Types of battery charging methods

Types of Battery Charging Method

The correct device and charging techniques will prolong the lifetime of your battery.
They can stop the harm which will occur from undercharging or overcharging the device.

There are five basic recharging methods.

They are constant voltage, constant current, pulsed current, tapered current, and trickle charging.

Certain batteries need a selected recharging method whereas different batteries will use completely different strategies.

Constant Voltage

This type of charger maintains a continuing voltage no matter the battery’s charging standing.
It is the foremost basic technique of charging batteries.

They are widely available in the form of inexpensive car battery chargers.
It uses an instantaneous current from an influence provide.

Constant-voltage chargers square measure used often to charge batteries that need extended charging periods, like lead acid automotive batteries.

These chargers are not generally recommended for devices that require frequent cycling.
This technique is acceptable for lithium-ion batteries if the charger is provided with electronic equipment that protects the battery.

Constant Current

These chargers maintain a continuing flow of current to the battery, but the voltage may vary.
They are usually equipped with automatic shutoffs that activate when the battery reaches a full charge. This method is often used for nickel-cadmium and nickel-metal hydride batteries.
Pulsed Current
As the name implies, this sort of charger provides current to the battery in pulses.

The length of the pulses and the intermittent rest period can be set to various lengths, which ensures a more controlled charging process.

This recharging technique reduces the chance of conductor harm as a result of the chemical within the battery stabilizes between pulses.

This technique may be employed in conjunction with burp or negative pulse charging.
It shortens the time needed to charge battery by depolarizing the battery cells and cathartic any repressed gases.

Taper Current

These chargers are available in unregulated and regulated models.
An unregulated charger will overcharge and harm battery.

These chargers are usually limited to sealed lead acid batteries.
A regulated taper charger maintains the voltage at a secure, constant level.

Trickle Charge

This technique compensates for the self-discharge rate that happens once battery isn't in use.
It provides a continuous, long-term charge.

This technique is unsuitable for Li and nickel-metal binary compound batteries as a result of they're at risk of overcharging.

After the battery is absolutely charged, the charger automatically switches to a trickle charge.
This is a typical charging technique for quality scooters, RVs, and boats.
After the battery is absolutely charged, the trickle charge maintains the maximum power level so that the battery is always ready for use.


Some smart chargers enable you to connect the charger and battery indefinitely without damaging the battery.
