BAC06A Switch-type Battery Charger Version 1.5 2020-03-13 Page 4 of 7
1 OVERVIEW
BAC06A switching battery charger adopts the latest switch power components, which is designed for
charging lead-acid starting battery according to its property. The charger is suitable for lead-acid battery
float charge. The maximum charge current for 12V charger is 6A; the maximum charge current for 24V
charger is 3A.
2 PERFORMANCE AND CHARACTERISTICS
Characteristics are as below:
—
Designed in switching power structure, wide range of AC voltage input, small volume, light weight and
high efficiency;
—
Two-stage charging method (constant current firstly and then constant voltage), fully considering
charging property of the lead-acid battery, can avoid overcharging and extend the battery life to the
fullest;
—
With short circuit and reverse connection protection;
—
Charging voltage and current can be adjusted via potentiometer on site;
—
LED display: Power indication and charging indication;
—
Horizontal type for installation of BAV06A, easy to install;
3 CHARGING PRINCIPLE
Chart 1. Charge Principle
According to charging property of the lead-acid battery, battery charger uses 2-stage charging
method and charge mode is “constant-current”. When battery voltage is under the threshold, it is
charging in constant-current mode; when the battery voltage is higher than the threshold
，
the charging
current is decreasing as the battery voltage is rising until it reaches the set voltage, and then charge
mode is turned into “floating charge”. Charge current is gradually reducing and battery voltage is rising
up to the set value. When charging current is lower than 0.3A, the battery is basically fully charged
(charging indicator eliminates). Afterwards, charging current will offset self-discharge of the battery and
long time charging does no harm to the battery. Thus the charger can not only maintain a full charged
condition and but also ensure the battery life
.
