How much voltage comes out of a 12v battery charger when its charging?

A: If you means for a car it would be 13,68 volts minimum. But what is really important is the amperes out of it that is what is needed to charge a battery and that can be as high as 100 200 amperes out of the generator. Once the car has started the battery is no longer necessary to run it the generator and the regulator will just do fine.

How much time to charge 3000mah battery?
The milli-amp-hours rating has nothing to do with the voltage. The rating should be something like 3000 mah at 12V or 3000 mah at 1.5V. One common 3000 mAh battery is 3.0 volts; another is 3.7 volts. A common camcorder battery is 7.4 volts. Some DeWalt tools use 12 V 3000 mAh batteries.
Can an automatic gate opener battery be charged by a car battery charger if there is not enough sunlight for the solar panels?
Absolutely. This is acceptable as long as your charger is built for the type of battery used, and the voltage is right. AGM, flooded, GEL, Ni-Cad, and Lead Calcium are typical solar batteries. This battery charger can determine which is which.http://www.bdbatteries.com/chargers.php?id=7Basics:Think of a battery as an electricity tank.Just like your hot water heater (a water tank) it cares not where the power comes from.The hot water heater only requires water at the right pressure (voltage) to fill the tank, and not burst it. The rate at which the tank is filled (aka size of the hose) is irrelevant to ability to fill it up. However, the size of the incoming hose has everything to do with how long it takes to charge or discharge the tank.How To:Now back to your problem. Assuming your system is 12 volts. Your solar panels are one hose into your power tank at roughly 13.1 volts. The max charging rate for that system if 14.4 volts. The hose isn't as big as possible coming from the solar panels, and when there is no amps (water) coming down the wire (pipe), the battery (tank) is left under charged. To augment the power production, simply hook up any battery charger, the higher the amp rating on the charger, the faster it charges the battery.Neat trick:Jump start it with your automobile for 30 minutes. Drive to the gate, without shutting off the vehicle, attach the jumper cables to the battery Positive and the frame. The alternator has a rating of between 80 and 150 amps :) it can charge an 80ah battery in under an hour.Source: http://www.bdbatteries.com
Why negative voltage is used in BTS in GSM system?
Because 2 terminal comes out from the battery and through red wire we ground the +ive terminal so that possibility of noise interference will get zero....noise occur only in the +ive terminal.....thats why we use -ive voltage.
What band is low voltage?
Less than or equal to 1KV comes under Low voltage.
What Type of current that almost all electronics devices use?
The question is much too vague. Electronic devices can be designed to allow for direct or alternating current. Examples are your home DVD player plugged into the receptacle which is 120 volt alternating current and your ipod which uses battery direct current power. Small portable devices are usually direct current (battery power ). The plug that comes with such devices is for charging the battery. Or the device may internally rectify the alternating current and turn it into dc power.
Can you leave a trickle charger on a car battery for 5 months?
Yes, that is the purpose of a trickle charger. Just make sure it is an automatic charger that comes on when needed and then stops charging when the battery is fully charged. You can leave it on a battery for years if need be.
Please explain the charging circuit in automobile. 1. How does the charging light comes on when ignition switch is turned on 2. How charging light comes on when alternator is not or less charging?
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
What is the battery light on for on your Chevy Astro?
The battery light comes on when the charging system voltage drops below 12V. If your light is on all the time, have your charging system checked because it probably is not charging the sytem.
How do you know when an alternator is going bad?
Battery fails to charge, alt light comes on, sometimes only at low revs. Check with meter shows low or no charging voltage (close to or less than battery voltage) voltage does not increase to charging volts with engine revs increase
Does an iPad need a battery charger or something like this?
Yes, it comes with a charger.
Does the 3ds come with a charger?
Of course - it would be useless if it didn't! It comes with a normal mains charger and a new charging stand.
Why does the battery light go on and off in my 2002 Monte Carlo. Every time the battery light comes on the voltage drops. When the light goes out the voltage comes back. What could be wrong?
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt.
Does PSP go have a charger or battery?
The PSP-Go has an internal (nonremovable) battery and comes with everything you need to charge it when needed. Average battery life is ~6-10 hours depending on what you are using it for.
Where can I get the best car battery charger possible?
The Deltran Supersmart Battery Tender is the optimal choice in battery chargers for cars. It switches from a full charging mode to a float charging mode to ensure that battery is kept at maximum, it has a reverse polarity protection to ensure the user cannot be harmed, and it comes backed by a 10-year-warranty. You can buy it on amazon.com for approx. $43.
How do you change the pulse r71 battery?
You cant it comes with a charger
Why does the battery charging light don't go off after starting the engine of my 1983 Toyota Corolla?
Have the charging system checked. The light comes on when there is a charging system problem. it may be a battery, alternator or a battery problem.
What is wrong with your car if your voltage light comes on and it sputters then tries to die when you hit about 15 mph?
Sounds like the car is running off of battery power and the battery is very low on charge. The charging system has failed.
