  2. 0. Background and Battery Service Process 1. 현 issue 및 기존 상태 - 배터리양불 판정 기준 및 Test 세부 기준부재 - batteryspec 다양화 : 고용량battery, 내장형 battery, High voltage spec battery 등 - 이로 인한 서비스 현장 배터리 test 난해및 불필요한 배터리 교체 발생 2. 목적 - 배터리양불 판정 기준 정립 및 표준화, 이를 통한 품질 제고 및 비용 절감 - 배터리 교체율30% 개선 ; 유럽 기준 3.5%  2.5% 3. Battery Service process 표. 2013년 1~8월 Global battery 교체율(북미, 일본 제외) Receive Battery Check IW/OOW Check customer abuse (Visual Test) Battery Test Test one more ReplaceBattery IW OK NG NG OOW NG OK OK Customer Approval No Problem 1/5

  3. 1. Cadex Test Procedure Prepare new battery(2~3ea) Step1. Prepare 2~3 good batteries(new parts). • Step 2. Register and set up the Battery SPEC to BatteryShop(=BS) • (BS is PC tool provided by Cadex). • In this time, you should refer to the Battery SPEC List provided by LG. Register battery to BS Step 3. Execute Adaptor Calibration (with Test Composition set for each battery type) Calibrate Adaptor/JIG Step 4. Select Best Battery through “Auto test” Test condition should be same with registered battery spec of Step 2. The result should be ; - Capacity : over 94% - Internal Resistance : meet spec Confirm Good battery Learn • Step 5. In BatteryShop, execute “Learn” with the selected best battery. • Setup Target Capacity(ex. 80%) • In the result of Learn, Capacity value should be over “94/47/0” %. Self-check (by QuickTest) • Step 6. Test “QuickTest” with the best battery which execute “Learn”. • If The result is over 94%, you can trust the result of “Learn”. • Step 7. From now, you can test customer battery. • In BatteryShop, • set up Target Capacity(ex. 80%) and select Station Program “QuickTest”. • Before test, clean the terminal of battery. QuickTest 2/5

  4. 2. The standard of Judgment and Caution • 1. The Standard of Judgment • a. Target Capacity : over 80% • b. Internal Resistance : generally 30mΩ ~ 250mΩ • If test result of Internal Resistance is not normal, • you should do Adaptor Calibration again or you can refer to the each model’s spec and range. • Refer to the Battery SPEC List. 2. Caution for Operation and Maintenance a. Whenever you change or shift the position of Adaptor, Cable, JIG and Cadex Station, you must do Adaptor Calibration again. b. If the result of “QuickTest” is bad(NG), you should check Test connection and the inserted status of battery in the Battery Holder JIG, and then test one more time. c. Change Pogo Pin periodically(3months) and calibrate Adaptor/JIG(weekly). d. Do Voltage Calibration - period : every one year - Voltage Calibration Kit : every 2 year, Calibrated by Cadex(send to Cadex) 3/5

  5. 3-1. Test Composition for External Battery Type 1. Total connection of External Battery 1-1. Components ② Battery Holder JIG (LG P/N : RAD32547861) ① Adaptor with Banana Jack (Cadex P/N : 07-110-0120) 1-2. Connect Adaptor and JIG to Cadex ② Insert Adaptor ③ connect Battery Holder JIG ① Cadex Station 1-3. Fix a Battery to common Battery Holder JIG ① Insert battery & adjust size ② connect battery +/- to Pogo pin ③ fix a battery V+ V- *.Cadex C7x00/C7x00C series 4/5

  6. 3-2. Test Composition for Embedded Battery Type 2. Total connection of Embedded Battery 2-1. Components ① Adaptor with Banana Jack (Cadex P/N : 07-110-0120) ② Board to Banana Cable Type 1. For VU, G, Nexus4 (LG P/N : RAD32547859) Type 1 board (LG P/N : RAD32547864) Type 2. For G2 (LG P/N : RAD32547860) Type 2 board (LG P/N : RAD32547865) 2-2. Connect Adaptor and Cable to Cadex ② Insert Adaptor ③ connect cable ④ connect Battery ① Cadex Station *.Cadex C7x00/C7x00C series 5/5

  7. Appendix. Cadex Test Procedure (Step 2) Step 2. Register the Battery SPEC ① Register and set up the Battery SPEC to BatteryShop(PC tool provided by Cadex). [BatteryShop] - Database > Battery models > Add > (Register the Battery SPEC) [Battery Model Name] • *. Example : BL-53QH • - Step by step, register the battery spec. • *. The screen of BatteryShop • ② When registering battery SPEC, you should refer to the Battery SPEC List provided by LG. • - Refer to the “Cadex Reg.
