Can 3 .55V solar cells charge a AAA 1.2V battery The maximum amperage of the solar cells is about .3 amps 300mA in direct sunlight. A?

Yes, you are creating enough power to force power into the battery or charge it.
Do be careful though, you would probably want a resistor in there to limit the voltage the battery sees or you will burn it out. I would like to see 1.5 - 2.0 volts charging rather than the whole 3.55.
The easy way to do this is to charge 2 batteries at once. Set them up end to end, so the positive of one touches the negative of the other. No put charging leads to the other 2 terminals on the ends. Each battery will receive 1.75 volts at .3 amps or 300mA.

Why the dry cell work when kept in sunlight?
A dry cell works when kept in sunlight because it is comprised of a metal called electrode or graphite rod. The sunlight helps the cell to maintained 1.5 volts and stored a charge of one coulomb.
Will a sharp metal point with a small radius curvature store a large or small amount of charge?
There are two limits to how much charge a perfect conductor can store. One is determine by its area and has nothing to do with sharpness or radius of curvature. Thus, a larger area can store more charge than a smaller area. However, the other limit on the maximum stored charge is when the potential reaches the breakdown voltage and then an arc occurs. This breakdown voltage is easier to achieve when the object is sharp and thus ultimately it will indeed store less charge.
What is the charge of a nuetron?
the charge of a neutron is neutral.
Atoms have a net charge of zero true or false?
True. The atoms have a proton which has a positive charge and there are same number of electrons with a negative charge. Those two charges cancel each other out and the charge becomes zero. The neutrons do not have any charge.
Subatomis particles that no has charge is?
nuetron has no charge. its symbol is - O
How long would it take a 200 watt solar panel to charge a 12V deep cycle battery?
A very long time. I would guess 48 hours of sunlight at the very least. Even that may not be enough to fully charge the battery. It really depends on how much amperage the solar panel is putting out.
How long does it take a car battery to charge?
Depends on the amperage you are applying to it. Read the charger manual.
How long does it take to charge a 12V car battery?
Depends on the amperage you are applying to it. Read the charger manual.
Is sunlight used to charge batteries?
It can be used with a solar battery charger.
What should battery charger needle read?
That depends on the battery, and the charger. my charger has different settings for higher amps to give a faster charge or jump. A fully charged battery will show 12.6 volts. The charger will read it's maximum amperage if the battery is totally discharged. A fully charged battery will read 12.6 volts with a digital DC volt meter. If it reads 12 volts it has less than 25% charge.
Can a low battery cause starter not to engage?
Yes. Without sufficient charge, the starter will not have enough amperage to crank.
How long does it take charge a 12v motorcycle battery with a 12v car charger?
Depends on the amperage of the charger. A 10 amp charger will charge it in about 1 hour.
Can you charge a 7.2 volt battery with a 6 volt battery charger?
most likely the trickle feed will be so low that you'll never achieve a maximum charge on the battery.
How can i charge my car battery from home using a laptop charger?
Sorry, but that is not likely to work. Both the voltage and amperage provided by a charger for a laptop battery will not be correct for a car battery. It is likely that you will damage the charger.
What is the lowest voltage for car battery and still be good?
The lowest voltage a battery can drop to during cranking while still starting the car is 9.6v. You can tell a battery's state of charge by the voltage (12.6v is fully charged, 12.0v is low), but the way to tell if a battery is bad is to look at how the voltage changes under load. Most battery testers put a load of half the cold cranking amperage indicated on the battery and look for the voltage to drop below 9.6v, in which case the battery is determined to be bad. Another way to do it at home is to charge the battery at high amperage (can be done by revving the engine slightly and turning off electronics) and, using a voltmeter, look for the voltage to be above 15.5v. This indicates a lower amperage charge than desired and also that the battery should be replaced.
Why cellphone battery need initial charging?
Rechargeable batteries are generally stored and shipped with no charge. This allows for a longer battery life. Fully charging the battery the first time will give you the best results for maximum charge and battery life.
What is the best motorcycle battery charger?
Any 12 V battery charger will charge a motorcycle battery. But it is best to get one with low amperage such as a 4 to 6 amp battery charger. You can use a trickle charger to keep the battery charged on my motorcycle during storage.
