DZM Series is a VRLA battery series using poor-fluid design and tight assembly technique. The series uses a special craft formula for low-temperature and high-current discharge performance, high-purity raw materials and chemical additives to reduce self-discharge, and an electrolyte formula that supports recovery after deep discharge.
Product Characteristics
Poor-fluid design and tight assembly technique.
Low-temperature and high-current discharge performance.
Low self-discharge rate, lower than 3% per month during storage or non-use.
Good restoration characteristics after deep discharge.
Charging
Constant-current charging: charge to 14.8V/pc by 0.15C2-0.18C2 A constant current.
Constant-voltage charging: continue charging at constant voltage 14.8V/pc, then transfer to trickle charge when charging current drops to 300mA for 10Ah or 500mA for 17Ah.
Trickle charging: continue at 13.8V/pc until charging current is minimal, stable and unchanged for 2 hours.
Discharging
Maximum starting current should be limited to 1.5C.
Normal operating current should be controlled within 0.2C.
Minimum discharge protection voltage for each 12V battery is 10.5V.
Recharge promptly after use, especially after about 65% depth of discharge.
