Yes, it simply has less capacity.
Many digital cameras use a 6V battery. They're also used in blood-glucose meters, blood pressure cuffs, flashlights, and lanterns.
Most riding mowers have a 12-volt system and require a twelve volt battery. Mower batteries are much smaller than regular car batteries, and can be purchased for about $25-$40 at Walmart or auto supply stores.
If the bulb is a 40 watt, 120v bulb, you would need 20 6 volt batteries wired in series, or 80 (!) 1.5 volt batteries. 1.5 volt batteries are AAA, AA, C, D, etc. Since this solution is rather extravagant, try finding a light bulb made for an RV. These typically run off of 12 volts, and you can get a single 12 volt battery, or 2 6 volt batteries, to run this bulb.
Use 8 gauge wire.
The answer is going to depend on the size of the battery and what you are mowing. 12-volt batteries provide 30 - 40 minutes of mowing time; 24-volt mowers last 40 - 75 minutes; and 36-volt mowers run for up to 90 minutes. If your lawn is thick, lush or tall then the charge may not last as long.
If you connect an alternator that has been designed for charging a 12 volt battery to any 24 volt system in an attempt to charge its batteries, that alternator will not work because of either of two different reasons:if the 24 volt battery is completely dead or flat the 12 volt alternator will not be able to charge it to much above 18 volts. That is about as much practical use as having a flat 24 volt battery!if the 24 volt battery is not "flat" but has a voltage that is in its normal range - between about 23 volts and 27 volts - the 12 volt alternator would not do anything because its output voltage cannot go high enough.Some more facts:12 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 13.5 and 18 volts and an output current that could vary between zero and about 40 or 50 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of the alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 12 volt car battery. A nominal 12 volt lead-acid type car battery that is flat has a voltage of about 11.5 volts or less. One that is fully charged would have a voltage of about 13.5 volts.24 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 27 and 36 volts and an output current that could vary between zero and about maybe 80 or 100 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of its alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 24 volt vehicle battery. A nominal 24 volt lead-acid type battery that is flat has a voltage of about 23 volts or less. One that is fully charged would have a voltage of about 27 volts.Only in the instance where two 12 volt batteries were connected in series to produce power for a 24 volt system, could a method be devised to use a 12 volt alternator to charge the batteries independently.
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
You should charge the battery with the proper battery charger. The battery charger should list what types of batteries, voltages, and charge rates (amps) it is compatible with. Make sure this matches the information on the battery to be charged. Using the incorrect battery charger can cause battery explosion, leaking, or fire.
amps*volts=watts 40 amps *12 volts= 480watts watts/volts=amps 480watts/110volts=4.36363636amps So you need a 110 volt generator that can produce about 5 amps as a bare minimum. To take into account system heat loses that occur when converting power consider doubling it to be safe. (this is over kill but the advantage is that your generator is not working at full capacity at all times)
In North American homes, new homes are prewired to use a 40 amp circuit. A 40 amp two pole breaker in the distribution panel protects a #8 three wire cable. This cable connects the 240 volt supply to the range and oven.
The formula for amps is I = W/E. Amps = 40/240 = .17 primary amperage. For the secondary amperage I = W/E. Amps = 40/24 = 1.7 amps.
Yes you can but the electrical code does not require it. To use one where it is not requested to do so is just adding to the over all expense of the project.
