Can a motorcycle battery charger be used to charge a lawn tractor battery?
If both batteries are of the same voltage (12 or 6) yes, you can use the charger. make sure that they are of the same voltage.
How much volts can a AA battery supply?
AA zinc and alkaline batteries normally provide 1.5 Volts when they are new. The voltage will drop as the battery discharges. Rechargeable batteries using NiCad or NiMH technology deliver 1.2 Volts when fully charged. Again, the voltage will drop as they discharge. It is this small voltage difference that can make rechargeable batteries less effective for some voltage sensitive applications,
How many batteries will it take to make 120 volts?
It depends on the terminal voltage of the batteries, as different types of battery (or, more accurately, 'cell') have different terminal voltages. A car battery has Approx 12 V, so ten of them.
What kind of voltage does a battery make?
depends on the battery type and chemicals used in it. for example lithium battery is 3v,lead acid is 2,zinc carbon is 1.5v,and....(remember these are per cell). and by the way batteries always give you DC (direct current) voltage.
How do I wire 3 batteries to make 24 volts?
That depends on what voltage your batteries are,
What will happen if you connect a similar make capacity and voltage battery in parallel with an existing ups battery do you need to change the charging unit to charge these batteries?
In parallel no, the voltage is the same the amps double. If hooked up in series the voltage would double and then the charging system would need to be changed.
Can you make a bulb glow more brightly by adding a second battery?
Yes, two batteries will make a light bulb brighter than one, provided that the batteries are placed in series. The brightness of the bulb is determined by the voltage, and placing two batteries in series rather than just using one increases the voltage.
How do you make a 6 volt battery into a 12 volts?
That is Impossible. You can however make two 6 volt batteries into a 12 volt system by wiring the two 6 volts batteries in Series. You will then have an output voltage of 12 volts but the amperes will only be what one of the batteries have, In other words the volts will double but the amps will stay the same as if you only had 1 battery connected.
Can you charge batteries with a different mAh rating?
You can charge batteries with a different mAh rating if the charger is designed to handle them. You need to make sure of this, because Ni-Cad battery full charge state is not necessarily voltage dependent, but rather is dependent on detection of a change in voltage slope. If the power supply is not properly designed, you can overcharge the batteries, damaging them.
Drive 1991 Honda and the battery keeps on dying can anyone tell me why please help?
how old is the battery? batteries have a life of about 3 years. check the alternator, the voltage regulator,and the battery check the battery cable terminals for cleanliness and make sure they are tight
What kind of battery do you use to make a light bulb glow using wire and battery?
Any sort of dry battery will do this, you just need to match the required bulb voltage with the battery voltage. Most small dry batteries give 1.5 volts, the square shaped ones give 9 volts, and there are bigger ones used for lanterns and large flashlights. The bulb should have on it the required voltage, if it is say 3 volts you will need two batteries in series (connect them positive end to negative end of the second) or you can make a string in series, you just get number of batteries x 1.5 volts. If it is a car bulb these operate at 12 volts, you will need a car type battery for these.
How do you wire 2 batteries together to make 24 volts?
Do you mean 2 x 12 volt batteries? If so:Wire 1st battery's + to load, wire it's - to the + of the 2nd battery.Wire 2nd battery's - to the other side of the load.**********************************************There are two basic ways to wire multiple batteries together, in "Parallel" or in "Series".PARALLELWiring two batteries which have the same output voltage in "Parallel", the output voltage of the combination stays the same but the amp/hour capacity of the combination is equal to the sum of their individual amp/hour capacities.Wiring: Battery 1 Positive to Battery 2 Positive and Battery 1 Negative to Battery 2 Negative is Parallel wiring, retaining the voltage rating of either one of the batteries.WARNINGIt is not a good idea to wire two batteries which have different voltage ratings in parallel because the one with the higher voltage will immediately send current to the other one with the lower voltage to try to make their voltages both the same. The very high current which will flow between the two batteries is likely to make the batteries get very hot. IF THEY ARE CAR BATTERIES THEY COULD EXPLODE!SERIESWiring two batteries which have the same output voltage in "Series" makes their combined output voltage equal to the sum of their individual voltages but the amp/hour capacity of the combination will be no greater than the amp/hour capacity of the smallest battery of the two.Wiring: Bat 1 Positive to Load, and Bat 1 Negative to Bat 2 Positive, then Bat 2 Negative to the other side of the Load is Series wiring and the total voltage of the combined batteries is the sum of both individual voltage ratings.So, assuming you want to get 24 volts out of two similar batteries, you could wire two 12 volt batteries in series.NEVER OPERATE A 12 VOLT ELECTRICAL SYSTEM as in CARS or most BOATS with 24 VOLTS. YOU WILL BURN UP YOUR COMPONENTS AND SOME WIRING.Common Flashlights are simple examples of series wiring. Flashlight batteries are usually 1.5 volts whether they are AAA, AA, C or D size. So flashlights with with 1 battery are operating at 1.5 volts, 2 batteries are 3 volts, 3 batteries are 4.5 volts, etc.
