Well when you charge them the charge current goes down at the end as voltage potential gets smaller, best way if you don't have anything else is to make a discharge test, make a constant current discharge of 1A, when voltage gets lower then 3.2V (to be safe) note the time, if you hit 1A spot on then you have 3000mAh if it takes 3 hours for the voltage to go from 4.2V to 3-3.2V.

A quick reply, without re-reading the relevant posting: are you running this as root?

bogdanov_s | # 1524 | 2013-03-28, 16:39 | Report

yep as root

And you have the i2cget binary set as executable?

If not, "chmod +x i2cget" (if executed in same folder or set correct path to file)

Also, ensure that you don't have bq27x00_battery module loaded. You may unload it, by executing (as root):
/Estel

Hi Guys, The battery meter widget is showing long values since installing KP52 - was OK before. That offending battery module is not loaded as far as I can see. Any ideas?

Thanks
Giles.

@gilesn,
Not sure what you mean by "long values" but... could it be related to this?

In any case, this has nothing to do with home made batteries.

gilesn | # 1529 | 2013-04-09, 12:27 | Report

It's to do with dr_frost_dk's Battery Meter widget, see first post..

Long as in wrong! E.g. the % value is showing 3455090.6%.

FWIW, after last reboot the battery status in my status area said "no data or battery not calibrated". The same issue as reported in the post that I linked. Might your problem be a different face of the same thing? There it was blamed on KP52, here you blame it on the widget. But it looks like it's the status-area-applet-battery_1.0-5_armel.deb update that caused it.

In any case, mine fixed itself after a full discharge and recharge.
