Can you charge 1.2 V battery with a 5V charger?
Theoretically,you can. But, since the voltage difference between the charger’s output and the battery is large, the current flowing into the battery may be larger than the charger’s limit of 450ma. That can lead to failure of the charger.
Can I charge a 1.5 volt battery with a 5 volt charger?
Yes. The volts has to be correct, the amps just has to be high enough. The device that you are charging will only take as many amps as it needs.
How long does it take to charge a 1200mAh battery?
Answer: If your battery is 3S 11.1V 1200mAh , It can take 1 or 2 hours to charge full, if your battery is over 12000mAh 3S Lipo battery, It may take over 10 hours to charge full.
Can I use a 5V 3a charger with a 5V 1.5 a device?
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 I use 1.2 V batteries instead of 1.5 V?
Q : Can I use 1.2 V rechargeable batteries in devices that usually take 1.5 V throw away batteries? Yes, most definitely. Using 1.2 V rechargeable batteries will have no effect on the use of the equipment. In fact an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge.
What does LR mean on a battery?
round alkaline battery
For example, LR means round alkaline battery, while CR means round lithium battery. The first letter denotes the type of battery, while the second denotes the shape (R meaning round).
Can battery charger be used as power supply?
A battery charger is a type of power supply. As long as you had enough voltage, enough amperage, (and enough water) and rectified AC you could charge the battery.
How long does a 1200 mAh battery last?
If it is a smartphone, it will normally take 6–7 hours (normal), 2–3 hours ( rough usages means using internet,listening to music etc.)
