Advanced Settings – Charge Timeout
Chg Timeout – limits the amount of time for a pack to charge. This is an important safety feature.
Fast charging presets with high currents should have short charge timeout settings.
Chg Cap Limit – limits the capacity going into the pack during a charge. This complements the
Chg Timeout as an important safety feature. Fast charging presets with high currents should
have low Chg Cap Limit settings.
Advanced Settings – Discharge Timeout
Disch Timeout – limits the amount of time for a pack discharge. If this timeout is reached, the
discharge will stop.
Disch Cap Limit – limits the capacity going out of the pack during a discharge.
Advanced Settings – Trickle Settings
Mode – sets whether to trickle charge after a charge. Also allows GT1000 to skip directly to
trickle charge. This is only needed for NiCd/NiMH batteries when a fast charge isn’t desired.
Trickle Charge only can be helpful to increase the life of those batteries.
Trickle Amps – sets the current for the trickle charge mode. Typically, trickle current is set to
1/20 of the capacity of the battery.
Trickle Timeout – sets the time limit for a trickle charge. The ideal time is 24 hours. For
NiCd/NiMH, this timeout allows the cells to balance to full charge. The weaker cells will
overcharge at a slow enough rate that they are not damaged and the stronger cells will catch up
and fully charge.
Advanced Settings – Float Settings
Mode – sets whether to trickle/float charge after a charge.
Float Amps – sets the finishing current for Lead Acid batteries. Finishing is very important for
Lead Acid batteries because slightly overcharging the battery removes the sulfides that build up
on the plates from a deep discharge.
Float Timeout – sets how long to finish the cells by a slight overcharge for Lead Acid batteries.
Advanced Settings – Cold Weather Settings
Cold Wea T – sets the temperature where the GT1000 reduces the charge voltage set point.
The temperature is measured inside the charger.
Cold Wea V – sets how much to reduce the charge voltage set point in cold weather. Lithium
charging in cold conditions need to have a reduced charge voltage. However, if the charge
voltage set point is less than 4.200V, cold weather can be disabled.
Advanced Settings – Unbalanced Charge
Charge Amps – sets the charge current. The charge current is used for the constant current
portion of the charge.
Chg V/cell – sets the desired cell voltage for Lithium packs. This value can be reduced to under
charge a pack, or raised to over charge a pack.
No of Cells – GT1000 only allows 2s Unbalanced Charging. For 1s cells, use Basic Charge.
Advanced Settings – Unbalanced Discharge
Discharge Amps – sets the discharge current (or regenerative discharge current if the Regen
Discharge option is On).
Disch V/cell – sets when to stop the discharge.
