Car Battery Buying Guide

Maintenance-free batteries use calcium alloy of lead instead of an antimony alloy which is able to sustain the water longer without refilling, but certainly not forever! Any abnormal electrical system condition or high ambient temperatures may boil off more than the normal amount of water. Aug 04,  · A maintenance-free vehicle battery is one that is not designed to be opened or refilled. The liquid solution in conventional lead-acid batteries can evaporate, lowering the level in the battery and rendering it inoperable. Sealed batteries use materials to fix .

What does "maintenance what color are your skittles mean on your car battery? Does it batterry that you have to discard it if it goes dead?

It simply means that you do not need to add water to it on a regular basis. The batteries of only 20 years ago required water to be added on a regular basis. If you have a problem with your maintenance-free battery, it can be tested to determine if it can be reconditioned or replaced.

This testing requires some basic electrical tools as well as common household tools and can be done at home. Open the hood of the car and remove the battery cables with a wrench. Lift the battery out of its tray and place it on a work bench. Put on safety glasses and rubber gloves.

Clean the battery posts by placing a battery post cleaner on each battery post then twisting it back and forth until the posts are clean and bright. Connect a load tester to the battery's positive terminal first then to the negative post. Connecting the positive terminal first will prevent sparking. Switch the load tester to "TEST" and check to see that the arrow on the meter does not drop below 12 volts. If it does or if it drops to the bottom of the what is meant by technical support engineer and fails to come back up, the battery cannot be saved and must be replaced.

If it reads 12 volts, it can be reconditioned.

Fact About Maintenance Free (MF) Battery

Apr 02,  · Maintenance Free’ is an unfortunate label for an automotive lead acid battery as all batteries require some maintenance (keeping the battery top clean, keeping attached cables tight and clean, keeping the battery charged or re-charged as soon as possible following a . Jan 03,  · Today’s automobiles are typically equipped with maintenance-free batteries, but that doesn’t mean they don’t require a bit of tender loving care. Such batteries usually come with vent caps that are sealed, which means you no longer should check water levels — . "Maintenance Free" means that the manufacturer didn't provide any means of maintaining the water/acid level in the battery, which means that if a battery boils dry you can only replace it instead of refilling it yourself with water or acid, whichever is appropriate (probably water).

Such batteries usually come with vent caps that are sealed, which means you no longer should check water levels — a requirement of some earlier batteries. The first rechargeable batteries for commercial use were composed of lead-acid, and those components are still used to this day.

But earlier car batteries were not as evolved as those used today, which now come with a more durable construction and contain a highly sophisticated blend of alloys that helps reduce water loss and self-discharge. Computerized equipment and robotic processes have also evolved batteries to store and deliver power with peak efficiency lasting much longer than traditional designs. Most batteries feature vent caps that do not allow you to open and add water, and the warranty often becomes void if you do.

Although the inside of a maintenance-free battery cannot be physically cared for, the outside certainly can.

Try following these steps to ensure that the exterior of the battery is in top shape, and you can extend its life:. If you live in a hot location, you may have noticed battery life is shorter than expected.

Indeed, heat causes the water inside the battery to evaporate and accelerates internal corrosion. A tool to include in your collection is a multi-meter , which is useful for conducting a full range of standard electrical tests in a car.

He since moved on to learn a few things about coefficient of drag, G-forces, toe-heel shifting, and how to work the crazy infotainment system in some random weekly driver.

Battery Care Although the inside of a maintenance-free battery cannot be physically cared for, the outside certainly can.

Try following these steps to ensure that the exterior of the battery is in top shape, and you can extend its life: Protect yourself. Before you start, put on a pair of gloves and wear eye protection. Batteries contain an acid, which can damage your skin or eyes if an accident happens. Disconnect the battery from the cables.

Unhook the negative black cable followed by the positive red cable. Remove the battery from its tray and set it on an even, smooth surface. Examine the battery, looking for cracks or other damage. If damaged, replace it at once. Clean the cables and terminals. If the battery is in decent shape and passes a voltage test, then clean it before returning it to the tray. Remove the corrosion white dust-like build up on the cables and terminals with a wire brush.

Another method for removing residue is to add a tablespoon of baking soda to a cup of water and stir. Next, pour the solution directly on the corrosion to dissolve it.

There are also terminal cleaner sprays that do a fantastic job with less of a mess. Lastly, wipe clean with a rag.

Before you return the battery to the tray and reconnect the cables, spray the appropriate areas with battery-terminal protectant. This optional step will mitigate future corrosion build up. Attach the positive cable first, followed by the black cable.

Start the car to ensure the battery is working. Some Like It Hot If you live in a hot location, you may have noticed battery life is shorter than expected. Categories Maintenance Tags batteries , battery , car battery , car care , car maintenance , charging system , lead-acid battery.
