AA battery charger

Additional resources

When we drill down the specification of the battery chargers, they come with a lot of requirement and specification, sometimes it sounds too technical to a certain people.

Generally the current and voltage of AA battery charger depends on

- technology

- voltage capacity

- security capabilities

- manufacturer

When a battery being recharged, it is a process where the battery charger sends in a current through a rechargeable battery. It is rather interesting to find out what are the battery charger available in the market and their functionality and working technology.

• Simple charger

This is the first level entry for a simple charger to charge a rechargeable battery in a simple way. The charger transmits a constant voltage of DC-power through a battery cell. It will not change the amount of energy omitted in relation to time, temperature or maximum energy capacity. This type of charger is quite common and normally selling at low price due to it takes long time to recharge a battery to a full charge.

• Trickle or float battery charger

These are simple battery chargers but charge the batteries slowly at the battery’s self-discharge rate. As compare with other types of charger, This tickle or float battery charger is the slowest chargers among them. The only advantage for this kind of charger is you will never worry about overcharging the battery due to the period of time required to fully charge the battery is slower than the self-discharge rate. The battery can be left in the charger over night.

• Intelligent battery charger

As the name implies, the intelligent battery charger will provide a user-friendly feature to its user to monitor the charging level of the battery before the cells are treated. It will also measure the temperature and calculate the amount of time required to fully heal the batteries cells. An intelligent charger has a built-in auto alert system which reduce the charging speed when the battery gets 85% of the maximum charge and complete the full charge with the trickle system. Some even has a buzz when the charging process is completed and automatically cut off the current that sent to the battery.

• Fast charger

A fast charger applies a control circuitry in the battery to quick charge the battery. The cell being quick charged normally will develop heat. To counter off the heat generated by the quick charge issue, a fan will come with the fast charger to keep the cells from being “burn”. However a fast charger may spoilt the rechargeable battery in the long run.

• Pulse charger

The pulse technology used in this type of charge to recuperate the batteries. In this way, the pulse charger can be used to charge several types of batteries compatible with any size, voltage, capacity or chemistry compound of the batteries. Pulse charger can also be known as the Universal charger which can charge the automotive and valve-regulated batteries. Using the similar approach like the intelligent charger, the pulse charger sends a pulse to check the current state of the battery, then quick charge the battery up to 85% before switching to trickle system to complete the charging process.

• Electromagnetic induction charger

An inductive charger uses electromagnetic induction to revamp a battery. They use a pair of inductive couplers to send the electromagnetic energy to an electric device in the charger station. It is very popular used in the bathroom utility due to the charger does not run into the risk of electrocution.

All of the above charges are easy to find and practical. You have to decide the type of battery used before choosing the suitable charger.
