As far as the battery issue goes - one other thing to check is the battery connections. Open the hood and look at the battery connections and feel with your hand if the two wires (positive and ground) are fixed securely to the terminals. A loose cable can cause intermittent problems because the normal motion of the car (going over bumps, etc.) can move/jog ...

You should throw it in the regular trash. When possible, it is almost always preferable to dispose of something in the "solid" trash rather than adding it to the wastewater (down the drain). While wastewater goes through elaborate processing to remove contaminants, if a thing can be disposed of by other means, it is better to do so rather than adding it as ...

After jump starting the car, turn on the head lights, heater, rear windscreen heater etc. if they all operate correctly, e.g the lights are full brightness and the heater fan sounds like it is running at normal speed, then your alternator is fine and the problem is your battery. If the lights are dim, then the fault is the alternator. After totally ...

maybe you should consider replacing the battery / is the general case when the battery light lights ups

You seem to have several concerns here, so let me try to address them one at a time. You are worried about the car starting up properly. Since the engine would not turn over when you tried to start it, then it started right away with a jump start, it sounds like it was only the battery you need to worry about. Either you left a light on or something else ...

Two reasons: To reduce the possibility of short-circuiting the battery by removing the connection to 'ground' To make sure everything is switched off and unable to function while you're working on it. You don't want, for example, the electric fan to suddenly kick in while you've got your hands in there...

One other thing that happens when a multi-cell battery is completely discharged is that one of those cells may be driven into reverse polarity. This will have a drastic effect on a battery's life. Most will tolerate this only a few times, some types only once.This from Wikipedia:Damage from cell reversal Subjecting a discharged cell to a current in the ...

What I would do is first is put battery on charge over night if battery was drained to much then alternate won't 0rod7ce quite enough to charge it.

There are a few scenarios that can cause battery charging issues. First check the connections. If it is serviceable check the water level. If it is low, charging may have overheated and damaged the plates. If the battery was a newer technology AGM type (advanced glass mat technology) and it was charged with a older style conventional charger the battery may ...

I went back to the garage where the anti-rust system has been installed and the guy confirmed the problem was the battery terminal connection that got loose. I don't know if it could have been something else but that solved my problem.

I would recommend just going to your local auto store and getting a terminal brush and battery cleaner. I have not personally used baking soda so I can't say for certain how well it can work but I have seen people use Coca Cola. While it does clear away corrosion buildup it leaves residue behind. I'm sure people say "Well that's why you clean it afterwards", ...

The BYD can charge at every public charging point, excerpt CHADEMO ,Combo And superchargers, The last one is for Tesla only.... the plug in the picture is the DC plug, But the car has also a AC connection Update: here in Europe it can charge at Public type 2 mode 3 chargers (doesn't have the name mode 3 in US) In US it maybe charge on AC in a different Way ...

actually you will read only the first 2 digits from this code "G5B6882230170" first digit means the month starting with A -> January and ending with L or M (as some of the manufacturers omit the letter I) for December and the second one "5" is the year of production.

Do they need about 3000W for starting? (About 250 amps?) 250 A is on the low side according to the Bosch Automotive Handbook (8th edition), which indicates that the primary current of the engine starter can be as high as 1000 A for passenger cars. Quote from the book (emphasis my own): The relay current (approx. 30 A for passenger cars to approx. 70 A ...

You can have a good alternator and still not charge the batteries if the connections are corroded in anyway or a battery clamp is loose or cracked. Also check the fusible links there should be one in line between the alternator to starter to battery circuit but if its pumping out 14 volts at 2000 rpm and wont idle for long afterwords then i suspect the ...

It pays to get a Solar brand battery tester which uses a conductance test to evaluate how many CCA is left in your battery. That way you can decide when it is time to let go of the battery.

Normally if alternator is good, car won't die even without battery. I suspect alternator. I suggest you to buy a battery charger and charge battery and buy a Solar BA7 tester to test how many CCA are left in your battery. After eliminating battery problem, go ahead and buy an alternator.
