SELECT CHARGING RATE
This smart charger has an optimal function (defaulted setting). If
you don't want to use the best settings, you can select your
expected battery type, charging rate, and other modes
manually. The smart charger has three additional charging rate
options. Press the "AMPS" button to choose the desired
charging rate.
2A- Can be used for little-capacity battery or slow charging.
10A - Can be used for medium-capacity automobile battery or
quick charging.
25A - Can be used for large-capacity or rapid charging.
Note: If you want your battery to sustain a longer life, slowly
charge it. Slow charging will take longer time but will charge
your battery more thoroughly. If your battery needs to charge in
a short amount of time, use the rapid charge setting.
BATTERY RECONDITIONING
When your battery has been unused for long periods of time,
the battery will be in a deep discharged state. The battery
reconditioning function is for recovering the battery from deep
discharge and help the battery last longer.
CHARGING TIME
Charging time may vary depending on some factors listed below
stop the process.
* Battery State
Depending on the voltage of your battery, it may take up to 10
hours to charge. Batteries with higher voltage can usually be
charged in a few hours.
* Battery Rating
A higher rated battery will take longer to charge than a lower
rated battery under the same conditions. A battery is rated in
ampere-hours (Ah), reserve capacity (RC) and cold-cranking
amps (CCA).
* Charge Rate
The charge rate is measured in amps. A battery charged at a
lower rate will take longer time than a battery charged at a higher
rate. However, smaller batteries can be easily damaged by
charging at a rate which is too high for the capacity of the battery.
* Temperature
Cold temperature will affect a battery's ability to accept a charge.
Charging in cold temperatures will increase the amount of time
required to charge a battery.
DESULFATION
If the battery is left discharged for an extended period, the battery
could become sulfated. A sulfated battery will not accept a
normal charge.

1. Desulphation: Pulse charges the battery to break down the
buildup of lead sulphate crystals. Lead sulphate crystals can occur
when a battery has been discharged or left unused for a period of
time, seriously affecting the performance and lifetime of the battery.
2. Soft Start: A slow steady buildup of the charging process that
limits the power supplied to protect the battery.
3. Constant Current:Will charge according to the set current full,
is the main part of the charging process.
4. Constant Voltage: The battery is fully charged by slowly
lowering the charging rate, allowing the battery to absorb more
energy.
5. Analysis: Automatically test the state of the battery after
charging if the battery is abnormal, it will enter the repair stage, if
the battery is normal, it will enter the floating charging stage.
6. Recondition: Unique charge state to recover deeply
discharged batteries.After repair, return to the constant current
stage to continue charging. If repair fails, an error will be reported.
7. Float: Trickle charge and nearly get your battery 100% fully
charged during this stage.
