How Do You Charge A 12-Volt Battery With A 9 Volt Battery?

The short answer is you can not charge a 12 Volt Battery with a 9 Volt battery. If there is a will there is a way .. Lets assume your 9 Volt battery has enough capacity to power a circuit (lots o A/h Ampere Hours) , then you could build a device to make 13 or 14 volts out of the 9 Volts and charge the 12 Volt battery.

Can you use 9V for 12V?

What is this? When a pedal says “9 – 18V”, it means it can accept voltages anywhere within that range. That means you can use a 9V power supply, a 12V supply, or an 18V supply without any problems.

Can you charge a 12 volt battery with a 8 volt charger?

But, you don’t have to wait till you get a dedicated charger before you can charge your battery. You can use a 12 volt charger to charge your 8 volt battery. You can as well charge a 6-volt battery with an 8 volt battery charger.

What happens if you use a 12V charger on a 9V battery?

Only if the 12V charger is designed to charge a 9V battery. Not very likely. If it isn’t so designed, the battery will be overcharged even if you place a resistance in series to limit the current. It’s not a real problem anyway, since there isn’t a rechargeable 9V battery.

Can you charge a battery with a different voltage?

A higher voltage will cause too much current to flow during charging and reduce the battery life. Over charging a battery (too much current due to too high voltage) causes heat and loss of electrolyte in wet cells.

What happens if I use a 9V adapter on a 12V device?

Plugging in an adapter with a lower voltage would not generally harm the unit. But if the polarity is reversed then it probably would cause damage and that may be what has happened. It may just have blown a fuse.

How do I convert 12V to 9V?

To reduce a 12V circuit to 9V, place two resistors in series within the circuit. Find the difference between the two voltages (12V – 9V = 3V) to determine the total amount of resistance needed.

Can you charge a 48 volt golf cart with a 12 volt charger?

Golf carts typically use a 48 volt battery bank so a conventional 12 volt automotive battery charger won’t work. The 48 volt pack is generally made from 12 volt batteries in series it can be disassembled and the individual batteries charged one at a time with the automotive charger.

Can I charge my golf cart with a regular battery charger?

These batteries are designed to be discharged almost completely and repeatedly with low loss in performance. Golf carts usually come with their own charger, however a car charger can also be used to charge a golf cart. The trick is matching the voltage of the charger to the voltage of the batteries.

Can you charge a 48v battery with a 12v charger?

A 12 V battery charger can never charge a 48 V battery. A charger should at least have 12% more output voltage than the battery’s rated voltage. A 12 volt charger will not exceed the 48 volt battery cell overvoltage and not deliver charge to the battery.

Can you charge a 9V device 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 do you charge a 9V rechargeable battery?

How to Charge your 9V Battery:

1. Insert batteries correctly. Make sure that the “+” and “-” terminals are aligned properly.
2. Put the charger into the correct household AC electronic outlet, the red led will light up for proper charging.

How do you charge a 12-volt battery without a charger?

3 Best Solutions For Charging A Power Wheels Battery Without The Charger

1. Method 1 – Use a car battery trickle car battery charger.
2. Method 2 – Use a 12v power supply.
3. Method 3 – Use a mobile phone charger with a DC to DC step up module.
4. Recharge battery at an Auto repair shop/ Authorized service center.

What voltage is too low for a 12-volt battery?

The lifespan of your battery will be moderately affected if it remains within this voltage range for extended periods of time. 12.0 volts or below – At 12.0 volts your battery is considered to be fully discharged or ‘flat’ and should be recharged as soon as possible.

Should I charge my battery at 2 or 10 amps?

It is best to slow charge the battery. Slow charging rates vary depending on the battery’s type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.

Can I use a 10v adapter for a 12V device?

No it’s not safe for the most of cases. There are two reasons. Since newer adapter has more terminal voltage therefore device is liable to draw more current and bad thing is that newer adapter is ready to provide more current.

What uses 9V power supply?

A lot of things use those small 9V batteries. Smoke detectors, some transistor radios (not so much any more), lots of handheld test equipment, electronic toys, etc. More and more things that in the past typically used 9V batteries are being designed to run from one to four AA or AAA cells.

Can you use a 12V adapter for a 5V device?

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc. Mostly it will get damaged.

How do I reduce 9v to 5V?

A 9v to 5v voltage regulator can be implemented with an LM7805 step-down voltage converter. It is used for (10mA to 1 Amp and more) medium to the high current application. The unique about this circuit is its ability to provide the same output current as applied at the input end.

How do you drop voltage?

The simplest way to reduce voltage drop is to increase the diameter of the conductor between the source and the load, which lowers the overall resistance. In power distribution systems, a given amount of power can be transmitted with less voltage drop if a higher voltage is used.

How do you reduce voltage from 12V to 6v?

It’s possible to step 12 volts down to 6 volts by incorporating a pair of 10,000-ohm resistors into the circuit. Cut two lengths of wire, and strip each wire of 1/2 inch of insulation at each end. Attach one end of the first wire to the positive terminal on the power supply.
