Charging Curve for Lead-Acid Battery Charger

Charging Curve for Micro Battery Charger (Dry Battery)

Charging Curve for Micro Battery Charger (Wet Battery)

1.Max. Boost charge time ≧ 12 Hrs, jump to section D.

2.Charge current ≦ 0A, relay open, then jump to section D.

3.Max. Float charge time ≧ 40 min. Then relay open.

4.If battery voltage drop 2.1V per cell, then recharge.

5.If deep discharge over 30 min., then relay open and red LED ON.

6.Section A, B, C P.W.M control.

If charge current become 0 in any section, jump to section E.

Remark:
Red LED indicator
*1 No battery --> Red flash (2Hz)
*2 OTP/OVP --> Red ON
