What type of charger do you need to charge 6 volt 2 mph kids motorcycle battery?
You need a 6 volt charger. When you buy a charger look for one that monitors the voltage level of the battery while it is charging and when the battery is fully charged it will turn off. Indiscriminate charging of a small battery can easily destroy it. Being left on the charger too long can boil the electrolyte out of the battery. A battery can not recover from this action and it will need to be replaced.
How much does it cost to recharge a cell phone battery?
Only running cost is the cost of electricity consumed to charge the battery through a charger. How many units of electricity is consumed will depend on the capacity of battery, efficiency of the charger (and so losses of energy in the charger in form of heat and radiation). You can estimate the power consumed by the voltage and wattage rating of the charger and how long it takes to charge the phone battery fully. - Neeraj Sharma
How long time will be taken by the 12V 7Ah charger to charge a 12V 22Ah battery?
A charger designed for a 12 volt battery should not be used to charge an 8.4V battery. It is likely to damage the battery and in the worst case can cause a fire. There are some chargers that can be used with a variety of battery voltages and chemistries but unless you are certain that the charger is safe and effective on a different battery voltage, assume that it cannot be used.
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 does a cell phone charger drain a battery?
As long as the charger is connected to its power source it will take a small amount of power from that source (even if the phone is not connected to it), regardless of whether it is an AC "wall wart" charger or a cigarette lighter charger (although normally turning the car ignition off turns the cigarette lighter outlet off, so if it drains the car battery the car ignition switch may have a problem). If the phone is connected to the charger it may continue to take extra power even with the phone fully charged (I have a Tracfone that will drain my battery powerpack completely (if not connected to a charger its internal battery drains completely in less than 2 days even if I'm not using it at all -- this phone has something wrong in it). The real issue is now fast the charger is draining the battery. BTW, I am assuming above that you mean an external battery that the charger is connected to, not the internal battery of the cell phone itself (if this is the case I would say the phone is seriously defective as this would normally not be possible).
How long does a solar panel laptop last?
I did not locate a solar panel laptop itself, but there are solar panel laptop charger for the laptop battery. these will last many years and substitute for buying a laptop battery every year.
How many hours will a solar battery charger typically need of sunlight before I can use it?
Read the manufacturer's instructions. The unit is used to charge other devices using the sun. The unit itself doesn't hold a charge. How long it takes to charge other devices depends on what you're charging. This article offers a comprehensive overview and explains how to calculate the time various devices take to charge with a solar-power charger http://www.12voltsolarpanels.net/12-volt-solar-powered-battery-chargers A solar battery charger does not take a charge, hold it and then spend it to charge other devices. The solar battery charger is connected to the device and uses solar energy to re-charge the device, as opposed to charging its own self first. How long it takes the charger to charge another device depends on the voltage of the device.
What does a trickle charger do to a battery?
A trickle charger is a car battery charger that is designed to be left on a car for very long periods of time to re-charge that car battery by slowly adding charge to the battery.
How long should you charger a 7.2 battery with a 9.6 volt charger?
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
How long do you need to charge your car battery using an automatic battery charger?
If it is an automatic charger let it charge until the charger shuts off.
Can I charge a solar garden light battery on an ordinary charger?
yes as long as they are both of the same voltage it depends on whether it's low volate light
Can you charge a gas scooter battery using a car charger?
As long as it is a 12 volt battery you can if you set the charger on low.
Will hooking battery charger up backwards on boat battery damage anything?
Connecting a battery charger backwards to a battery will likely kill the battery, depending on how long the power is attached.
Can you use any car battery charger to charge a battery from an automatic car?
As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.
How long to charge a 12 volt battery on slow charge with a 30 amp charger?
I doubt the charger is putting out 30 Amps on a slow charge. need more info on battery and charger.
Does leaving a phone charger in the car drain the battery?
No, the charger pulls so very little power as to not be an issue unless the car was not run for a long period of time. It would take a very long time for the charger to drain the battery.
How long do you charge a riding lawn mower battery?
Depends on the output of the charger which you did not list. A dead battery can be recharged with a 10 amp charger in 3 hours.
