There may be signs a car battery is on its last leg.

One-year full replacement warranty, but with proper care and feeding, it should keep you rolling for years. Venerable capped lead-acid tech delivers excellent cranking power. Guaranteed to never drain below the point where it can't start your car.

Just press the button on top of the battery, or use the standard key fob you can leave on your key ring, and voila! The battery you thought was dead quickly fires its host machine.īlue blood AGM rated highest among dozens tested in Consumer Reports labs, with "no discernible flaws."Ĭonventional lead-acid outperformed batteries costing two or three times as much in lab tests. It always leaves enough juice for a steady burst of cranking amps. If you forget the interior light when you get to the airport, the chip will essentially shut down the battery before it's completely drained.
Slickest of all, the Re-Start should never go dead, and you should never, ever need a jump. It's warranted for five years, with the first three full replacement and the last two prorated. It all helps to extend battery life, and Antigravity says the Re-Start should last seven to nine years, depending on climate. BMS prevents overcharging and overdischarging, and its thermal management system balances cell use to optimize operating temperature. The tricks, after the lithium chemistry, start with a chip-controlled Battery Management System. They're available in many automotive group sizes, with multiple choices in cranking amps and reserve power. The Antigravity Re-Starts aren't cheap, but they're exceptionally light (all under 20 pounds) and loaded with high-tech features. Finally, included the Renogy Lithium-Iron Phosphate for its intelligent battery management protection system.Antigravity was a pioneer in lithium technology for portable jump starters and energy storage, and it has expanded into powersports and automotive batteries with its Re-Start series. Added the Amstron GC2 for the ability to withstand freezing temperatures and for its low gas emissions. Also included the DieHard Advanced Gold for its durable construction and electrolyte suspension system for protecting the internal components. I also thought the Optima BlueTop was a versatile option, thanks to its support for multiple mounting positions as well as the use of spiral-wound cell technology to minimize vibrations. Also added the Odyssey Thunder Marine due to its use of virgin lead material for maximizing surface area and reserve power. The Renogy AGM has a low self-discharge rate, which is helpful when having to store it for long periods of time. I included the Battle Born 12-Volt because it can last for up to 5,000 charge cycles before requiring replacement, while offering a 100-amp continuous output. For that reason, I tried to focus on including durable, spill-free options with high charging cycles and an ability to withstand extreme environments, too. While starting up a boat engine is definitely important, I wanted to make sure this list captured plenty of deep cycle options as well, considering that most watercraft are equipped with all kinds of electrical equipment requiring steady energy flows to keep them running.
