Some of the best battery charging techniques are available for many different types of batteries. With the proper power supply and the correct charger for your battery type, you will be able to prolong the charge life of your batteries. This will also help to lengthen the number of times you can recharge them. Four of the most popular charging methods are constant voltage, constant current, taper current, and a pulsed charge. Here are a few facts on each of these four as well as the most popular batteries to charge with each method. The batteries listed are not all-inclusive, so be sure to check with the batteries manufacturer for the charging options on the ones you have purchased.
1. Constant Voltage
A constant voltage charge provides a high initial charge to the battery then it slowly decreases until the voltage level is read again, at which point the battery charge will again be raised and slowly lowered again. The constant charging of the battery with this method will cease once the full voltage of the battery is reached.
2. Constant Current
Using a constant current charger is one of the more effective ways to charge many different types of batteries. The most common types that are best charged with a constant current include lithium-ion, nickel-metal-hydride, and nickel-cadmium. Not all types of these batteries require a constant charge. Many different constant current chargers also are available for lithium cell batteries. These types of batteries require a certain voltage and a constant voltage charging requirement.
3. Taper Current
There are regulated and unregulated taper chargers available. A better choice for charging such batteries as a sealed lead-acid battery is the regulated taper charger. These regulated taper chargers do not allow the voltage to reach more than a trickle charge. This, in turn, will allow the charger to be used to maintain the battery as well as charge the battery.
4. Pulsed Charge
A pulse charge is said to be used to provide any type of battery with an additional charge. This includes lead-acid batteries as well as even car batteries. A DC charge is used to provide constant pulses of energy to the cells of the battery until it is fully charged. A pulse charger can also be used as a sort of trickle charger in order to maintain a charge once full capacity is met.
There is much more to charging a battery than just plugging it in. You need to know if the battery is compatible with the charger, as well as if you need to take the batteries off the charger to avoid a loss of charge. Most charges will trickle. Charge the batteries to keep them at a full charge and high operation level. It is recommended for some to remove them after a full charge has been reached. Whether you have decided that constant voltage, constant current, taper current, or a pulsed charge is best for your rechargeable batteries you will benefit from the information learned about the different types of charging methods available.
