myX-3 & myX-5
Test description
This test allows to test the various batteries.
Required tools
−
CADEX C7000 / C7200 / ASTRATEK
−
myX-3 & myX-5 adapters,
−
myX-3 Ammeter interface
−
myX-5 Ammeter interface
−
a voltmeter (minimum impedance 20 kΩ per Volt in DC).
Test procedure
13. Insert battery on ammeter interface
14. Measure the identification resistor between the Z poles :
15. Li-Ion batteries : 120kΩ Ω Ω Ω (tolérance = 117kΩ Ω Ω Ω - 123kΩ Ω Ω Ω , according to the surrounding temperature)
16. Measure the battery voltage between the V poles, the voltage shown must be between 2.5V and
4.5V.
a- If the voltage < 4v ,load the battery for 30 minutes with a travel charger and follow the instructions
below
b- If the voltage > 4V Measure the internal resistance with a CADEX or ASTRATEK batteries testers
Notice: Choose on the batteries tester ,the battery type (Li-ion) ,the nominal battery voltage (3,6V)
and the battery capacity (720 mA)
5. Read the result :If the internal resistance < 300 mOhms the battery is OK
