BAC06H Battery Charger Version 1.1 2017-06-21 Page 4 of 6
1 OVERVIEW
BAC06H 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. BAC06H is a kind of high voltage charger and its input voltage can be reached at 480V. The
maximum charge current for 12V charger is 6A; the maximum charge current for 24V charger is 3A.
2 PERFORMANCE AND CHARACTERISTICS
1) Designed in switching power structure, wide range of AC voltage input, small volume, light weight
and high efficiency;
2) Two-stage charging method (constant current firstly and then constant voltage), fully considering
charging property of the lead-acid battery, can avoid overcharging and extremely prolong battery life.
3) With short circuit and reverse connection protection;
4) Floating voltage can be adjusted via potentiometer on the spot;
5) Suit for 12V and 24V battery with the corresponding BAC06H-12V charger and BAC06H-24V
charger;
6) LED display: Full charged indication and charging indication;
3 CHARGING PRINCIPLE
According to charging property of the lead-acid battery, BAC06H 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 is off). Afterwards, charging current will offset self-discharge of the battery. Thus the
charger can maintain a full charged condition and extend the battery life.
