Connect 4 in series.
If it is in your car then no, why do you have a 6v battery in your car in the first place it should be a 12v.
There is no answer to this question. It could be anywhere between 2.5V and 12V. If you connected them in series the answer would be 20.5V, in parallel the higher voltage battery will discharge into the lower rated cells, the resultant voltage is dependent upon the internal resistance of each of the batteries. In practice you wouldn't do this, so it's either a mistake or trick question. www.powerinspired.co.uk
If you connect bulbs in parallel across a given voltage supply (eg household mains supply) then they will all draw their rated current and will glow at their rated brightness. If you connect the same bulbs in series then they will glow very much less brightly. This is because the resistance of a bulb's element is also related to the power dissipated in the element. A bulb's element is rated for operation at a particular voltage. You can certainly connect two 6v motorcycle bulbs in series, and connect them to a car battery at 12v, and the two bulbs will be just as bright as they were when individually operated from the motorcycle 6v batttery. However if you connect two 6v bulbs in parallel and then wire them to a 12v car battery they will only glow brighter for a fraction of a second and then ... pop. You will have overheated the elements beyond their designed power handling capability.
Substituting a 9V DC power supply for a 6V DC supply is generally not advisable, as it can lead to overvoltage conditions that may damage the device designed for 6V operation. Components may overheat or fail, and the device may not function correctly. Always check the specifications of the device to ensure compatibility with the power supply voltage. If a 9V supply is required, consider using a voltage regulator or a suitable step-down converter to safely reduce the voltage to 6V.
You can't run a 6V 75A (450W) light off a 12V 2.5A (30W) battery for any significant length of time. That battery is grossly undersized. I think that's supposed to be "0.75A" instead of "75A." I found a 75-watt light bulb on the internet, but 75 amps? You could weld with that much power. And I like the answer right below this one best: just wire two of these bulbs in series. The answer is simple by using the formular called OHM's LAW (V=IxR) The 6V,3/4 amp bulb has (approx) 8 ohms resistance which 'drops' the 6 volts across it. At the same current (thru the SERIES circuit) you need anothe 8 ohm resistance. Unfortunately, the bulb dissipates 4.5 WATTS of power, the same as your 'extra' resistor will have to handle. (Rather WARM!) The easiest trick to do would be to put two 6v bulbs together in series, this will put your 'extra' resistor (the second bulb's filament) inside of a protected glass shell. The second bulb will not waste any more power than the resistor, and will give you twice the light.
It will glow VERY BRIGHTLY for a few seconds - and then burn out.
No you should not do that. It will damage the battery and the battery will explode.
The battery is a 12V car battery.
If the machine is designed to run on 6v and you use two 6v batteries instead of one, then . . . -- If you connect the two batteries in parallel, then they will last twice as long between recharges as one battery does. -- If you connect the batteries in series, then they will definitely overheat the motor, and possibly destroy it.
A 6v motor might not run at all on a 4.5v battery. Whether or not it does, it's likely to discharge the battery rather rapidly. A series resistor will help the battery last longer, but will make it even less likely that the motor will run at all. You're better off taking some time to find either a 4.5v motor or a 6v battery.
The largest battery in size is a 6V or 6 Volt.
No, it is a disposable battery.
No, you cannot use a 12V 7Ah battery in place of a 6V 7Ah battery without modifications. The voltage difference would likely damage devices designed for 6V, as they are not built to handle the higher voltage. If the device requires a 6V supply, it is crucial to use a battery that matches the specified voltage to ensure safe and proper operation.

Yes, most leds will run on a 6v battery. Just look at the required voltage and make sure you don't exceed the maximum voltage. If the voltage is to high, find the correct resistor.
You don't.
Yes, you can recharge a 6V 500mA battery with a 6V 300mA charger. The charger with lower current (300mA) may take longer to fully charge the battery compared to a 500mA charger, but it should still work. Just ensure you do not exceed the voltage rating of the battery.
