    • BEST BATTERY YOU WILL EVER OWN FOR 10+ YEARS !!!!!
Product Packaging: Frustration-Free Packaging
The last Optima Red Top battery I bought lasted me 10 years and I was very upset when it was "accidentally" traded in with a vehicle it wasn't supposed to be in. If that hadn't happened maybe it could have still been going I don't know... MAYBE IT STILL IS !!!!! I'm going to be completely honest here, when the DieHard I had in my pickup AS THE REPLACEMENT FOR MY RED TOP THE DIEHARD DIED VERY EASILY as in LESS THAN 3 YEARS. What absolute junk AND it was nearly $200.00 !!!!! If I can stress anything here PLEASE DO NOT BUY A CHEAP BATTERY. You always get what you pay for, I bought junk I got junk don't make my mistake. I will take a KILLER battery and cheap jumper cables ANY DAY over a cheap battery and a expensive jump box. ANY DAY. ... show more

    • A Good Starting Battery
Product Packaging: Frustration-Free Packaging
I ordered this battery (34/78 Red Top) for use in my '66 Ford Bronco. I needed a battery with more ooomph than a standard battery. The battery was extremely well packaged for shipment. There was more than enough protection to prevent the battery from being damaged. The battery was charged up. It comes with a top plate, though I did not need it for my application. The price on the battery was excellent, though it's likely due to a couple of considerations. First, the battery is covered by a warranty. However, it's going to be more complicated to handle it than if you purchase it from a local dealer. Warranty on the battery involves shipping and waiting. That is not likely a good option for someone using their vehicle on a daily basis. On a part-time vehicle, that won't be a problem. And then there is the hassle of disposing of the failed battery which you are replacing. So plan on a trip to your local hazardous waste recycling facility. Or at least to a nearby auto parts dealer - hoping they will just take it off of your hands. After installation, my Bronco started right up. It's been a couple of months now, and no problems or hiccups. But with all batteries, the real test is time. I am hoping to get several years of service out of this battery. Shipping was faster than they indicated, though not 2-day Prime. Overall, a good purchase on an accurately described item. Note: The price of the battery varies considerably. I chose the lower priced battery with a slightly extended shipping time. ... show more
