Specification

Cells Per Unit 6 Voltage Per Unit 12 Capacity 160Ah@20hr-rate to 1.75V per cell @25℃ Weight Approx. 48.0 Kg (Tolerance±3.0%) Internal Resistance Approx. 6.0 mΩ Terminal F12(M8)/F5(M8) Max. Discharge Current 1600A (5 sec) DG (Deep Cycle GEL ) series is pure GEL Design Life 15 years (floating charge) battery with 15 years floating design life , Max. Charging Current 32.0 A it is ideal for standby or frequent cyclic C3 109.2AH discharge applications under extreme C5 123.0AH environments. By using strong grids, high Reference Capacity C10 141.0AH purity lead and patented GEL electrolyte, C20 160.0AH the DG series offers excellent recovery capability after deep discharge under Float Charging Voltage 13.6 V~13.8 V @ 25℃ Temperature Compensation: -3mV/℃/Cell frequent cyclic discharge use, and it can offers 2 times cyclic life than the standard 14.2 V~14.4 V @ 25℃ Cycle Use Voltage series. It is suitable for solar & wind Temperature Compensation: -4mV/℃/Cell system, marine, deep discharge UPS etc. Discharge: -40℃~60℃ Operating Temperature Range Charge: -20℃~50℃ Storage: -40℃~60℃

Normal Operating Temperature Range 25℃±5℃ RITAR Valve Regulated Lead Acid (VRLA) batteries can ISO 9001 ISO 14001 OHSAS 18001 be stored for up to 6 months at 25℃, and then recharging Self Discharge is recommended. Monthly Self-discharge ratio is less than 2% at 20℃.Please charged batteries before using.
