Product Description

Optima D51 YellowTop battery provides the extra performance and deep-cycling capability that your vehicle demands if it has a lot of accessories like running lights, high-performance stereo/AV system, winches, or hydraulics. The unique SpiralCell design provides a strong and clean power source, ensuring the safety of you, your family and the environment. The Optima battery is ideal for seasonal use because of its very low self-discharge rate. That means you can store your seasonal vehicles all winter without regular charging and still spring out of the starting block when winter is over.

Customer Reviews

Great replacement battery for Prius
I installed this battery in my 2005 Toyota Prius with the help of the adapter kit from E-learnaid after my OEM battery died. Aside from costing $75 less than the dealer battery it has a higher capacity and can handle the occasional deep discharge when I 'forget' to turn off one of the interior lights.

The battery was well packaged in a heavy cardboard box and arrived within a few days of my order. It took about 1 hour to replace as there are several components in the way that had to be removed. I would recommend this battery to anyone who needs to replace their stock Prius battery.

optama yellow top battery
used it to replace the battery in my 2001 toyota prius, works great and has much greater cap. than the stock battery did.
Required different adapters for the battery terminals hard to find.

Go juice and then some
There comes a time when you notice that turning the ignition key no longer launches the starter eagerly into action, but instead it reacts like asking your spouse to take out the garbage; it gets done but not without a flash of pained grimaces and a lethargic shuffle with shoulders stooped and an air of martyrdom. There's still some juice left in there but you know its past it's bloom of youth. If you don't want to find yourself pleading with passers-by with your jumper cables in hand one cold morning or waiting for the triple-A guy to show up hours later to help you get mobile again, you know it's time to replace your battery. Optima batteries have a reputation as the Clidesdales of the battery world, used in applications where reliability and extra power are needed; i.e., a car with lots of amplifiers in the sound system or extra fog lights or a power winch. (as in SUV or Jeep) Something to do with using 100% copper in the plates which are wound concentrically instead of laid out in a sandwich-like grid, which increases the surface area of exposed copper. (Thus the round cylinders visible in their body.) My car has a tight, high compression sports car engine and living in a hot climate means the air conditioner is engaged also all the time putting more strain for the battery to pull at start-up. When I push the start button now, my car literally snaps into action in a millisecond, there's so much extra power reserve. The dimensions are also smaller than the OEM battery so there's extra room in the engine bay for cooling air flow under there. From all I've read and my own experience, I highly recommend this to replace your OEM battery. As for your spouse, you'll just have to work things out or produce less garbage.
