Can I use a 9V power supply on a 6V device?
Rob said: Generally there’s a big tolerance in these things so you should be OK with 9 volts. Recommend trying it with 5 volts first and using that lower voltage if possible.
Can I charge 6V battery with 9V charger?
Yes, you can, but you need to drop the voltage so that the 6V battery does not over charge. Either a resistor or an Inductor with enough resistaance will do the trick. But you need to know the size of the battery, and the current that the charger pushes out.
Can I use a 9V DC adapter in place of 6 AA batteries?
It depends. 6 AA batteries, if connected in series, will produce slightly more than 9 V when new, dropping to 6 V when depleted. They will output up to several amps for short periods. Their output voltage is not regulated, but it is pure DC with no 100 or 120 Hz ripple.
Can you charge a 7.4 V battery with a 9V charger?
No. But you need a charger designed to charge a 7.4 volt lithium battery pack and designed to run from a 9 volt power supply. It won’t “just work”.
Will 9V work 5V?
The 5V supply and 9V need are close enough that it may work, for a while. In technical terms, a lower voltage can cause transistors to not turn on all the way, which produces waste, which produces heat that can burn them out.
Can I use 5V adapter for 6V?
The short answer is No. A 5V, 2A adapter gives 10W of power and the 6V,1A gives only 6W.
Can I use a 12 volt charger to charge a 6 volt battery?
This will run your battery dry and create a thermal runaway scenario, which is very dangerous. Again, some people use a 12V charger to get their 6V battery jump started, but it is never advisable to use a 12V charger to try to fully charge your 6V battery.
Can you charge a 9V battery with a 12V charger?
Similarly, you can charge a 9V battery with a 12V charger, and we show it in more detail below with Lithium-ion and NiMH batteries. The 9V li-ion battery is made of two 3.6V cells lending it a nominal voltage of 8.4. To safely recharge it you need a voltage source of 8.4V.
How many amps is 9V?
A standard 9V battery has about 400-600 mAh capacity. In the most basic terms, these batteries can supply about 500 milliamps for one hour before being “dead”.
Is 9V the same as AA?
Calculating Energy in an AA Battery A single Energizer AA, or E91, is rated for just under 3000 mAh at 25 mA drain. For this calculation, I picked 25mA because that is the nominal current draw for a 9 V. Obviously, that calculates as 6X a single AA and just slightly more than 4X a 9V battery.
Can I charge 9V battery?
The 9V li-ion battery is made of two 3.6V cells lending it a nominal voltage of 8.4. To safely recharge it you need a voltage source of 8.4V. It will automatically stop the charging once each cell voltage reaches 4.2V and the battery is full. Next, this is how you charge a 9V NiMH battery with a 12V charger.
Are all VDC power supplies the same?
Although a typical desktop VDC output power supply will offer 3.3, 5, and 12 volts of DC to meet the various demands of a PC system, not all VDC output power supplies are equivalent. Keeping this in mind, one must take careful consideration when designing a PCB based on power requirements.
Can I use a 6V DC motor with a 9V power supply?
In fact this will increase the speed of motor but with little bit of production of heat. So there is no risk of using 6v DC motor with 9v of DC supply. Same as with the motor, if you provide 6 V to 12 V motor, your motor will run on half of its rated speed and the torque will also reduce.
What is VDC and why is it important?
What Is VDC, and Why Is It Important? VDC refers to volts of direct current, and it can come from either a battery or a power supply that converts AC (alternating current) into DC. As its name implies, DC flows consistently in one direction, and we typically supply it via conductors (wires).
What is the difference between a switch-mode and linear VDC power supply?
In a switch-mode VDC power supply, a rectifier produces the DC output voltage. Regarding size, a linear VDC power supply is usually larger and heavier. The size differences of these will often determine which is best for your particular design.
