Specification

Environment
◆ Working Temp:-30℃ ～ 45℃,Normally use batteries with 10℃ ～ 30℃
With lower working temperature, battery actual capacity will be reduced;with higher working temperature,
battery lifetime will be greatly reduced (Every 10℃ raised,Battery lifetime reduces 30%)
◆ Storage Temp:-20℃ 40℃,Normally c ～ ontrolled within 0℃ ～ 40℃

Designing Lifetime
◆ Float Charge Lifetime:
NP Series less than 24Ah: 3 ~ 5 years(20℃ – 25℃)
NP Series more than 33Ah: 5 ~ 7 years(20℃ – 25℃)
◆ Cycle Lifetime:
NP Series cycle lifetime is 200 ～ 300 times(Power Battery can be upto 400 Times)
Charging Feature
◆ Float Charge:float charge voltage is 2.25 ～ 2.30Vdc/cell(25℃). Float charge correction factor is -3mVdc/℃.
◆ Cycle Use:Boost Charge Voltage is 2.40~2.50Vdc/cell, 25℃) . Boost Charge voltage temp. correction factor is -4mVdc/℃.
Charging current no more than (0.3C/A)
◆ Equalized Charge:Equalized Charge/pulse charge voltage is 2.30 ～ 2.35Vdc/cell(25℃).

Self-Discharge
At normal condition(20℃ ～ 30℃), batteries can store upto 3 months. Self-discharge loss is less than 3%/month.
