Bear in mind, manufacturer warranties are often not supported when parts and accessories are purchased online from retailers like Amazon or Walmart.įinally, be forewarned: Some brands, such as BMW, require the battery to be " coded" (digitally mated) to the car or it will not take a charge. Two hours is better.Īlso important is the warranty, which should be at least three years for full replacement (assuming no signs of neglect or abuse), plus, in some cases, a prorated refund for some time after that. Three More Things You Need to KnowĪnother number to understand is the battery's reserve capacity, which is how long it can provide power with the engine off and headlights and/or accessories on or if the vehicle's charging system fails. A bigger number is better, especially in cold weather, when batteries are at their weakest. The next thing to check is the engine-cranking power of a vehicle battery, which is expressed in cranking amps (CA) and/or cold-cranking amps (CCA), a measure of how much electric current (in amperes) it can deliver for 30 seconds at 32 and zero degrees Fahrenheit. They are likely not offered in the right sizes and specs to support modern cars, however. ![]() Those old " wet cell" batteries from Dad's day are still available, though primarily for older models or penny pinchers. Gel-cell batteries are best for deep discharging but may have problems in extreme hot or cold. They use similar chemistry as SLAs but are more durable and are claimed to stand up to more charge cycles. These SLA batteries use the same chemistry as the ones your dad had to periodically top off with water, but today they are sealed-hence the name-and maintenance-free.Ībsorbent glass mat (AGM) batteries have quickly become the norm for most modern cars. MarkSwallow | Getty Images Know What Type of Battery You NeedĪlmost all cars come with a 12-volt sealed lead-acid (SLA) battery of some variety (a few high-performance cars are equipped with lithium-ion batteries). Again, you can find which size you need in your owner's manual, in the replacement guides at the retail store, or online. Size 48H6 (top terminal) batteries fit many European and American vehicles. A number of sizes fit today's wide variety of vehicles.įor instance, size 24/24F (top terminal) batteries fit many Honda, Acura, Toyota, Lexus, Nissan, and Infiniti vehicles, while size 35 (top terminal) units fit many other Japanese vehicles, including recent Toyotas, Nissans, Hondas, and Subarus. Regardless of whether you're doing it in your driveway or letting a shop install, it's a good idea to first make sure you're buying the correct physical size. Just remember, the negative terminal is always the first thing you disconnect and the last thing you reconnect. But some are buried in the trunk or elsewhere-not so easy to find, let alone remove and replace. Most batteries are located up front, under the hood, where they're easy to access and replace with a couple of wrenches. How to Disconnect Your Vehicle's Battery.is looking to ramp up its own rare earth refining and mining industry to catch up with China. Given the strategic importance of such rare earth metals and China's mining dominance of them, there has been concern from Washington that Beijing could cut off critical supplies of lithium and other materials. Lithium is a critical metal for batteries that go into everything from electric cars from smartphones. ![]() "In the case of the investment on this proposed project in Texas, the decision will be based on a number of commercial and financial considerations, including the ability to obtain relief regarding local property taxes," according to the application. Tesla said the only way this project will be viable is if Texas gives it tax breaks under its law. Musk's firm said the project could be located "anywhere with access to the Gulf Coast shipping channel." Tesla said it is evaluating a competing site in Louisiana. No engineering, construction or procurement construction contracts have been negotiated or signed and no regulatory permits have been obtained, Tesla said. Tesla said that it is still "evaluating the feasibility of this project" and "only very preliminary development activities have begun." The project will reach "commercial operations" by the fourth quarter of 2024. ![]() If Tesla's application is approved, construction could begin in the fourth quarter of 2022, the company said.
