Rated 5 out of 5 by vlad Needed New Battery
Immediately after turning the ignition I felt the difference. I have a high powered audio system and at night with the headlights, ac and stereo on the headlights would dim. Not with this new battery! I know it costs a little more than the regular battery but well worth it! With

Purchased one of these RedTop back in 2006. Still starting like the first day. Simply unbelievable. Would definitely buy it again and recommend of course! Just 1 Optima RedTop outperform 3 or 4 times better than traditional batteries, in a row.

I recently replaced my optima after 9 years in Las Vegas Heat. All my vehicles have optimas now.

My car had a smaller battery than the manufacture recommended size. After installing this battery my car has been a breeze to star up.

Rated 5 out of 5 by CarGuy609 Super long life
These batteries are amazing - forget the warranty on normal batteries where they barely last to the end of warranty period. I have one of these in my truck that sits sometimes for weeks or months, battery is 7 years old and it starts every time. I recommend this for dependable starts when you have a vehicle that sits - or when you want it to outlast the warranty period. My Acura MDX OEM battery barely lasted 4 years - now it has a real battery!

I bought it to replace another lead acid wet cell fail. Picked Redtop up at one of the local Pep Boys stores and put it in myself. You have to install the adapter that comes with it so you can use your original clamp setup but went in no problem.
So far so good. It has been a trouble free month but long term will decide if it was worth it or not. If it doesn't go bad in 16 to 18 months and crud the terminals then it is a win!
