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.
