You may have a bad stator As @paulster2 stated, you should have your battery tested. You could have a lead plate the broke free inside the batter and grounding out that cel to another cel. Your voltage test could be an indicator that it is not your battery though. Here is a method you can use to test your stator. Testing Your Stator There are three ...

On the starter there will be two connections. The smaller gauge wire (s terminal - blk/wht) will run from the starter to the neutral safety switch ( A/T only - right side of transmission) and then to the ignition switch. The larger gauge wire runs directly to the battery. On a M/T the wire runs straight to the ignition switch. The larger gauge wire will ...

Your problem seems to be with the battery. It probably has a relatively dead cell in it. Old school would say it has a "surface charge" in it, where the cell will transmit enough voltage to get the motor started sometimes. When the charge isn't present on the dead cell, there's nothing to start the motor. Over a short period of time, the surface charge will ...

I recommend you carry out the following steps: Have the starter relay tested. From the description provided (old starter was clicking) this may actually be fine but it is so easy to verify that it works it would be silly to not rule this out as the source of the problem. After locating the starter relay, have someone turn the key in the ignition to start ...

Yes its possible to start a car with Ultra capacitors.These caps dont appear to have a cycle life like the traditional lead acid battery does .The ability of these caps to provide starting current is very good .There are a couple of snags :The caps at present are more pricey than the best lead acid batteries.The caps are strung in series to get the nominal ...

If you have a volt meter that you can connect to the battery you will be able to check the alternator. Before starting the engine, check the battery voltage, it will probably be a little over 12v. Now start the engine and turn on your headlights to draw some power. If the alternator is working, the battery voltage should now be between 13.8 and 14.4 ...

To answer the title question, no. I've worked in several automotive retail outlets and have never seen an automotive battery not precharged. They may exist, but it would be an odd sight to see. Automotive batteries are very frequently purchased and installed in the same transaction. The batteries in which you need to put in the electrolyte, you also need to ...

Since the drain is very repeatable, connecting an ammeter in series with the battery and disconnecting each fuse in turn is a good idea as @jphil1618 suggested. You could find that the problem is associated with multiple fuses, for example it could be the fuel pump that is running (I know you would hear the pump) and while pulling the fuel pump fuse will ...

I put a AGM battery in my audi a4 1999 , and the computer got confused enough to throw up annoying symbols on the dash , like bulb out errors and the like , so i changed back to excide premium 90AH , I recon the cars computer just could't figure out what had changed ,with the AGM being able to be recharged 5 times faster than the standard battery , but no ...

I agree with Steverrill but it was partly correct. Let me give the clear explanation, why actually the Headlight Dims? In actual the headlight will not dim, it was turned off during the engine cranking. This is because the starter motor is the battery hogger(It will drain out the complete battery in the matter of 15-30 minutes continues run). So the ...

Wesayner explains how this works, but admits that the measurement is subjective. It's not a good way to tell the state of your battery, but it will tell you if a dead battery is the reason your engine won't start (or, more specifically, won't turn over.) The starter is connected to the battery by a relay: the keyswitch operates an electromagnet, that ...

A lot of times, I use a "water in a pipe" analogy when I think about electricity. In order to explain why the lights dim when you start the car, consider the following: your car, on average, uses a reasonable amount of electricity. This electricity can be considered equivalent to water flowing through a pipe, let's say a 2-inch pipe. When you turn your ...

The car will be fine, that's just the noise the starter motor/solenoid makes when the battery is flat. The solenoid switches on the motor and engages the motor's gear with the flywheel, allowing it to turn the engine. There is a strong spring which pushes the solenoid back to its resting position after use. When the battery is very low it can't supply ...

You need one of 2 things - volts or amps. To jump start the car, you need something with 12-14v and able to crank out 100+ amps. You can charge your battery with anything with a higher voltage. There is a video of someone charging his battery with a bunch of AA batteries in series. You have to let it sit for a bit. This is only going to work if you ...


3

No, you can't. A car battery needs a lot of amps at ~12v, and most USB outlets are rated between .5A and 2A at 5v. Car batteries run in the hundreds of amps at 12v. Water hoses often make a good analogy for electricity. Think of amps as the width of the hose, and volts as the speed that the water is flowing at. Your smartphone powerbank is a hose the size ...

tl;dr: You are doing a better job than most, and as a result reducing your chemical footprint further will largely require being more proactive about safe chemical disposal than most people are willing to be. Having said that, there are a few things to consider. Reduce the amount of waste that you generate where possible. The best thing I can suggest for ...

