- We honor the three year full replacement warranty! Amazon does not! Ask them!
- New batteries.
- We specialize in this battery size and have custom packaging for it.
- We will include five pages of instructions with four pictures on how to install this battery to replace a Panasonic or Miata battery. Just ask for it in the order comments.
Note: The picture is of a D51 the D51R has the terminals reversed.
This page is for the battery only without a Prius installation kit which you do not need if you have the Panasonic battery S55d23L, Toyota parts #28800-21190 in your 2001, 2002, or 2003 Prius just order this battery and ask for the upgrade instructions in the comments section of the order. We will include the instructions at no charge! If you do not have the original vent tube connector and tube (I have found then in the bottom of the battery well) you can get one from your dealer for about $10 or order on line.

What makes this a longer lasting battery?
The tightly wrapped spiral design (see cut away image toward bottom of page.) provides superior vibration resistance so you battery is less effected by pot holes, construction projects, drainage ditches speed bumps and rough roads.
Because of the spiral design the lead plates do not have to be strengthened with an alloy and are 99.99% pure. This results in lower voltage drop as the battery discharges and contributes to the longer life of this battery!
The three main contributors of premature battery failure are:
- Vibration which causes distortions in the plates and eventually shorts.
This battery is made by sandwiching the acid filled mat and the lead together and then tightly wrapping them in a spiral. This reduces vibration by 15X as a cause of battery failure.
- Repeated deep Discharges
This Yellow Top battery is also chemically configured to handle repeated deep discharges not huge starting currents.
- Heat! Yes batteries have less output when cold but they also last longer.
If you want a battery that lasts longer. This is it!
We offer free shipping on this battery via 1 business day for all of California and the metropolitan areas of Phoenix, Tucson, Flagstaff Reno and Las Vegas or Priority Mail to the rest of the 50 states Hawaii, Puerto Rico and other US territories! You should have your battery in 1 to 3 days!"

Comments from customers who have used this battery in the Prius for over a year!
"The battery has performed absolutely flawlessly and is one of the best improvements you can make to a Prius . Easy to install, everything is included.
In general, I am totally sold on Optima batteries; I use them for my cars and boat, my oldest one is about 10 years old and still works.
Toyota puts so much emphasis on how the Pruis main battery lasts the life of the car; but what they don't tell you is that the accessory battery is a cheap ass lead acid that, even in a best case scenario, will be dead after 5 years. The Optima should correct this issue and bring the accessory electrical system to the level of the rest of the car.
My factory battery died when one cell failed; the car was 1 year old at the time. As you know, Prius, with all its electronics does NOT have a simple circuit to shut down the interior light! It is therefore only a matter of time until one does not shut the door all the way and the next morning the battery is completely dead. This is what happened to me twice. When I charged the factory battery for the second time it failed. The symptoms were somewhat strange as it would still run but after sitting a few days it would not.
It is good to know that with the Optima kit the chances of recovery are much better . And I don't think I'll ever have to worry about having to replace it due to age.

"I just wanted to let you know that the Optima battery in my '04 Prius has been great. We had a few sub-zero mornings last week -- the kind that in the past, with the OEM battery, had me running a long extension cord and portable charger out to where my car is parked overnight to get it started. I had been taking to turning off the keyless entry system to try and avoid a cold-morning dead battery. I found the OEM battery to be the car's achilles heel, because when it is weak, you have to resort to the physical key to get in the car, and even then you can't get the back hatch open to access the battery.
But this winter with the Optima battery in place, not an issue. No matter the temperature, the car 'boots' properly, so all other systems, including the gas engine, start up without problem. I've always been a fan of Optima batteries, and adding one to my Prius brings up the 12V traditional electrics up to a quality level commensurate with the rest of the car.
Thanks for a great kit to install the battery."

"I've had no problems since I replaced the battery. The sound system sounds
great. I haven't let the battery discharge deeply (I've learned to turn off
the wireless key when I'm on vacation), but I trust the yellow optima is the
right battery for a deeper discharge and a good choice for this application."

From the manufacture:
The unique design of the SPIRALCELL TECHNOLOGY. provides many features not available in ordinary batteries. The following is a summary
SPIRALCELL TECHNOLOGY PROVIDES:
More plate surface, closer plate spacing, ability to use high purity lead. RESULTING IN: Low internal resistance. This low internal resistance gives you more power in a smaller box, ability to recharge much faster and higher cleaner voltage characteristics during discharge
Immobilised plates (locked in place). RESULTING IN: Improved vibration resistance, no shedding of active paste material, lower gradual loss of power and capacity as the battery ages. This gives you a battery that lasts longer and performs better throughout its life.

The Federal Magnuson-Moss Warranty Act of 1975 prohibits a manufacture from curtailing warranty coverage due to after market parts unless it can be demonstrated that they caused the problem. (For more information click here and scroll down go to paragraphs under "Tie-In Sales" Provisions.)
This sealed battery has little free liquid electrolyte because it is absorbed into the glass mat. Consequently, there is little acid that can spill into the trunk even if the case cracks. It also has attachments for a vent hose so any gases are vented outside of the car. The battery does not normally emit gases but can do so with heavy over charging with pressure building up and the valves in the batteries releasing.
