Todėl, kad pakrautas akumas duoda 13,6V įtampą, o maitblokis – tik 12V.
Tiesą pasakius MKN maitblokis nepakraus visai.

State-of-Charge in %

car battery.

Test the battery at room temperature. Allow 4-8 hour of rest after 
charge or discharge.

12.65V-100%
12.45V-75%
12.24V-50%
12.06V-25%
11.89V or less-Discharged
  	
Note: The BCI readings apply to flooded batteries with antimony doping. 
Calcium will raise the voltage by 5 - 8%. Calcium is commonly used for 
maintenance-free lead acid batteries.
After charge or discharge, allow the battery to rest for a minimum of 
eight hours before assessing the state-of-charge by measuring the 
terminal voltage.
