withstanded a lot of spirited driving , jars and bumps and still it's solid. Battery terminals are in the correct orientation and the Factory Porsche Battery cables are plenty long enough to reach.

Very much supply my gadgets (ham radio)
