The XS Series 12 Volt Deep Cycle AGM Batteries puts out an outstanding 1150 cranking amps which allows any car or truck to start in any sort of weather conditions. You\u2019re going to be paying for this kind of power, though, as even the cheapest price on Amazon is still expensive. Check out our best car battery list for more great options!\r\n\r\nWhy We Like It - XS Power D3400 High Output Battery\r\nThe XS Power D3400 High Output Battery is especially good for car audio systems thanks to the amount of raw power it has and includes an M6 terminal bolt so you can get straight to mounting and then straight to driving. Just make sure you\u2019re getting the correct make model as there\u2019s a less powerful, 1000 amp version too.\r\n\r\nPerformance\r\nThe XS Power Batteries uses the highest density chemistry in AGM BCI group batteries which makes it the battery of choice for car audio systems. The XS Power D3400 High Output Battery lives up to its high output name with an outstanding 1150 high performance cranking amps. With this amount of max amps any car or truck will be able to start no matter how cold it is. But if you live somewhere that doesn\u2019t normally get below freezing, try the Optima Batteries 8020 164 35 Starting instead.\r\nDesign\r\nThe XS AGM High Output Battery features an absorbent glass mat AGM design with a sealed lead acid battery. This all combines to give the battery an increased tolerance to vibrations so it can last longer. The battery is also spill-proof which allows for mounting freedom without the worry of acid or electrolyte spillage. Upside-down isn\u2019t recommended though for obvious reasons. You can also check out the Optima Batteries 8014 045 YellowTop Purpose for another example of a non-spillable, mounting freedom-type design.\r\nValue\r\nThe Power D3400 XS Car Battery comes included with an M6 terminal bolt so you can get your mounting started right away. But be aware that it does not come with battery posts which must be purchased separately if you don\u2019t already have them. It\u2019s also not directly sold on Amazon and must be purchased from third-party sellers. The cheapest is still a whopping $333.00. If you want something a little more affordable, consider the ODYSSEY PC680 Odyssey Battery.\r\nXS Power D3400 High Output Battery Wrap Up\r\nThe XS Sealed Absorbed Glass Mat AGM Battery has a spill-proof design that allows for mounting freedom (aside from upside-down) and is resistant to vibrations, a car battery\u2019s natural enemy. You\u2019ll have to buy the battery posts separately, and with how much this battery already costs, you may not want to incur the extra expense.