You have another issue The battery doesn't sound like to the core issue that you are experiencing. I propose that your stator or rectifier have gone bad thus you are experiencing a situation where you have to have your battery serviced. The motorcycle should be 'servicing your battery' and charging it as you ride the motorcycle. You will want to test ...

I took the care to the a mechanic and they said it was or could be two things: When the battery dies sometimes the internal computer\memory needs to be reset. The car's throttle body needed cleaning. So far it has not stalled after having both of these done (5 days now). Not sure which of the above actually of the above fixed the issue ... maybe both. ...

As mentioned in the comments, I think what you need to do is verify that you have obtained reliable data about the status of your battery before you come to any rash conclusions. I am wondering why the tests came back fine unless there's a fault in my method? Yes, there probably is. Does this indicate that the battery needs replacing? A trickle ...

I took it to a main dealer and had the car diagnosed there. They replaced the battery and so far the car seems fine. I guess that battery test equipment can only test it to a certain degree - e.g. it can tell if a battery is definitely gone. In my case it was gone but undetectable by such equipment.

There are a number of ways to go about purchasing a new battery for the vehicle. Easiest way would be to find the part number and see if any of the local parts stores have the same part number or can cross reference that number to the batteries they sell. For example an: LM40CP - Manufactured by Exide is equivalent to an NS40ZMF - Manufactured by ...

Walmart says your vehicle requires a MAXX-51R which is a 500 CCA battery. AutoZone has it as a 51R-DL which is a 475CCA battery. If you go to Google and search on the key words "vehicle battery finder", you'll be able to find several search pages which will suit your needs. You or anyone else who is in search of one will have to go this route or go to the ...

I fixed this. Here is what I did: I added a fresh, new battery. It was going to be needed regardless as the battery was producing corrosion, a good sign the battery is at the end of its life. I put a fresh terminal on the damaged terminal where there was corrosion. I stripped the old wires and slapped on a 5 dollar terminal from autozone, plugged the bad ...

Turns out the problem was the key security system. Apparently the switched voltage reset the key security, which caused my key to not be recognized by the car. After getting the security reprogrammed to accept my key, the car works as usual.

Sometimes not everyone can just buy parts... So if I can just charge my battery up to start my car then it's cheaper than getting the battery. If the alternator fails before I can "find" a battery then I deal with that when it comes. Also maybe more actual use is the do-it-yourself type because we learned that if I'm prepared I'm ready. Never know who may ...

The firmware on the navigation system of my Honda takes over an hour to update. It's much "greener" to clip a battery charger onto the battery than it is to idle the engine for that long. I'm not sure I'll actually need it to charge the battery, though. Oh...I also use it to keep my extra gel-cell batteries charged, too.

In my case the battery charger is kinda like snow tires and synthetic oil; I like the extra assurance, but I can get by without it. Also, my wife owns a robot-fly-by-wire-electric-everything van that is particularly hard on the battery, and after replacing a third battery in 8 years I thought this might help with reliability. Given that the charger I bought ...

This exact same issue happened with me in a Ford Focus. As rpmerf said, check the terminals. In my case, after removing the terminals from the battery and reseating them, the car cranked over fine.

maybe you can fit a a battery with more reserve power

All batteries have a self discharge rate. This comes form the inherent nature of their chemistry. Lead acid batteries are one of the worst offenders when it comes to their self discharge rate. The estimates are all different but between 5% and 20% of capacity discharge a month is the general consensus. Because the discharge rate is a function of current ...

adding a diode would probably be counterproductive as it will cause an extra voltage drop, I'd look into fitting a relay such that the socket was not connected during engine start.


3

Disconnecting the battery messes up your radio, etc. Instead of a diode which causes a voltage drop you could put a 55 W lamp in series. It will limit the current to the battery but as the battery charges up the voltage drop across the bulb will reduce and the battery gets full alternator voltage. When cranking the motor home its battery voltage may drop to ...

The fastest, cheapest and easiest solution is to add a battery disconnect switch to the car. After placing the ignition switch into acc mode the open the hood and disconnect the switch. When you arrive at your destination, open the hood and reconnect the switch. This costs under $20. It also eliminates the need to run anything or calculate anything. Many ...

