It was like I disconnected the battery, no power whatsoever. I got out and checked the battery and everything looked fine. Suddenly the running lights turned on again. I got back in and turned the key and instantly lost all power again. Sat there for about 5 minutes and it suddenly came back and has been fine since. I have no idea what is going ...
Re: Offgrid-House: Battery bank suddenly losing power rapidly? Use an accurate volt meter and check the voltage at each cell/battery. My guess is you have a poor electrical connection (only 1 battery string is carrying current), or a bad cell (shorted cell taking down bank, open cell preventing a string from charging/discharging).
Bonjour à tous, J''ai déjà posté mes mésaventures sur ce forum, mais il me semble que mon message a disparu, pas moyen d''en retrouver la trace ! :-s Donc brièvement pour remettre le problème en contexte, la situation est la suivante : Ma clio II de 220.000 bornes ne capte aucun signal quand on ess...
Check The Battery. When you have used your battery for a long time, about over three years, it might fall victim to the aging problem. Gradually, its connection becomes loose, so the battery power supply cannot …
Importantly, there is an expectation that rechargeable Li-ion battery packs be: (1) defect-free; (2) have high energy densities (~235 Wh kg −1); (3) be dischargeable within 3 h; (4) have charge/discharges cycles greater than 1000 cycles, and (5) have a calendar life of up to 15 years. 401 Calendar life is directly influenced by factors like depth of discharge, …
There IS NO surplus of electrons on the battery. Moreover, if some wayward, rebellious, electron were to try to venture across to ground, the battery would now have a net positive charge, and the electron would be pulled back in, or immediately replaced with another one from ground. Either way, no net current can flow to ground.
In a NiCad battery the charging reaction is endothermic, but the discharge reaction is exothermic. So when charging it actually sucks heat from its surroundings and stays cool (until it is full and the reaction finishes), while during discharge it produces heat and gets hotter than you might expect. NiMH batteries do the opposite - they get hot while charging, but …
I went for a ride today with my Juiced Cross Current bike and my battery suddenly quit. My normal ride is around 15-17 miles on flat pavement. I set my bike at level 3 and average 25MPH. My battery meter was slightly less than half and my volts were reading 49.2. The screen suddenly went blank and there was no power. I could not turn on the ...

Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

Have had my 2016 SRX and recently battery went completely dead with no warning. I have had battery problems in other cars. You get a warning? Some light on the dash? I see the red battery symbol comes on along with all the other lights and goes off as well. I checked the battery and it shows, on my multimeter, that it is dead.
However, the next morning the car had no electrical power again, which was a clear sign the battery died. A quick battery swap and my car has been running flawlessly since. If your battery has a few years to it and is out of warranty, I would recommend you try the same thing as I did. Give it a jump start or a recharge and see what happens. The ...

During my auto scans using VCDS, the battery voltage is reported as being 11.9-12V. VCDS battery testing shows the state of charge to be 70%. My question is this- does VCDS report the actual voltage reading at the battery terminals, or does the voltage get regulated somewhere in the car to a nominal 12V and this is what is reported?
So, even if a single potato could somehow produce hundreds of milliamps of current, there is no way for a chemical reaction to occur simply by inserting a USB plug. No chemical reaction means no current. Finally, electronic devices typically require a current and voltage that are well regulated in order to charge properly. For example, USB ...
As the battery is discharged, ions move from one electrode to the other, and the chemical reaction proceeds until one of the electrodes is used up. Thinking about two batteries next to each other, linked by one wire-- there is no voltage between the two batteries, so there is no force to drive electrons. In each battery, the electrostatic force balances the chemical force, …
A car battery does not die slowly, it dies suddenly. When a battery dies, it is because the chemical reaction inside of it can no longer create the electrical current needed to power your car. This can happen for a number …
In thermal runaway, the battery cell temperature rises incredibly fast (milliseconds). The energy stored in that battery is released very suddenly. This chain reaction creates extremely high temperatures (around 752 degrees Fahrenheit / 400 degrees Celsius).
