Can I charge a 3.7 V battery with 5V charger
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.
What voltage should I charge my 3.7 V battery
It is best to use 4.2V constant voltage charging mode, you don't need to pay attention to the charging time. Charging with 5V is prone to danger of overcharging.
Can you charge a 3.7 V battery with a 6V charger
If you use a 6 volt charger, the input current will be higher than designed. This may damage the charge control circuit. You are taking a chance.
Can I use 5V adapter in 3.6 V
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 we charge 3.7 V battery with a 4.8 V charger
Lithium ion are often quoted as 3.6 or 3.7v “nominal” or average. Either way, the 4.8v charger is unsuitable. It might overheat, or eventually overcharge the battery, which will cause it to overheat, and possibly worse.
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.
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.
What happens if you charge a 6V battery with a 5V charger
Secondly, a lower voltage charger will never be able to produce enough power to fully charge your 6V battery. It might charge your battery enough for you to get your device jump started, but that's about it.
Can you charge a 3V battery with a 5V charger
Probably not directly. A 5V charger has a specified voltage. If 5V are applied to a discharged Lithium-Polymer battery (around 3V), the current going into the battery might be several times over the maxium tolerable charging current for a 380mAh battery, which would be 380mA (better is 100mA).
Can I use 5V for 3.7 V
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.
Can I use 5V for 3v
It could result in immediate failure that could result in smoke or even fire.
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.
Is it bad to charge a 6V battery with a 12V charger
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 I charge 18650 with 5V
It can support up to 2.1A charging current under 5V input power, and 0- 3.5A output at 5V. The battery full charging voltage is 4.2V.
Can I use a 5V adapter to power a 3.7 V device
In order for current to flow there needs to be a useful voltage difference. There is a voltage difference between 5 and 4.2 and 3.7. If you charged with 3.7 there would be no voltage difference, no current and no charging. Less than 4.2 volts and it won't charge fully.
How do you charge a 3.7 V battery
