Start-stop and braking energy recovery systems are essential for the recent vehicles
to improve fuel efficiency and to meet emissions regulations.
These fuel-efficient technologies tend to put a load on battery such as to use under low
charging condition

, or to take frequent discharging under engine ON and OFF.
Therefore, the battery with high-durability, high-power, and high-charging ability (quick
charging ability) are required for the vehicles with these systems.
Using normal battery for the vehicles with braking energy recovery system should
accelerate the battery weakness and could cause the battery-dead in a short period. For the
vehicles with start-stop system, normal battery cannot be used. Using the specified battery
to cope with the each battery model is required.
SK-8550 can test these special batteries accurately by using their own testing programs.
For start-stop system batteries, model database is available in the SK-8550. You can select
the battery model easily from the battery list displayed on the screen.

P-SOC (Partial-State of Charge) : Using the battery under low charging condition.
