What ac voltage voltage to charge a 4.8v dc chargeable battery …
for 4.8V battery the 12 and 14V sounds too high (plugging a battery into possibly faulty charger is not a good idea) this is the trigger of the following GBP 85.00 = …
Before you begin charging an 8-volt battery, you need to prepare the battery pack and the charging equipment. Safety Precautions. Safety should always be your top priority when working with batteries. ... Yes, a standard charger can be used to charge 8 volt golf cart batteries. However, a resistor must be used to reduce the current …
With that in mind, then the charge current spec of 200ma, at a per battery rated voltage of 1.2v * 1.15 (Battery voltage plus 15%) would be 1.4 volts per battery (Cell), two in series would be 2.8v, 12 in series would be (1.4v * 12 batteries) at a charge voltage of 16.8 volts across the series battery bank of 12 batteries.
Is it okay to use a power supply that provides slightly more …
$begingroup$ @AO practically every adapter is designed to run off mains (house power), and the nature of "switching power supplies" makes it easy for them to support a wide range of input voltages with little impact on performance. The damage is likely not immediate, the 18V is fed to the charge controller for the laptop motherboard, typically these will have …

I am designing a product that has a 7.4 V, 5000 mAh battery (Two li-ion cells connected in series). Is it advisable to charge it with a 5V, 2 A charger? If no then what are the issues
So you can charge your 3.7V battery pack with the 5V charger, but be careful, choose one with the automatic circuit, just like the EasyAcc Power Bank. It is equipped with multi-protection, just like over …
It works fine, but I noticed that the new battery is rated at 14.8v, whereas the charger is rated at 19.5v. I don''t know what voltage the original battery was. I asked a friend who told me that usually the voltage of charger and battery should be the same, but that some laptops can have a higher voltage charger and only send the correct voltage …
Can I charge a 4.2 V battery with a 5 V adapter? [closed]
This is usually the same value in mA as the battery capacity in mAh. ie 1000 mA for a 1000 mAh battery 3300 mA for a 3300 mAh battery etc. When charging, EITHER stop charging when battery potential reaches 4.2V OR if you are able to hold the battery AT 4.2V, then stop charging when Ichg falls (under battery control) to say Ichgmax/4.
