Not Long Lasting or Durable
"Purchased a D27 Yellow Top Battery for a 2010 Tacoma. Warranty was 3 years, but supposed to last much longer than a 36 month standard battery. At 3 years and 2 weeks, the battery quit, would not charge, would not deep-recharge using an AGM charger per MFG instructions, and no options from Optima. At $300 with tax, this battery is not worth the money and does not stand up to the claims. "
"Very good battery I ordered the yellowtop 75/25d and it came fresh only a couple days old. Floats at 13.0volts and it runs my car audio system very well. I haven't had any voltage drops since installing this battery. I will update to let you know how it lasts."
"I never got the batteries and I want my money back"
"parese me incredible that an almost perfect battery invented recommend all users"
"I was looking for a well designed battery to run my Electric motor on my 17 ft. Aquasport . It is powered by a 90 hp E-tec Evinrude outboard and I use two gel batteries to start it and run all my instruments. This Optimum battery will be my stand alone power source for my electric motor. I just installed it and it runs my motor very well. I hope it holds charge for my slow moving looking for cruising fish on saltwater flats."
"ARRIVED AS EXPECTED. JUST PERFECT."
"Great addition to my '65 T-Bird!"
"Love all of the optima products and the ordering process was wicked easy. Thank you for your products! "
"On time and what I ordered. On issues."
"I work for a scientific agency, and we use Optima batteries exclusively now for our field equipment. These things are indestructible, and just keep giving. We've had 6 of these batteries purchased here, and are adding to the collection. These will run (in pairs) all day charging capacitors which dump six-hundred amp pulses. After 3 years with those, I've not noticed any reduction in capacity. We've all changed our personal vehicle batteries to Optima now."
"Great product, easy to use, care free and added piece of mind that the battery maintains proper voltage."
"They had what I needed and got it to me quick "
"It came when it said it would. Great package. Very happy.????"
"Arrived on time works great"
"Great battery over any lead acid battery I have ever owned!"
