  • Works great to start my boat.
Product Packaging: Standard Packaging
Works great to start a boat. As long as you disconnect the battery during extended periods of non-use, it can sit there and hold a charge for many months. Completely draining a battery is a good way to ruin it. Some things like stereos or the diodes in your alternator will slowly drain your battery when it's not being used regularly. So I disconnect the + terminal every time I park the boat. Then I use a "BatteryMinder" at 2 amps to trickle it back up to full charge with the BatteryMinder set to "AGM" before I tow the boat somewhere to use it. This is an AGM battery. AGM stands for Absorbent Glass Matt. This kind of battery seems to hold a charge a lot longer than a typical battery. And it cranks over the engine with a lot of power. I've always had pretty good luck with Optmas with the red top in cars, but decided to go with this blue top one for my boat. AGM batteries are tougher against being banged around like in a boat, a race car, a dune buggy, etc., compared to regular car batteries. And they're sealed, so you don't get a big mess of corrosion on the terminals. Happy with my purchase. ... show more

  • ORDERED NEW BATTERY - RECEIVED TWO YEAR OLD ONE INSTEAD
Product Packaging: Standard Packaging
I did a load test on this battery right out of the shipping box when it arrived. Rated at 800 CCA (Cold Cranking Amps), my load tester ran the analysis and showed a paltry 98 CCA available. Just for the sake of troubleshooting, we hooked up the battery to our Optima smart battery charger and gave it a few hours to recharge. Once it showed a full recharge, we ran the load test again...with the same exact result...98 CCA. Definitely a "REPLACE BATTERY" situation. But WHY would a brand new battery fail a load test like this? This NEW battery was replacing an older version of the same exact Optima Blue Top battery that I'd purchased in July 2017 (which had worked fine until just two weeks ago when it unexpectedly died and no longer held a charge). AMAZON customer service was GREAT as usual in shipping me a one for one replacement since the older battery was still within the 24 month warranty and I can't say enough good stuff about AMZN customer service. But the fact that the new battery was dead on arrival really had me stumped...Until I examined the bar code numbering on the old battery and the new one that just arrived... Turns out they have the EXACT same bar code numbers. Why is this noteworthy? Because the bar code numbers show you that battery's year of manufacture. In this case, both were manufactured in 2017. So that makes 100% sense for the OLD battery since I purchased it in 2017. But if I buy a new replacement battery in 2019, I would fully expect to receive a battery with a manufacturing date as recent as possible...NOT one that's already TWO years old. No wonder it was dead on arrival. It's been sitting in a warehouse on a shelf for at least two years. 12 Volt batteries have a set shelf life and shipping old ones out to customers is bad business. Optima batteries are usually good, so perhaps this is just a glitch in their system. Either way, be sure to learn how to determine the manufacturing date on ANY expensive 12 volt battery like this when you buy it so that you don't end up with a lemon. ... show more

  • Optima battery
Product Packaging: Standard Packaging
I have used Optima batteries for nearly 20 years now. I have never had an issue with them as long as you keep a battery tender on them. I’ve had some over 8 years with absolutely on problems in both of my RV’s. Now I just replaced the original on my 3 year old boat. Don’t need a bad battery in the middle of the ocean. ... show more
