Product Description:


Smartcharger is Maili's following generation smart charger. It has many of the protective features that consumers expect to have in a charger, including battery misconnection(wrong voltage), reverse polarity, battery disconnection or not connected, and battery failure analysis. 

The latest high efficiency switching topology and microcontroller power management are utilized in its design. 8 charging stages are offered in our products. Charging rate/type selection can be easily made by the user through the selection switch on the front panel.

Depending on battery brand and type (lead acid, gel, lithium iron, and lithium manganese), the battery may require special charging curves and adjustment to the protective functions which differs from the standard settings. The charging curves and protective functions can be customized by reprogramming its firmware. Please note: the factory charging curve is for charging lead-acid battery. Please contact with Maili regarding other types of battery charging requirements.

Multiple Charging Stages:  8  stages, extending the service life of battery 


1. Stage 1(pulse charging) :


Pulse charging is used to revive tired lead acid battery which is either improperly charged/discharged or allowed to self-discharge as occurs during non-use. Basically,

help to restore its normal chemical properties.


2. Stage 2 (soft start):


Use low charge voltage and current to preparethe battery toaccept upcomingbulk charging,

so a better charge can be applied.


3. Stage 3 (constant current):


A high constant current is provided so the battery can be quickly charged to 2.4Vper cell.


4. Stage 4 (constant voltage):


A constant voltage of 2.4V per cell is provided until the charging current naturallytapers down

to a low level.


5. Stage 5 (analysis):


The charger will stop charging for 2 minutes to determinebattery status. If thebattery voltage

is higher than 2.1 V per cell, the battery is determined as OK andwill move on to stage 6.

If the battery voltage is lower than 2.1V per cell, the batteryfail indication will come ON,

and the charger will berecharged following the before steps second time.


6. Stage 6 (recondition boost charge):


Boost voltage is provided to recondition the battery storage capacity to its originalstate.


7. Stage 7 (float charge):


A float voltage of 2.3V per cell is provided for extended period of time so that thebattery can

maintain full charge.


8.Stage 8 (maintain):


Maintenance charge is provided to compensate for battery self- discharge and extend battery life.
