The Optima batteries carry a price premium because of their design, however their long life and ability to work in any orientation and in rough environments is what you are buying. Additionally, you do not need to worry about acid spilling out like you would with traidtional deep cycle marine batteries. Cost, however, is substantially higher.I ordered mine through amazon and it was shipped ground from their fullfulment center in Sacramento nearest to me in the bay area which meant it arrived overnight. I was a little disappointed at first getting ground service as a prime member, but overnight beats 2 days and their fullfillment centers are across the usa so chances are you will get yours in 1-2 days by ground ups. I have used Optima batteries since I killed my first battery in my H1 humvee offroad in Alaska doing 60 MPH over rock roads from the Yukon territories to Alaska. Ordinary car batteries just don't do well to the vibrations the H1 hummer can...

Optima batteries are one of the best on the market. I am very impressed by their longevity and high power delivery. I have had a yellow top Optima in my 4wd truck for 9 years now and it is as strong as the day I installed it. Other great features of Optima batteries are the facts that you never have to add water, they can be mounted in most any position and the terminals never corrode.This purchase was a second blue top D31M. I use two of these batteries in parallel to power a 2000 watt inverter. I tested it by placing a 1500 watt load on the inverter which drew 137.5 amps from the two batteries in parallel. They were able to sustain this load for 27 minutes. That is like cranking a 6 cylinder engine for half an hour. I previously used marine deep-cycle flooded-cell batteries for my inverter but they would only last about two years and I constantly had to check and add water as well as clean corrosion from the terminals. The bottom line is even though you pay more...

Over the past 5 years I have purchased 3 Optima batteries. The first one lasted just past it's warranty date and then failed. It was a red top. The last two were very expensive blue top marine deep cycle/starting batteries purchased at the same time and put in the same boat. The batteries operated through a Perko switch set on ALL. They charged together and discharged together. They are just now 37 months old. One has failed completly and the other still works. The warranty is 18 month free replacement and 18 month prorated. So here again no warranty help.Most battries that you purchase for $200+ have a 48 or 60 month warranty. Optima does not. The company would go out of business if it had to honor warranties that other battery manufactures offer. Optima is just a lot of hype. I have learned my lesson and will never purchase another Optima battery. Optima is owned by Johnson Controls and moved their manufacturing plant to Mexico. In Mexico they are not... Read more |
