No. Parallel wiring just gives the current more choices of where it can flow. What matters is the number of resistors in the circuit.
The batteries are over the counter watch batteries and they last twice as long as the battery put into the walker
The cell that lasts the longest will have the most batteries in parallel or serial.
It depends how they are connected. If the terminals of two 12 volt batteries batteries are connected to the same circuit (in parallel) then there is no change in the flow of current- it will just last for twice as long a time. But if two opposing terminals of the batteries are connected to each other first and the free terminals then connected to the circuit (in series) then there would be a total voltage of 24 volts and twice as much current would flow. The two batteries would last for the same length of time as one battery on its own.
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.
If the batteries are connected from + (positive) to - (negative) then the batteries are connected in "series". If the batteries are AA (1.5v each), then the resulting voltage of the two connected in series will be 3.0v. If the batteries are connected + to + and - to -, then they are connected in "parallel" and for the same batteries the voltage would be 1.5v, but would last twice as long as one battery by itself. A truck battery system is two 12v batteries connected in series (+ to -) to give the truck a running power of 24v.
Putting batteries in series will up the voltage of the entire circuit. Certain things need higher voltage, so you put your batteries in series. Putting batteries in parallel will not up the voltage, but will let the current last longer. Watches would be more of an example for that. You want watch batteries to last long.
If you want any batteries to last longer then put the batteries in your fridge and that helps them to last longer!!
If more ampere-hours (or CCA) are required, two (or more) new and identical 12-volt batteries can be connected in parallel. If you connect two 12-volt batteries in parallel, and they are identical in type, age and capacity, you can potentially double you original capacity. If you connect two that are not the same type, you will either overcharge the smaller of the two, or you will undercharge the larger of the two. Connect them in parallel, that is + to + and - to -.
Frozen batteries last longer unfrozen batteries.
The first lamp will go out. ANSWER: any lamps in series the first or the last if unscrewed will cause all lamps to extinguish no matter whether the source potential is in series or parallel
Lithium batteries can last one and-a-half to two times as long as NiMH batteries.
they are bigger
