Can I charge 3.7 V battery with 4.5 V charger
Generally, a 3.7v lithium battery needs a "protection board" for over-charging&discharging. The battery without a protection board can only be charged with 4.2V voltage, because the ideal full charge voltage of a lithium battery is 4.2v, once the voltage exceeds 4.2v, the battery may be damaged.
Can a 4.2 V charger charge a 3.7 V battery
The charge cut-off voltage of a 3.7V battery is exactly 4.2 V. Therefore, it is possible to use a 4.2V charger as a 3.7V battery charger, but using a 5V charger to charge a 3.7V battery will cause the battery to overcharge.
What voltage to charge 3.7 V
4.2V
Use a 4.2V charger to charge your 3.7V lithium ion battery that does not have a protection circuit board. The maximum safe voltage a 3.7V Li-ion battery can hold is 4.2V.
What happens if you charge a 3.7 V battery with 5V
You can't just connect 5v to a lithium-ion battery and expect it to work. What will happen is the cell will reach 4.2v or fully charged, then continue to rise, much past 4.3v it will start to heat up as it cannot accept any more charge. If you carry on the cell will vent, and might even catch on fire.
Can you charge a 3.7 V battery with a 5V phone charger
Short answer: No, because your "5V USB Charger" is not a charger – it's a power supply. No, you can not. You must read this: Safety Concerns with Li-ion. (There is a reason why R/C enthusiasts put Li batteries into flameproof bags, when they charge them.)
Can I charge a 3.6 V battery with a 5V charger
A 5v charger for a 3.6v device is very likely, maybe even guaranteed to damage your device in a serious way. You should use the charger that came with it or find an identical one.
Can I charge 18650 to 4.2 V
18650 lithium-ion batteries are charged up to 4.2V and down to between 2V and 3V depending on the cell's specification for cut-off voltage. To be safe, never discharge lower than 3.0V unless you know your cell's specification.
Can 5V charge 3.7 V
Charging a 3.7v battery with a 5v charger. Here's everything about using a 5 V charger to charge a 3.7 V cell phone battery being safe to use: It's not safe to charge a 3.7 V cell phone battery with a 5 V charger for both the equipment and personal safety.
Can I charge 3.7 V battery with 12v charger
Originally Answered: Can I charge 3.7volt lithium ion four battery in series with 12 volt charger No, You can't do it by 12v supply but you can do it if you add some proper regulation and auto-cutoff circuit in between the 12v supply and the battery.
How do I charge a 3.7 V battery
For safe charging of a 3.7 V Lithium-ion batteries they should be charged at constant-current of 0.2 to 0.7 times their capacity, till their terminal voltage reach 4.2 V, later they should be charged in constant-voltage mode till charging current drops to 10% of initial charging rate.

What is the difference between 4.2 and 3.7 18650 battery
The 18650 cell has voltage of 3.7v and has between 1800mAh and 3500mAh (mili-amp-hours). 18650s may have a voltage range between 2.5 volts and 4.2 volts, or a charging voltage of 4.2 volts, but the nominal voltage of a standard 18650 is 3.7 volts.
Can we charge 3V battery with 5V charger
Don't do this. Depending on the 3V supply, too much current might damage the battery. Why do some phones need a 5V charger although the battery needs 3.7V only Not just some phones but virtually all phones using a one cell lithium ion battery of nominal 3.7 volts.
