The simple charger will not alter any of the output based on the charge on the battery or based on the charging time. If you are looking for an affordable charger for your rechargeable AA and AAA batteries, then this charger is the one for you.

There are also pulse chargers where there is a series of current or voltage pulses to feed the battery. The pulses of DC will strictly control the amplitude, repetition rate, pulse, pulse width, and the rise time. One of the best things about pulse chargers is that they have the power to work with any size of capacity, voltage or the batteries’ chemistry. Also, you shouldn’t worry about overheating the battery because there is a high instantaneous voltage applied.
There are chargers which use pulses to check the battery’s current state while the charger is connected. A constant charging will be used for fast charging chargers.
Smart chargers or intelligent chargers contain chip or electronic device which can communicate about the condition and the characteristics of the battery. If you are using a smart battery, then this means that you will also need a smart charger. This kind of charger will work depending on the battery’s condition and also has the ability to modify the charging if required.
Also, the output current of the smart charger will depend on the state of the battery. The intelligent charger has the power to monitor the temperature and voltage of the battery to help terminate the charging or for maximum charge.
How Does The Charger Determine The Battery’s Status
Typically, the charger can determine the status of the battery using a light that is attached to the charger itself. The components of the charger will send a signal to the device for the user to know if the battery is already fully charged. Typically, the light will consist of different colors to help you understand as to what status your battery is currently in. Green means that it has higher energy and can already be used, while red means that it still needs to be recharged.
