great battery and a lot of starting power

December 20, 2010

I bought this battery 3 years ago and havent had any problems out of it. even in the coldest weather (-3) i can go out and it will start right up. i also use it during car shows to run my led underglow for 6 hr and it will still start like they were never on. plan to get another to run my tv and xbox. i highly recommend to anyone with car audio or needs a battery that is reliable in the winter time.

It's all I use. Anytime I get a new car, it get's a new optima yellow top. Works great for my system in my integra (also worked great on my system in my 4runner) and the lights don't dim. I'm sold.

My only complaint on the one I bought for my integra was that the battery posts were on the wrong side of the battery so I had to get a new negative wire to reach the post.

Amazing battery

September 14, 2009

This is the best battery that I ever know. I´m not going to talk about the power, reserve, the performance or if the battery can be discharged easily or not; I will say that on my entire life I never seen a battery with the capacity of being COMPLETELY charged only for the electrical system of any car, and this battery can do it! You can discharge all the battery when using, and two days later the battery charge it´s FULL, only for running the automobile. It´s amazing...

i had 2 of these batteries hooked up on my 03 ranger. my truck is bagged and uses 2 compressors and on top of that i had a rockford fosgate t40001bd amp that pushed over 4700 watts rms. i have a 200 amp alt that charged them. the 2 batteries held up and at the lowest would drop 2 11.7 volts when pushing the subs really hard. overall a good battery

just the battery any audiophile needs

June 1, 2010

When i start my car, it starts like its a brand new car. Also, before with my old battery, when I would just idle with the car on and tap the brakes, my headlight, dashboard lights, and any other light would dim, but not anymore since the performance of this battery, so 5 stars all around.
