THREE STAGE CHARGE CYCLE:
An Electronic Control Module (ECM) controls both the output voltage and current of the charger through three
separate charge states:
1. A high current, fast charge state: Battery charges at 3,500mA fast charge current rate until battery
voltage reaches peak voltage.
2. A topping charge state: Battery charges at peak constant voltage and current begins to fall until
current is less than 700mA.
3. A precision oat charge state:Thechargerchangestotheoatstateandholdsthebatteryvoltage
atcontinuousoatvoltage.Thisallowsthechargertoremainconnectedtothebatteriesduring
periods of non-use, keeping the batteries in a state of full charge.
4. Charger cut-off: To comply with mandate of DOE this charger automatically cuts off after 20 hours
of continuous operation, and CHARGE STATUS LED turns off. It is designed with auto restart to
keep batteries charged.
SAFETY FEATURES:
1. Short-circuit Protection – protects the charger from short-circuit damage.
2. Overcurrent Protection – protects the charger from overcurrent demand.
3. Overvoltage Protection – protects the batteries from damage.
4. Battery Polarity Reversal – protects the charger and batteries against incorrectly installed batteries.
5. Low Battery Voltage – when the battery ls under14V, the charger will not engage.
