That's at least a 15-pound weight reduction compared to comparably specified conventional batteries. Yet even at the other end of the company's product spectrum, Braille's more modestly priced Lightweight AGMs deliver an industry-leading energy-to-weight ratio, weighing as little as 15 pounds for automotive applications (with 425 cold cranking amps, 15 AH). Braille's most advanced lithium-ion automotive batteries are compatible with all types of charging systems (or even machines with no charging at all), hold 90% of their charge sitting idle for up to a year and weigh as little as 10 pounds. Some you can purchase from an auto parts store, while others you can simply order from Amazon.īrowse the full list before you click through, then read on for a crash course in 12-volt battery technology, signs that it's time to replace your current battery and tips toward making the new one last as long as possible.īraille Racing Batteries have sparked victories at Indianapolis, Le Mans, Daytona and racetracks all over the globe. We've based our recommendations on the work of testing labs like Consumer Reports, expert interviews, user ratings at popular shopping sites and personal experience. We've done the heavy lifting by assembling a list of some of the best car batteries available today over a broad price range, for everything from small-engine sedans to track cars to RVs. Shopping for a car battery can be complicated, but you'll regret it if you put it off until the day your car won't start. ![]() There are more 12-volt battery technologies than ever before: traditional batteries with flooded lead acid, gel, absorbed glass mat, lithium ion batteries and more. The increasing number of electrically powered systems in the typical automobile - from heated and cooled seats to start/stop auto shutoff systems - puts an increasing strain on the battery, particularly in extreme climates. If you've noticed that car batteries don't seem to last as long as they once did, your observation may not be far off the mark. Whether your car is powered by electricity or gasoline, there's no single component more vital to its consistent reliability than the battery. It doesn't matter if you have a car from the '90s or a brand new Tesla, you should have a 12-volt battery on hand. They power lights, ventilation fans, radios (or Apple CarPlay) and so much more. 12-volt car batteries continue to be the biggest part of the $100-billion auto battery market, and for good reason. For maintaining only, a lower amp charger will work (such as one in the 1-3 amp range).Every battery needs a 12-volt car battery, even that newfangled electric car you're driving around. The higher the amp hour of the battery, the more amps you'll need to charge it. Maybe three or four at the most.Ĭhoosing a charger for a deep cycle battery depends on the amp hour of the battery, and whether you want to charge or just maintain the battery. Starting batteries aren't designed for deep cycling, so they can't handle multiple discharges. What size charger should I use to maintain my battery?įor standard starting batteries, any one to three amp fully automatic charger will work fine.
