How did you test the Battery's mAh and voltage on the N900?

Since using two batteries, when I go back to my single battery the N900 won't power on and when I charge it the Nokia screen shows up without the backlight and vibrates for half a second, turns off then repeats over and over.

Putting the two batteries in boots up fine. Any ideas?

See Estel's guide here and very nice piece of scripts he put together called bnf.

Try turning it on, wait around 2 sec and then plug in the charger it should boot eventually. Why is this happaning I have no clue but mine was behaving similarly...

Maybe springs that holds battery in place needs tightening? Also, single battery could just got discharged beyond safe limit. Check it's voltage with multimeter.

Good point Estel, definately worth checking but that wasn't the case for neither of them on my device. The problem was gone since I flashed it to thumb from testing cssu.

Thanks Estell for bq27x00 scripts and tutorial on battery capacity measurement; you stated that after the first time running the bq*.sh script you can do anything except for turning the device off.

I'd like to know if we can also recharge the device in that time? I recharged to 100% and ran the bq*.sh once. Now if I connect the N900 to USB a few times (but not let it go 100%) it affects the measurement?

I've been transferring files over mass-storage (without disabling bme, so it definitely charged), without affecting VDQ. Yet, if You overdo it - for example, connect and disconnect many times, or charge for too long - VDQ will reset to 0, until next full charge.
