Car Batteries

Car battery is the heart of the car’s electrical system. It usually refers to an SLI battery (starting, lighting, ignition). Automotive battery is a lead-acid, rechargeable battery that provides 12-volt potential difference from six cells connected in series.

How do you change the battery on a 2003 Cadillac CTS?

Make sure the keys are out of the ignition first. Then check to see if your vehicle has any braces holding it in place. Once you've taken any braces off, disconnect the ground wire(black), it useally takes a 1/2 inch wrench. Then take your hot wire off(red). These are all the workings of a person being self sufficient. Good luck.

What happens if a car battery is not used for a long time?

User Avatar

Asked by Wiki User

If a car battery is not used for a long time, it can experience several issues due to a process called self-discharge and other factors. Here are some potential problems that may arise:

Self-Discharge: All batteries, including car batteries, naturally lose their charge over time, even when not in use. This is known as self-discharge. The rate of self-discharge depends on various factors, including the battery type and temperature. If the self-discharge is significant and the car is not used for an extended period, the battery may drain completely.

Sulfation: When a lead-acid battery, common in many cars, is left in a discharged state for a long time, sulfur crystals can form on the lead plates inside the battery. This process is known as sulfation, and it can reduce the battery's ability to hold a charge. In severe cases, sulfation may lead to permanent damage.

Low Voltage: If the battery voltage drops too low, it can affect the performance and lifespan of the battery. Modern vehicles with advanced electronic systems may experience issues or malfunctions when the battery voltage is too low.

Freezing: In cold climates, a partially discharged battery is more susceptible to freezing. When the electrolyte inside the battery freezes, it can cause internal damage and reduce the battery's effectiveness.

To prevent these issues, it's advisable to take certain precautions if you know the car won't be used for an extended period:

Keep it Charged: If possible, use a battery maintainer or trickle charger to keep the battery charged. These devices supply a low current to the battery, preventing self-discharge and maintaining an optimal charge level.

Disconnect the Battery: If you're not using the car for an extended period, consider disconnecting the battery to prevent any slow discharge due to the vehicle's electrical systems.

Store in a Controlled Environment: If feasible, store the vehicle in a cool, dry place. Extreme temperatures, whether hot or cold, can accelerate the self-discharge process.

By taking these precautions, you can help ensure that your car battery remains in good condition, even if the vehicle is not used for an extended period.

How long does it take to charge 6 batteries in a golf cart?

User Avatar

Asked by Wiki User

average golf cart battery is 110 amps. if you have 6 batteries in a 36 volt system, and you use a 20 amp charger it could take up to 5 1/2 hours (depending on the state of charge of your batteries when you begin the charge). Were they at 50% charge? Were they at 20% charge? Pop a cap and check with a hydrometer before you begin your charge and then you can calculate how long. Be sure and use the amperage of your charger in the formula.

How do you replace the speedometer cable on a 1989 Ford Crown Victoria?

User Avatar

Asked by Wiki User

Before you go any further, double-check to see if this car actually has a cable. 1989 Crown Vic and Marquis cars should still run a cable; 1990 started using an electronic vehicle speed sensor (VSS) in the transmission for speedometer - if this is the case, the problem will be an electrical one. Why does the cable need changing - is it broken? (Did the speedo stop operating?) The speedo cable is a cable-in-a-cable setup; there is a small diameter steel wire (called the core) inside a housing; it couples the drive gear in the trans to the gearing in the instrument cluster. To change it, you will need to remove the instrument cluster out of the dash, disconnect the speedo cable housing from the cluster and pull the section of core out by pulling and wiggling it. If it's broken, you'll see a sharp cut section of wire. The transmission end might be more difficult if you have to pull it as well; old style cables either have a big threaded collar or a clamp with a bolt or nut to hold it into the trans. (The whole length of the cable core should come out from the dash if it's not broken.) If you need to change the whole cable assembly, the trans end will need to be pulled off as above; the front section will pass through the firewall and up into the cluster. From experience on my '89 Grand Marquis, pulling a cable core is time-consuming and difficult; there is not a lot of room to work with. I would first find out from a Ford dealer how available replacements are; otherwise, the wrecker may be the only place to find them. If the cable core is in good condition, no signs of rust or seizure, then the speedometer head (in the cluster) or the drive gear (in the trans) may be at fault. Hope this helps.

How long to charge 18 volt charger?

User Avatar

Asked by Wiki User

The battery itself should last almost indefinitely, although the charge on it won't.

That depends what you use it for. If you load it lightly or not at all, such as leaving

it on the shelf, it will last quite a long time. Whereas if you load it heavily, such as

to energize a parallel bank of high-intensity incandescent lights, the life of the

charge on the battery will be comparatively much shorter.

Does charging your phone in the car affect the battery?

User Avatar

Asked by Wiki User

If you're asking about the car battery, the practical answer is "No."; the drain on the car battery would be negligible. The current used would be significantly less than 1 of your interior dome lights while the phone is charging, and once the phone is fully charged it (and the charger) would consume even less.

If you're asking about the phone's battery, the only effect would be a charged battery. The process does not promote an unhealthy state for either battery in any practical or realistic scenario.

Why the positive terminal of an ammeter is connected to the positive terminal of battery?

User Avatar

Asked by Wiki User

The proper polarity has to be adhered to so as to make the meter's needle deflection move in the correct direction. The wrong polarity will deflect the needle in the opposite direction and pin the needle against the needle stop on the left side of the meter's scale. This could un-calibrate the ammeter and the readings would not be accurate if this happens.

Can you use 12v charger to charge 14v battery?

User Avatar

Asked by Wiki User

You have to know the current rating of the battery (Will tell you how many amps or miliamps can be supported by unit time) and you will have to know the voltage operating range of the devices being powered. Usually there is some slop in the voltages so you could get away with it, but you could also shorten the life of the devices involved or burn them out.

Jaguar XF 2009 Battery fob

Remove the two metal oval bands (one on either side) which can be done just using fingers or a small screw driver. Make a note of the positioning of the indentations in the bands which are for the pull out key

Open up the key fob mechanism again with fingers or a small screwdriver. The CR2032 battery is obvious and interfaces with the printed circuit board. Replace battery which just pops out of its plastic mounting and reassemble. Polarity is marked on the plastic to indicate which way up

Be careful of the spring loaded mechanism which retains the removable key in the fob but it is easy to reassemble of it does come out of its guiding slot

What is the purpose of batteries in series?

User Avatar

Asked by Wiki User

the positive piece on the first battery is connected to the negative piece on the next battery in the series and the negative pole from the first one is the negative you connect to the device you are powering and the positive pole on the very last battery in this series is the one you connect to the positive terminal on your device.
