Amperage is the measure of electrical current, and it is critical to understand when charging a battery. A higher amperage will result in a cooler, steady power supply and shorter charge time, while a lower amperage can …
If you have a choice in the matter, stick with chargers that have the same amperage as the battery. But the charger will still work even if the amperage is higher so long as the voltage is the same. Look at the voltage on the adapter and compare it to the information on the battery.
As mentioned, however, trying to draw more current then the charger is capable of may cause heating problems. The current rating on the charger indicates the maximum current it can supply. So it is OK to use a charger that can supply more current, but not the other way around.
Higher amperage means faster charging. More current flows through the device, delivering more electric charge per second. Most devices come with a recommended maximum amperage. Using a higher amperage charger charges the device faster without causing damage IF the voltage is correct. So, that’s great and all, but what does it all mean?
Amperage is the measure of electrical current, and it is critical to understand when charging a battery. A higher amperage will result in a cooler, steady power supply and shorter charge time, while a lower amperage can cause the charger to overheat.
Contrary to what some comments/answers may suggest, the charger needs to be told the maximum current to deliver. They normally don't/can't 'sense' it. The important thing is to use the correct battery charger circuitry based on the chemistry of the battery.
If you use a high amperage charger on a device that requires low amps, it will not damage your device. As long as the correct voltage is used, a device will draw only the amperage it needs. The only way it can damage the battery is if an incorrect voltage is used, i.e., a higher voltage than the device is rated to accept.

Get PriceWhen the battery is connected and tries to draw more than the set current, the charger will drop its voltage to limit current. At the same time the battery voltage will rise due to the charging current. When battery voltage reaches 8.4V the charger will progressively lower the charging current to prevent the voltage from going higher than 8.4V.

Get PriceA battery charger limits current going into the battery, and its current rating will be matched to the battery it was designed to charge. Depending on the battery chemistry, voltage may also be limited, eg. Lithium Polymer is 4.2V/cell. However the label usually shows the nominal voltage, eg. 3.7V for a 1 cell Lipo, 7.2V for a 6 cell Nicad.
Get PriceCan I charge a 12V battery with a higher current? While you technically can, it''s not recommended. Charging a battery with a current higher than its recommended rate can lead to overheating and potential damage. Always refer to the manufacturer''s guidelines. Is Charging a Car Battery Via the 12V Socket Safe and Effective?
Get PriceWhat Happens When You Use A Charger With A Higher Amperage? Your home supplies AC power, which a charger converts into DC power for your device. AC (Alternating Current) power is called so because the current changes direction. DC (Direct Current) power differs because it always moves in one direction.
Get PriceThe basic algorithm for Li-Poly batteries is to charge at constant current (0.5 C to 1C) until the battery reaches 4.2 Vpc (volts per cell), and hold the voltage at 4.2 volts until the charge current has dropped to 10% of the initial charge rate. In addition, a charge timer should be included for safety.
Get PriceFor a 1300 mAh battery, C = 1300 mA. The charging current is typically set externally to the charger chip using a couple of resistors. Values of 0.5C (650 mA in this case), 0.8C and 1C are common. A rate of 2C (2600 mA or 2.6A) would be classified as a fast charge.
