Информационное Руководство для Conrad Energy 12V Ah lead acid battery, 250226

 

Store batteries at dry, clean, well-ventilated are. Batteries can be stored at 0 35

Ԩ for 6 months 

with recharge. Recharge the batteries once if storage period exceeds 6 months.

 

  

 

1 Floating charge 
‹      Charging parameters 
—    Voltage 2.23 2.30V/cell (25 ) (set point of 2.25V/cell is recommended). 
—     Max. initial current 0.30C

10

 

—     Temp. compensation coefficient -3mV/ . Per cell (from 25 ) 
—     Voltage deviation allowed: ±0.02V/cell. 
&     Note  
1). The initial deviations of battery voltages in a group will reduce to a low level after a period of 
service, for example, after a half year. 
2). Effects of lower or higher voltages  

Higher voltage overcharge

Shorten battery life. 

Lower voltage under-charge

Low battery capacity and shorten battery life. 

2 Equalization charging 
‹      Parameters 
—    Voltage 2.35 2.40V/cell (25 ) (set point of 2.35V/cell recommended) 
—   Max. initial current 0.30C

10

 

—    Temp. compensation coefficient -3mV/ .cell (from 25 ) 
—    Voltage deviation allowed: ±0.02V/cell. 
‹       Condition of terminating equalization charge 

Charging current drop to 0.01C

10

. 

&      Note  

Only perform an equalization when  

·Discharge capacity 20% lower than nominal value. 
·Storage period more than 3 months. 
·Individual floating voltage less than 2.18V/cell. 
·Low capacity battery is found after 3 through 6 months’ floating service. 
·After one year of floating service. 
·Recharge after installation & before service. 
·Recharge after capacity test. 
3 Cyclic charging  
‹      Parameters 
—    Voltage 2.40 2.45V/cell (25 ) (Set point of 2.45V/cell is recommended). 
—    Max. initial current 0.30C

10

 

—   Temp. compensation coefficient  -5mV/ .per cell (from 25 ) 
—    Voltage deviation allowed: ±0.02V/cell
