SK-8550 BATTERY CHECKER

1
Lead battery equipped with the vehicles is a kind of consumables which could be
exhausted accidentally or suddenly, especially in case of the weak maintenance condition.
Battery trouble is increasing in recent years by reason of a lot of car electrical devices, or
fuel-efficient systems such as start-stop system or braking energy recovery system that
could put an excessive burden on the battery.
Accurate and periodical battery check comes to be more important to prevent battery
trouble and to maintain the battery in good condition.
The most major roadside assistance is,

Vehicle battery has two types of internal resistances. One is "Rohm", the internal resistance
which contained in each battery. Another one is “Ret”, the charge-transfer resistance that
increases in direct proportion to discharge time of the battery current. For the weak
battery, "Ret" becomes higher and that makes the battery discharging time shorter.
Double Differential Pulse Measurement is specified to test the battery twice and input the
calculated "Ret" in the internal CCA calculation. By this method, SK-8550 can assure more
accurate testing than other CCA testers.
■What is CCA?
CCA stands for Cold Cranking Amperes. It is defined as the current a battery at 0°F
(-18°C) can discharge for 30 seconds and maintain at least 7.2V (for JIS, SAE and BCI).
And it is defined as the current a battery at 0°F (-18°C) can discharge for 10 seconds
and maintain at least 7.5V (for EN and DIN). The battery which has the bigger CCA, the
higher ability to start an engine, CCA is one of the criterion for selection of the battery.

■Temperature Sensor
Battery discharging characteristic should be varied according to the battery temperature.
For SK-8550, temperature sensor is embedded in the battery clip enabling to adjust the
battery test data to be under -18℃condition.
In-vehicle batteries are not always in full-charged due to the effects of driving condition or
fuel saving systems. If its charging level is weak, dischargeable CCA value becomes also
lower.
For SK-8550, CCA value corresponds to the charging level of the testing battery.
For testing the battery with low charging level and with low voltage, CCA test result also
becomes low as shown in the chart in the next page.
In another chart comparing measurement characteristics between new and weak batteries,
you can see the charging capacity goes down for the weak battery, and its CCA% value
becomes lower than the new battery.
■For lead-acid batteries, sulfation occurs when they are subjected to insufficient charging
during normal operation. The sulfation clung to the electrode plate can be the resistance
which decreases the battery power.
※What is “Sulfation”? : Crystallization of lead sulfate which occurs when discharging.

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（P-SOC※）, 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.
