  • Physical Size, Delivery and Installation
Product Packaging: Frustration-Free Packaging
I am rating this item with 5 stars due to the seller services (Timely Shipping) and the product installation flexibility and Miscellaneous Installation Adaptors which made it very easy to fit the battery in my 2008 Dodge Ram 2500 Cummins Battery Holder. It was a JOY..... I have seen many 5 start reviews of the performance. I have also heard many positive reviews. I will wait for a while to write any performance review for it. So far the engine starts PRETTY EASY. ... show more

  • Warranty is a lie, died after 6 months - could not be more disappointed
Product Packaging: Frustration-Free Packaging
Died withing 6 months, installed on a Factory Five Roadster with a battery disconnect, driven maybe 5X in that time, battery tender on a timer was installed. Left it about a week without a tender - dead flat. I charged it up, and it would not ever take less than 2A charging. Battery voltage after 3 days of charging was 11v, figured I had an internal fault and reached out to Optima for help. They entirely blew me off, said "sounds like sulfation, sulfation is normal, warranty is up to the retailer". So, a "high end" $270 "spiral wound" battery crapped the bed in under 9 months and the manufacturer says "happens, not my problem". Luckily Amazon understands customer service and sent a replacement. Five star Amazon experience, zero stars for Optima. So, I've been buying car batteries for maybe 40 years, and across my fleet I probably buy 2 or 3 a year. This was the first and last Optima I will ever buy - Not only will I boycott the brand but I will badmouth their horrible support to every racer, gearhead, weekend warrior, car enthusiast and offroader I come across until the end of my days. Garbage product (maybe I got a dud to be fair) with Garbage support. I may Fedex the defective product I got to their CEO with a copy of this review as a wakeup call to fire their support policy makers. I've never had even a cheapie battery die this quick, and even the Chinese knockoff battery vendors stand up to their warranties! I would have honestly been OK with just getting a discount on a replacement because stuff happens and we are headed to a recession - but they just told me to pound sand. Optima is dead to me now. UPDATE: replacement that Amazon sent died at 12 months and 2 weeks. Garbage product, stay away. ... show more

  • Very good battery
Product Packaging: Frustration-Free Packaging
Optima is the best battery on the market. Had to do some adaptation to my truck cable as it was told to me prior to shipping it wouldn't fit my truck. Now it's installed I know I will have a reliable and long lasting battery

  • Great Battery
Product Packaging: Frustration-Free Packaging
I have a 1994 Ford Bronco XLT and the past batteries I've used were Bosch or Champion battery size 27. A bigger battery with high cranking amps. This battery is smaller and has just as much cranking amps as the bigger ones. This battery was less expensive than the others and has a 3 year Free replacement from the Manufacturer. I live in the Desert where batteries usually last about 2-3 years but this battery will last at least 4-5 years. I say that it will last longer because a friend of mine had one in his Ford 1 ton van for four years and one night he left lights on and it died. It was completely dead, not even the done light went on. So he left me with this battery and bought another. I took his battery and cleaned the terminals and put it on my charger on 2 amp trickle for a week. When I came back to check on it it was fully charged and held a charge under load. So I put it in my truck and used it for another 2 years until it was down to holding 75% charge. I still use it for running 12 volts pumps and its been 7 years total. If that's not a good battery I don't know what is. ... show more
