I also think Odyssey batteries are the best. Here's my take: Until Sears stopped selling their rebadged Odysseys' (sears platinum) these were hands down the best battery for the money. I use several batteries in "overland" vehicles where I monitor voltage and amps. I have about that time again and variation of batteries installed in various vehicles. In my basement I've got about 6 optimas (yellow and blue top) 4 Odyssey, 8 NATO spec AGM, and about half a dozen normal lead acid batteries of various sizes all on muti stage chargers in various applications. So I go through a lot of batteries in all my various vehicles, from $650 nato AGM's to cheapy Walmart batteries. Well it's no high end battery, but it completely out performs an optima, and at only $150! I ended up going cheap for my defender and put a Wal-mart AGM battery, big boy for a Mercedes, can't remember the group size. I disconnected the battery and it still dies,(they are supposed to have unlimited shelf life). The fridge won't stay on for more than 20 min, If I let the truck sit for more than a week, she won't start(no power drain). I swapped the last one out about 3 years ago, so now the warranty is up. Well that was a mistake too, didn't last a year, and no more than 2 days with the fridge on. About 4 years later if finally died, so I put in the Autozone AGM. I could keep my fridge on all week with no problems. I had an ARB fridge, CB, winch, and inverter. I saw quite a few people swear by the Optima and so I installed a yellow top. This list is culled from the best-ranking batteries from the sources above we expect you’ll find something for everyone.In short, no they are pure crap! I used to work for Autozone, supposed to be at the time, the best store batteries on the market. The difference between cranking amps and cold cranking amps is that cranking amps are measured at 32 degrees Fahrenheit and cold cranking amps are measured at zero degrees Fahrenheit. You should also see cranking amps advertised on your battery label. CCA measures how well a battery can start in cold weather-more important for buyers in northern states-while reserve capacity is how long a battery can run if your charging system fails. The two main stats to look for, according to AutoGuide, are cold cranking amps and reserve power. The average battery lifespan, says The Family Handyman, is four to six years. Make sure your size matches up to the vehicle battery you’re replacing, no matter the type. (Those are best if your vehicle sits for longer periods of time.) They’re also better for cars with high-powered stereo setups or other extra electrical demands.īoth types come in a variety of sizes terminal locations vary from top to side. According to Consumer Reports, AGM batteries are 40 to 100% more expensive than lead acid ones, but can tolerate discharging better. Lead acid batteries cost less, but they won’t hold a charge as long as an AGM. You can swap an AGM battery into a car that came with lead acid, but not vice versa. Lead acid batteries are an older technology-you don’t have to refill them with distilled water anymore-while AGMs are modern and fit in vehicles with more advanced electrical systems. There are two types of batteries: lead acid and absorbed glass mat (AGM). Here we focus on internal combustion and what you need to know before making a purchase. Whether your car is electric, internal combustion, or remote-controlled, it will have a battery.