Your Problem There are a few reasons that you might have your engine cut out. If you have any error codes (found by plugging in a scan tool to the OBDII port on your car), they would help dramatically in being able to narrow down the array of possible answers to your problem. If you do have a faulty connection, which I don't think you do, then a code ...

It depends on the health of the battery before it was discharged and how long it was discharged. Working at a shop, we would top off the cells with distilled water, charge the battery overnight, then test the battery to see if it was still good. You can either charge it (2A overnight or 10A for about 1-2 hours) or jumpstart the car and run it or drive it ...

Repeated clicking is a result of not enough power making it to the starter. Your battery either has a bad connection, or is too weak to turn the starter motor. Battery Connection Your problem may be entirely due to a bad connection. Starters draw a lot of amps, and batteries are weaker in cold temperatures. I'd start by fully exposing the terminals. You ...

Starter/Solenoid: The starter spins your motor up, the solenoid pushes the Starter & Engine gears into contact during starting. Sometimes things get sticky from corrosion or dirt inside the Starter/Solenoid and you'll hear a click or two when you try to crank. Solution: Find your starter and give it a couple of soft to medium TAPS with a hammer (bonus ...

This could be caused by multiple things, the most likely case would be a bad battery in need of replacement. However before coming to that conclusion there are a few things which can be checked. Make sure your battery terminals are in good working order and are not grounding out any where make sure they are insulated and not cracked and touching metal. ...

A car battery's power will drop with temperature. It would be my first port of call. Since the car ran fine when you had it jumpstarted with the help of your friend, I would have the battery tested to make sure that it can deliver sufficient juice to the starter.


1

A reasonable answer depends on how old the battery is. The expected lifespan of a lead acid battery is about 4 years. If your battery is nearing or over the 4 year mark, it would make sense to replace the battery as part of your standard maintenance cycle anyway. Putting it on a slow charge overnight / over a day wouldn't be a bad idea, at any rate, even if ...

It depends - If your car is a second hand one it might need replacement. I used to own a Nissan Micra, and the battery was wiped out due to a similar accidental leaving of keys in the car with the lights on. The Micra's battery was never the same after that - already not brilliant at holding charge, leaving it to go flat was the nail in the coffin that ...

1) From an electrical perspective, you always connect negative of charger to negative of battery. The closer the better (i.e. put the clips directly on the battery) to avoid losses and heating in the wiring of the car. To check for this put your voltmeter across the battery when you are charging, then put it across the output of the charger. Any difference ...

If your Alarm is going On after replacing Your battery. 1 there is a code you need to enter into the FACTORY radio. The radio is part of the alarm system. You must Pull the radio and Call Acura dealer/ Acura themselves. There is an 8 digit code that will give them the 5 digit code you will need to enter. (write it down on owners manual for future ref.) ...

The battery should simply be recharged. Draining a regular automotive battery is not good to do on a regular basis, but doing it once isn't going to have a noticeable ill effect. Giving the battery a full charge would help it, and it's more than most people would do. Most will just jump start the car, and hope for the best from alternator charging. That ...

Cars commonly multiplex their electrical systems. This means that multiple things are fed from the same fuse. The best way to identify what is on the fuse is to check the wiring diagrams. Once all the possible sources from the fuse have been identified the fault can be systematically narrowed down. First look at components that come on and off, this is the ...

As Paulster2 said, any bare metal should provide a good ground. Most common places to attach leads in your situation would be a lifting eye (if your engine has them), the body of the alternator is normally easy to attach to, or any metal part of the engine. Also make sure the metal you attach the lead to is capable of carrying enough current to start the ...


1

AS mentioned. It is a shared ground (all exposed metal is a ground. So connect to any none painted metal. Though they normally have a bolt or something to attach to near the battery.

They are right. Its not a problem yet. There are no signs that battery fluid is escaping through the post. Keep an eye on it, though. :)

Yes, as everyone is stating, a spark igniting hydrogen gas could cause an explosion, causing injury from small parts, sulfuric acid or both. Very nasty. Hydrogen gas is a byproduct of electrical energy created from a chemical reaction of lead plates submerged into the acid and water. Sparks can happen internally, too. Like when the lead plates warp from ...
