@djibattworkshop Hi again..

ّI programmed the chip but the problem steel alive..

the voltage is hi but the Soc doesn't change or change so slow..

but when i use it on the laptop(z510,z500),even it has for example 0% it works such a fully charged battery..with both battery i have test it..

for example laptop works for 2 hours or more with high contrast and playing film..

We must found the problem and i know we can do it...

How to solve this problem.

1. Put the battery in laptop.

2. Connect AC charger.

3. Wait until battery 100% charged

4. Profit

@djibattworkshop I did it for 4 hours but nothing happen ...

after 4 hours it is 0% ..

laptop does not turn on by battery and the adapter must plug in to be able to turning on..

after turning on in that situation , laptop can be go on by battery,

the firmware problem is steel alive..

Could you send this battery to our workshop for repair?

@djibattworkshop hi again,No i can`t do it because i`m so far from you..

Is there any edited firmware that you could send it to me??

thanks a lot..

I programmed my battery from another Lenovo battery which has 3 cells,battery works properly but with 3 cells ,it charged quickly and discharged like a 3 cells battery about 90 - 100 minute with hi usage..my problems must be come from a firmware bug..

i can`t edit the firmware so if you can please give me another file which i can program my battery and give you the result..

 please note that FIRMWARE and DUMP are different things. Firmware contains chip instruction microcode, its protected by checksum and could be edited only be firmware developer.

You could check on Lenovo official webpage if they released updated firmware for your battery model, if so you could update it to latest version in the laptop.

The dumps with edited parameters have been already sent to you.

Initially your battery had the following issues:

Design Capacity - 43732mAh

Charging Current - 449mA

Me have been asking you to paste updated snapshot after FIX2 dump is applied to check if these parameters are fixed.

@djibattworkshop thanks for helping me..

can you tell me how much should be the minimum voltage for any cell in this battery?

maybe i should discharge it until the minimum voltage , then charge it until full..now i have a problem so i can`t send you snapshot,but after reprogram the chip with the second dump , i discharge it until minimum voltage 3000 mv , then i charged it by the device z510 , it charges until 81% , and after that it shows charging icon but nothing happened , so i think we should discharge it until the minimum voltage , what do you think about it?

help me..thanks👍

it charges until 81% , and after that it shows charging icon but nothing happened

What is cells voltages at 81% of charge?

And what is Current() and ChargingCurrent() at 81% of charge?

so i think we should discharge it until the minimum voltage , what do you think about it?

Yes, you could try it. But Sanyo firmwares calibrate RSoC at full charge when tapering conditions are reached and FC bit is set. Then chip recalibrate the RSoC to 100%.

You could read this thread how similar issue was resolved. It was 3S2P battery with bq8055a Sanyo chip. It also had Design Capacity and ChargingCurrent issues, after reflashing and charging to Full issues were fixed.

@djibattworkshop the voltage of cells at 81% is 4.15 volts..

i didn`t check the current..

@djibattworkshop would you please give me the  L09S6Y01_bq8055a_Sanyo_EEP1.zip password?

I want to check it on my battery..

thx...

this is the process from 0% and discharge..

it takes more than 1 hour but no percentage 

Now problematic parameters are fixed and complied with datasheet

 Design Capacity is 3350mAh

 Charging Current is 1622mA

Charging Tab also looks Ok, real charging current is in range 1500...1600mA.

RSoC 0% is typical for any Sanyo firmware after reflashing and SoftReset the chip. It will be recalibrated to 100% after full charge event reached.

The issue with your battery is unbalanced cells. Do you see message at the bottom of dynamic data?

It shows "Poor balance", and the deviation is 140mV. With such a big difference battery could not be fully charged. One of the cells reachs 4.20 level first then goes to unsafe area because another cell is just 4.07 volts. 

That's why your battery could not be fully charged and reach 100% level. It does not mattery how long it will take 3 hour or 10 hours in the charger. You should balance the cells manually to same level. Then start charging.

This is a dump for 3S2P battery.

Its not good idea to reflashing it to 4S PCB, it will never work properly!

Like @djibattworkshop said, this is the issue:
