LCD Display Information:
Charging Features:
Bad Battery Dete tion (1)
▪Measures the voltage of your battery prior to chargi g.
▪If the refere ce voltage is ≥30V±0.5, it's co sidered a 'bad
battery'.
Devul anisation (2)
▪Whe the chargi g period reaches four hours i Pulse
Chargi g mode a d the battery voltage variatio exceeds the
voltage setti g, the system e ters the ext mode.
▪Whe the battery voltage variatio is less tha 2V (12V
battery) or 4V (24V battery), devulca isatio is o lo ger
performed a d the system e ters the ext mode.

Pre Charge (3)
▪Ide tifies the battery voltage before chargi g.
▪If the battery voltage is lower tha the refere ce voltage, the
battery will be pre-charged i order to avoid damage to the
battery.
▪12V: 5-8V 2 mi utes, 8-10V 9 hours.
▪24V: 5-16V 2 mi utes, 16-20V 9 hours.
Constant Current (4)
▪The mai chargi g phase.
▪The battery will be charged with the maximum curre t as
quickly as possible.
▪70%~85% of the battery is charged i this stage.
Constant Voltage (5)
▪The boosti g phase.
▪The charger co sta tly adjusts the charge so as the battery
voltage gets higher, the chargi g curre t becomes smaller.
▪Co sta t voltage chargi g e ds whe the chargi g curre t
drops to =< 0.5C, at which time the battery should be almost
fully charged.
Re ondition (6)
▪Whe the battery has reached maximum voltage, the charge
cha ges to reco ditio mode si ce some batteries ca be
charged to 15.7V.
▪This charge lasts 2±0.2 hours at most a d is o ly activated by
selecti g 12V/RECON.
Voltage Analysis (7)
▪The i ter al circuit automatically detects the variatio of
battery voltage.
▪A alarm will sou d whe the voltage exceeds 2V (12V) or 4V
(24V).

Float Charge (8)
▪The mai te a ce charge.
▪Trickles the charge u til the battery is early at 100%
capacity.
▪Chargi g with a small curre t ca elimi ate the vulca izatio
of the egative electrode plate.
Pulse Charge (9)
▪O ce the battery voltage has bee adjusted i the previous
mode, the battery voltage retur s to 13V/26V whe the pulse
chargi g mode is executed.

Error Codes Solutions
Check the battery voltage is for 12V
system
Battery has problem. Replace with a new
battery and try again.
Battery is too old or damaged. Replace
with new battery and try again.
Check the battery voltage is for 12V system
Remove the reverse, unplug immediately
from mains, connect the red clamp to
positive (+) battery post, and black
clamp to negative (-) post.
Check battery specification,12V battery
use 12V mode; 24V battery use 24V mode.
If still doesn't work,replace with new
battery and try again.
