I would be more suspcious of the hardware you're using.
My Dell boxes with mfi(4) seem to do just fine with failed batteries:
bash-4.2$ sudo mfiutil show battery

The write cache is disabled as expected, the issue is just the battery status reporting.
BBU State of Health output as added in r219717
switch (stat.battery_type) {
case MFI_BBU_TYPE_BBU:
printf(" State of Health: %s\n",
stat.detail.bbu.is_SOH_good ? "good" : "bad");
break;
}
and I suspect this would report "bad" for those batteries.
Does this still occur after r219717? I no longer have access to this hardware (or a bad battery) to test. Hopefully someone else can. I've asked a former colleague (who still has access to this hw) to test. I no longer have access to any of this hardware, but I believe this has been fixed. |
