And your DSDT is reporting in watts. macOS/OS X requires amps. ACPIBatteryManager.kext cannot convert from watts to amps without correct voltage information.[/QUOTE]
Excuse me but how can i fix this problem ?

You need to fix your _BIF method so it reports correct design voltage.
In a pinch, you could probably use B1FV (which is currently used by _BST for "battery present voltage").
Read the ACPI spec for more information on _BIF/_BST.

Did you read the ACPI spec yet?

today I have read it , and I managed to fix a problem about power source, so now I can show if power adapter connected or just battery, but unfortunately I'm still unable to fix DesignVoltage = -1 so percentage is still always show 0%.
I attached my new patch, native disassembled dsdt and console .

What does the ACPI spec tell you about where "design voltage" is returned in the package result from _BIF?
And... once you answer that...
Do you see in your _BIF code where that value is set?

today I spent 6 hours reading , but I'm pharmacist and I never learned before something about computer and code...
I understand some things but it's REALLY hard for me to understanding all informations
anyway I changed the value in _BIF from Zero to 0x1DB0 ( battery is 7.6V / 5000 mAh) in the forth line , and I get working the percentage, I checked DesignVoltage in console and I found it = 7600
I don't know if this is the true thing I have to do or what !!
p.s in the console I get 2 errors I coloured them in red

These...

default 21:32:04.180237 +0200 kernel ACPIBatteryManager: getBatteryBIF called
default 21:32:04.180249 +0200 kernel ACPIBatteryManager: validateObject return 0xe00002bc

default 21:32:04.180278 +0200 kernel ACPIBatteryManager: fRealAC=-1, fACConnected=0

... mean the _BIF and _BST methods are failing (aborting). Most likely due to incorrect/incomplete patching.

ok these are the files , thank you

The files in ACPI/origin are 4 days old. Too old for comparison.
Read FAQ, "Problem Reporting" again. Make sure you press F4 in Clover (as clearly requested) before collecting EFI/Clover.
And you forgot ioreg.

As far as diagnosing the errors, you should instrument your _BST/_BIF methods in BAT0 (using ACPIDebug) if you think they are failing. They are very simple methods, so I don't see why they should be failing.

I think your patch for BAT1._STA is wrong. (you should not force it to return 0x1F... as there is probably no battery there). The errors are probably coming from BAT1, not BAT0. Because if you look carefully, it has no _BIF/_BST methods...
