1. Set the red test pen on negative pin P Set the balck test pen on the other pins one by one Two pins of them will give you a same or similar resistance value gt 500 amp lt 900 The two pins should be D and C Identify SMBC and SMBD from the two pins by the detector s VC9808 _ Black wire gt pin8 Orange wire pind Coffee wire gt pin4 Red wire pint After reading above 5 steps users should know how to learn the pin definition of most batteries For the rest let us talk about the two cases 5 7 1 Over discharge 2 There is a CONTROL pin Go back to step 3 and we measure the voltage of each pin For example DELL WU946 Measure the voltage of each pin Pini OV Pin2 OV Pin3 OV Pin4 0 1 0 3V Pind OV Pin6 OV Pin7 OV Pin8 2 2V Pin9 2 2V Notice pin4 has a special voltage www i battery com cn After measuring the voltage of all pins we find one of them have a special voltage In this case we confirm the special pin is a CONTROL pin And then we use a jumper to connect the special pin to the negative pin and measure the positive pin again For example DELL WU946 Use a jumper to connect the special pin pin4 to the negative pin pin1 www i battery com cn wwvw i battery com cn Measure the positive pin pin9 again A normal voltage above 5 V is indicated If at this case the voltage is still below 5V2. the battery must have been over discharged 6 7 Then go back to step 4 step 5 That is all how to use the connectors If you still have promblems please feel free to contact us 7 7
3. User manual Universal Batterty Tester Tell you how to use the connectors Here are the 13 connectors for almost all laptop batteries Pin pitch 2 0 mm RR 5 Pin pitch 2 5 mm Pin number 5 pin Pin number 5 pin Pin pitch 2 0 mm Pin pitch 2 5 mm Pin number 6 pin Pin number 6 pin Pin pitch 2 0 mm mere Pin pitch 2 5 mm Pin number 7 pin PAIS Pin number 7 pin Pin pitch 2 0 mm epe Pin pitch 2 5 mm Pin number 8 pin ISS SS Pin number 8 pin Pin pitch 2 0 mm PS ie be bb Pin pitch 2 5 mm Pin number 8 pin Sas f Pin number 9 pin With an error proof Pin pitch 2 0 mm Perey Pin pitch 2 5 mm Pin number 9 pin ee Pin number 10 pin Pin pitch 2 0 mm Pin number 10 pin Before using the connectors we must prepare everything we need Tools 1 A digital multimeter 2 A small screwdriver Products and accessories 1 A detector 2 An adapter 3 A connecting wire 4 The 13 connectors 1 7 5 A jumper 6 A battery under test Steps 1 Check the pin number and pin pitch of the battery For example The battery of Lenovo T60 Pin number 8 pin Pin pitch 2 0mm Choose a matching connector For example The battery of Lenovo T60 We should choose RF 20 8 The picture as below Identify positive pin and negative pin by the digital multimeter Positive pin and negative pin are often placed in the ends of battery interface For example The battery of Lenovo T60 Se
4. nect the connecting wire to the detector Switch on the detector lt means Connect the detector to the adapter Connect the adapter to AC power Thirdly try to connect the coffee wire and the orange wire to the other pins Once the battery information can be indicated it means the correct connection has been available SMBC CLOCK pin is always next to SMBD DATA pin 3 7 For example The battery of Lenovo T60 Use the small screwdriver to fix orange wire on pin7 coffee wire on pin6 Few seconds later we can not see any battery information on the LCD screen Then we exchange the place of the two wires orange wire on pin6 coffee wire on pin7 Few seconds later we still can not see any battery information on the LCD screen Then we disconnect the coffee wire and re connect orange wire on pin6 coffee wire on pind Few seconds later we still can not see any battery information on the LCD screen Then we exchange the place of the two wires orange wire on pind coffee wire on pin6 Few seconds later we still can not see any battery information on the LCD screen Then we disconnect the coffee wire and re connect orange wire on pind coffee wire on pin4 This time the battery information can be indicated 4 7 The 2nd method Check SMBC and SMBD by a digital multimeter and then use the detector to identify the two pins Steps Set the multimeter at the gear of diode
5. t the red test pen on the last pin ping O the black test pen on the first pin pin1 A negative voltage is indicated In this case we exchange the places of the red test pen and the black test pen Set the black test pen on the last pin pin8 Set the red test pen on the first pin pin1 A positive voltage above 5V is indicated In this case we can confirm pin1 is positive pin and pin8 is negative If the voltage is below 5V the battery must be in two cases as following 1 Over discharge 2 There is a CONTROL pin In the next pages we ll sepcify the two cases 2 7 Remarks Some batteries have a couple of positive pins and negative pins For example DELL WU946 both pin1 and pin2 are positive both pin 8 and pin 9 are negative So we d better measure the voltage of each pin Generally speaking except for the positive pins the voltage of all the other pins should be OV However a few batteries have a CONTROL pin which have a positive voltage too and the voltage is different from the postive pin Identify SMBC CLOCK pin and SMBD DATA pin We have two methods to identify SMBC and SMBD The 1st method First we should know the definition of the connecting wire Black POWER Coffee CLOCK Secondly connect the balck wire to the positive pin and switch on the detector For example The battery of Lenovo T60 Use the small screwdriver to fix the black wire on the first pin Con
