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.
Can you charge an 8 volt battery with a 12 volt charger?
Yes, you can use a 12-volt charger to charge an 8-volt battery. Usually, the 12-volt charger will come with more output power than the 8v battery itself.
Can you charge a 9V battery with a 6V 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 you charge a battery with a different voltage?
Voltage is the power pushed by the power supply. The voltage output is critical and must match your new charger. For example if you are using a charger with 20V output, look for a replacement device with matching voltage. By using different voltages, you risk shortening the lifespan of your batteries and your device.
How do you charge a 9V rechargeable battery?
How to Charge your 9V Battery:
- Insert batteries correctly. Make sure that the “+” and “-” terminals are aligned properly.
- Put the charger into the correct household AC electronic outlet, the red led will light up for proper charging.
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 you charge a 48v battery with a 12v charger?
However you can charge 48v with a 12v charger it will just take a lot longer also the slower you charge your battery the more life you will get out of it charging at a high rate does damage battery faster less life on battery.
Can I charge a 5V battery with a 9V charger?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
Can you charge a 9.6V battery with a 12V charger?
The answer is no, not directly. If the 12V battery is completely discharged, a 9.6 V battery connected in parallel to it, will put some charge into the 12V battery but no where near enough for the 12V battery to be fully charged.
Can I use a 6V power supply on a 9V?
Yes you can! the thing is you need voltage regulator which converts 6V ,1.5 A to 9V , 0.6A, however this will drain battery faster it has many other reasons.
What happens if you charge a battery with higher voltage?
As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.
What happens if you charge a battery with the wrong voltage?
In all cases with lithium batteries: If the charge voltage is lower than the nominal pack voltage you’ll not charge the battery; if it higher you’ll have a fire or be lucky and just ruin the cells.
What happens if you use a higher voltage battery?
A higher voltage battery has the potential to “push” more current–that is, more electrons–for a given resistance. This translates to the capacity for greater work, which is the same thing as more power. Higher voltage also means less current to do the same amount of work, so longer battery life.
What is 9V charging?
The 9V/1.67A is fast charging. So when you plug in a device with Fast charging enabled such as a S7 edge it charges at this rating. When you plug in a device without fast charging or fast charging disabled, it will charge at the 5V/2A rating.
Can regular 9 volt batteries be recharged?
You don’t need to buy a regular 9v battery because these Li-Ion cells can be recharged 1000 times. The capacity of the device is the same as that of a simple 9v battery. The 9volt output is not going to be shorted.
Can I charge a golf cart with a 12 volt battery charger?
Your best and safest bet is always the golf cart battery charger, but if your batteries are completely dead or you only have an automotive 12v charger on hand, you’re in luck (sort of).
Can you charge a 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 12 volt batteries in series?
Charging time will be the same as charging a single battery. Charge more than five batteries by connecting one 12-volt battery charger across each battery in the series, as if each battery were the only one being charged. Charge all the batteries at the same time.
Can I charge a 48 volt battery with a 24 volt charger?
You really can’t. It’s called a 48v battery charger because it’s designed to charge 48v batteries. Note: other posters have posited charging two 24v batteries in series. This would be (relatively) safe – and work – if, and only if, the batteries are near identical in type, size, capacity and existing charge.
Can you charge a 60v battery with a 48v charger?
yes. but only if you make sure that the charge current is not more than 1/10th of the Ah capacity.
Can I use a 5V plug on a 9V device?
No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn.
