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 produce. Additionally when offroading, the H1 may tip up to 40 degrees on sideslope which will spill the acid out of a normal car battery while the optima does not loose any acid or liquid at all.

You *MUST* match the color code of the optima battery with YOUR intended purpose as follows:

BLUE (this one) - DEEP CYCLE applications - RV's, inverters, UPS systems basically applications where you plan to drain the battery dry every time then recharge it pretty soon afterwards.

YELLOW (what I use in the H1 Hummer engine) - Has both deep cycle ability and engine starting ability. If you drain a NORMAL engine starting battery dead you take between 5-10 percent of its life away right there.

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 initially to buy an Optima battery the long life and power delivery quality actually make it cheaper than other batteries when you divide the cost by the number of years of service.

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 held to strict enviornmental laws and employ cheap labor. They now offer only a 24 month warranty, period. I guess they know how long their battery is good for.

Below is a copy of the email I got from Optima regarding a battery purchased from Amazon.
So be aware the the money you are thinking you are saving maybe costing you big time. You should also know that for marine batteries Otima is strongly reccomending the use of there $200 charger to keep them charged properly.

Hello John,

Amazon.com is not an authorize online OPTIMA retailer, We do not know where they acquire the OPTIMA batteries nor does Amazon.com honor the OPTIMA warranty.

I've bought nothing but Optima batteries for my boats since 2002 and used to love them. No servicing was required and they used to last more than five years, on average, vs. one or two years for conventional batteries. Lately, I've had very bad luck with my AC Battery Charger on my boat (replaced it in Oct 09 and again in Feb 10). Once these batteries were discharged they never came back up.

Bought this on 3-09 realized it was bad when I summarized my boat 4-11, one month after the Warranty was out, started to notice it was going out last summer but thought it was sulfated and bought a ctek charger to take care of it in the winter. I had bought a walmart battery at the same time with a perco switch just in case and the walmart is still able to start my boat but the optima will not even crank the motor over! Called to optima and they were thrilled that the battery was just out of warranty and did not even want to help!! I got about 7 months out of this battery. I would have considered even giving them a chance if they would have at least prorated a new one since the battery has not been in use since October of last year, im 31 and have a lot of battery's to buy in my lifetime but it will not be an optima!!
