I have a question. I have a roommate who thinks he knows everything and has a fit with me leaving my coffee pot plugged in because of cost. He stores around 10-15 car batteries in the basement that are all connected to eachother with a main charger plugged into the wall. I had no idea about the dangers of batteries in the house, but I know that has to be ...

Disconnect the battery negative. You'll lose radio presets and ECU learning, but nothing else. I don't know what vehicle you have so it's hard to judge how difficult this will be, but I doubt much. 10mm wrench and 5 minutes. A one-beer job.

I don't know the exact model of the trickle charger, but would suggest against using it and getting an actual battery tender instead. The difference is, the trickle charger will continue to charge, but at a really slow rate. This means, you can over charge the battery and cause damage to the battery with it. A battery tender will keep the battery in tip top ...

Lead-acid batteries contain a solution of sulfuric acid (H2SO4) and water -- the solution is referred to as the battery's electrolyte. Adding a solute (in this case, H2SO4) to a solvent (in this case, H2O) will lower the freezing point of a solution. A fully charged battery has more H2SO4 than a discharged battery. The additional H2SO4 depresses the freezing ...

Sounds like he bought a new battery to try to fix the issue but it did not. There may be other causes (like fuses, wiring, a non-genuine immobilizer) but the next logical assumption is that the starter and/or starter solenoid have failed.

Yes, they can be. You'll probably need to find a company that refurbishes batteries, there's one that I know of in Australia so I'd say (i.e. assume) that there would be services in your area. If you're a bit handy with electrical work, I've seen some people set up arrays of smaller lithiums to achieve the desired outputs for EV applications. It's not ...

More than likely a Bad ignition switch (lower steering column), replace it, sometimes it burns the big 12v wires at the switch and you have to repair the wire ends with new ones or get a ignition switch repair pigtail and splice it in.

Have you checked the battery condition? Your local motor parts supplier should be able to test it for you, and replace it if it's failed. As a guide, batteries usually last 5-8 years, so if it's in that range or older, you'll probably need to replace it. Also check the condition of the connections to the battery terminals, and the condition of the ...

Connect it to the engine block: A bolt on the engine end of one of the engine mounts, or one of the bolts that hold the starter, but not a hot spot like one of the exhaust manifold bolts. Anywhere on the engine block is pretty-much equivalent so connect it to the most convenient place.

It really depends how much power the "popper" needs to pop: 8AAs might be enough, 9 or 10 might work better (15V isn't going to damage anything) or you might need fatter batteries, C or D on the other hand it may be that your charger can be connected to the fuse and have enough power to work the latch.

You can do it, as long as it does not take huge amounts of current. Make sure you ground the batteries' ground to an UNPAINTED screw.

Depends on what country you buy it in what type of date code they use. Date code is engraved or hot stamped into the battery case somewhere This chart is for Automotive, Marine and Motorcycle batteries, but may apply to other types. Yes they made a mistake on the chart, "explanation" section for Philippines and Korea are swapped source: ...

Absolutely! In fact, you don't even need the amount of power which would come out of a standard battery to accomplish your needs. You just need enough power to get the hood to pop! Really, all you need is a 12vdc power source. A truly easy source of this would be to get one out of a battery backup system from a garage door opener. Another way to do it is to ...

The white substance which you see around battery terminals is either lead sulphate or anhydrous copper sulphate . Anhydrous copper sulphate changes to blue colour when water is added to it. The bluish substance which you see around corroded copper terminals or copper clamps is hydrated copper sulphate. Cleaning Corroded Battery Terminals: To clean lead ...

The others have stated great facts however, if you needed a jump and it fired right up, I wouldn't leave the cables hooked up for more than a few minutes. You need to check to insure that your cables are clean and tight and that the ground is good wherever it leads to the frame or engine. Also check to see that your alternator is putting out/charging. You ...

As Moab's answer said, the best option is to use a battery charger. However, if you don't have time to wait for the battery to recharge: You could leave your engine running stationary to charge your battery, but that's really inefficient and takes forever (see below). You're better off taking a long drive. It will take a while to recharge the battery; I ...

Charging a dead battery using the alternator is hard on the alternator, it is best to use a Battery charger. Alternator manufacturers know the same things about alternators that we do- they are designed to maintain batteries that are near a full state of charge, not recharge deeply-discharged batteries. We post this on message boards all the time, but ...

Firstly, the reason for connecting the positive jumplead before the negative jumplead is that so that if it slips off, you will notice this before connecting the negative one. If you connected the negative one first and then the positive one, one of the positive crocodile clips could slip off, make contact with the chassis of one of the vehicles, thus ...

This is going to get a bit technical but should still be understandable even if you slept through chemistry classes. When is hydrogen dangerous? Just as with the fuel-air mixture in an engine, hydrogen is combustible only when it's within a range of concentrations. We use what are called the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL) ...

I am no expert in this topic, but I don't think a "cloud of gas" forms around the battery. Hydrogen gas is the lightest gas of them all (0.089 g/l) and won't pool up if leaked. It will simply rise as long as the bonnet is open because it is less dense than air, which is mostly much heavier nitrogen (1.25 g/l) and oxygen (1.4285 g/l). My guess is that the ...

If your battery has the ability to add water to it. Do it only after the battery has been charged overnight. Never add water to a dead battery prior to charging. When a battery charges the plates thicken and as a result the water level rises in the cell. Filling a dead battery results in leaking electrolyte (water and acid mixture) which would have to ...

Alternator charges the battery at a regulated 5 A/h. It charges at a much lower rate than specified on the batteries usually 1/10 of their capacity. This is because charging at full pin would overheat the battery, generate high levels of hydrogen gas and dramatically reduce the longevity of the battery. 61 A/h battery at 5A/h charge rate would fully charge ...

Just to post the OP's answer to get this closed out: "I just got a new battery a few months ago took the jeep up to napa they tested it n its a bad alternator."

There are three different tests you can do to check your charging system and battery (there are others, but I'll just talk about the big three): Voltage with engine off Using a multimeter, select volts-dc on the selector switch, then put the red lead to the positive and black to the negative. For a fully charged battery the reading should be in the ...

Fuse box is good on a Honda, choose the terminal where the source cable is connected directly to the battery, be sure to use an in line fuse (30A) on your wire. Use #10 wire to connect your accessory to the terminal.
