The battery is toast. Save yourself potential serious injury. Buy a new one. If the battery has been dead for eight months...it is pretty much a goner.

This shouldn't be too crazy. You will probably need a multimeter to test things. (If you watch the specials carefully, there is at least one tool outlet that gives these away as special coupon deals I would start the journey with the service manual. It's available here. Check out section #6, electrical. Your system is pretty simple. A couple of ...

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 ...

The difference is smarts. A trickle charger provides a constant current all the time. It does not know whether the battery is charged or discharged. A battery tender is smart. It will charge the battery only when it needs charged. After it's done charging it will shut off and monitor the battery state. When it sees the battery get to something like 80% (...

You're probably better off starting and driving the car everyday or leaving a battery tender on the car. Some cars learn and store values like idle, etc... When the battery is disconnected it loses these values. There's no real harm in disconnecting the battery, just some inconveniences that may or may not require scantools to resolve.

The CCA on a battery indicates the Cold-Crank-Amps of the battery. It means the amount of amps the battery is able to deliver in 0 degree Celsius . Higher CCA means better starting ability of the battery. I did some research online and I found out that you can use anything more than 130CCA on your motorcycle without any issues.

Calculate it yourself: If you have a full 66Ah battery, it will be drained within 66Ah/22A=3h. BUT: A battery degrades over time, after a few years, the capacity isn't 66Ah any more. An almost empty battery isn't capable to deliver the same max. current as a full battery. If it's almost empty, you could have problems staring your motor. This is even more ...

As the other user stated, the only thing it'll affect is the ECU, stuff like Idle speed, or different settings will be reconfigured, my only word of caution is when you put the battery back in and turn the car on, let it idle for a while so it can reconfigure everything such as idle speed so it doesn't run as rough.

Should be fine. It will reset the ECU after a couple minutes (when the capacitors loose their charge). The shop will likely disconnect the battery while working on the car. Leaving the battery sit for a couple months should be fine as long as it was good to begin with. A weak battery may not last that long.

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.

In my experience batteries that are not regularly charged will be dead after about 3 months. A car battery after sitting idle for a year most likely not accept a charge. Time to replace the battery.

Since the car sat for a year, it is likely the battery is dead. If the battery terminals are corroded, they could also be preventing the alternator from charging the battery. I would try starting the car with a known good battery, and/or taking the dead battery to a parts store to be tested, as you may still be able to recharge and use it. Next time you park ...

There are too many possibilities when it comes to draw. The compressor clutch could be staying on, alternator voltage regulator, a glovebox light, radio, computer etc... You're going to need to use an inductive amp probe and a multimeter to voltage drop the fuses. I'd avoid disconnecting battery terminals to hook an ammeter inline with the battery ground. ...

The "strong smell, like sulfuric acid" is in fact sulfuric acid, which is the acid component in a lead-acid battery. If it's coming out strongly enough for you to smell, the battery is dangerous. Recycle it and get a new one!

Sounds like a dead alternator. I had that same issue years ago with an '89 VW fox. The reason that everything was slowly shutting down is because you driving on the battery alone. As the battery was getting drained the voltage was falling below the affected component operating threshold voltage and they would begin to cut out. The process would take about ...

I think there may be one or two things happening here (but this is more of a gut check than anything): The serpentine belt is worn out, causing the battery not to charge the battery correctly. Usually if the belt is getting worn out, it will cause a chirping sound when it slips, but if the belt is worn and glazed, it could be slipping without you even ...

Recheck the wires that connect the battery and the alternator. Do you get power anywhere else in the car? Lights? When you turn the key? Your new battery could be bad. If so, you could try jumping the car, and it should keep running if the alternator is good. If it starts but doesnt keep running when you disconnect everything, then alternator is bad. If it ...

If there truly is no liquid in it, you cannot charge it. Attempting to will have no effect. But if there is some, and you try to charge too fast, heat and explosion hazards are produced.

After referring to page 26 of the owners manual here, I have confirmed that the large black wire coming from the negative black terminal should be grounded to one of the bolts that mount the starter motor to the block.

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 ...
