Re: Battery Tests, Homemade 3000mAh XL Battery & Q&A (GOTO POST #1) SCUD is BACK!!!

You seem to have bq27x00_batter.ko module loaded. Search forum and disable it for good, it's depreciated, anyway.

I buy 2 scud from here.

I upload the actual items pictures and my Dual moddification.

Are they less thin than counterpart "regular" battery? Lucia Lui told dr_frost_dk, that those new blue dreams are going to have lower capacity...

Re: Battery Tests, Homemade 3000mAh XL Battery & Q&A (GOTO POST #1) SCUD is BACK!!!

original NOKIA BJ-5J batteries with 1741 respectively 1750 mAh ?!?
:confused:
i "calibrated" the batteries in my N900s a week or so back following Estel's steps and ended up with those rather unbelievable numbers :eek:

i know, i know, the SCUD 1350 mAh battery standard has 1500 mAh, but here i'm talking standard NOKIA BL-5J that came with each N900...

anyhow possible that those would hold 1750 mAh?

Re: Battery Tests, Homemade 3000mAh XL Battery & Q&A (GOTO POST #1) SCUD is BACK!!!

dr_frost_dk and other, who are experienced with many LiIons battery's types - I have small request.

I'm investigating different possibilities for "best" battery to fit into N900's body replacement. 18650 sounds like sane choice, although, of course, we're "losing" a little - at least, theoretically - due to cylindrical form, and size (thickness) pose some problems too.

Do You happen to know any type of "flat" battery, that is very popular (= no risk of it disappearing from market in any predictable time), offer decent capacity and quality/price ratio? Of course, I'm not talking about BL-5J variants - in fact, we're not even limited to Nokia's ones. As long, as it's possible to "get" into cell itself - stripping it from bundled protective pcb - it's good to go.

Of course, sane limits of size are close to N900 width and height - remember, designing custom body replacement, I can make battery socket (almost) whatever I like.

I would like to know, if there is any flat LiIon battery, that offer comparable, near, or better capacity per volume (inside our cover) and could be used in N900. Variants are free to include as many cells (paralleled) as needed, as long as it don't make N900 too thick (and don't alter it's wide/height).

Your output seems like towards full charged.
Please do the same for discharging and you will notice that your N900 "dies" with about 400-500 mAh left. Your capacity of 1741 looks like only one "full to empty" cycle.
You will need to recalibrate a few times. Recalibration starts from 2048/2056, when battery left out of N900 for few hours. And for each calibration (full empty with vdq=1) only 12,5% is cut. So just do a few more full "full to empty" cycles.

But the idea of a flat cell is still better then the 18650 because of the "lost" space, but the same goes for our dual battery's, there are loads of space in the mugen cover.

Re: Battery Tests, Homemade 3000mAh XL Battery & Q&A (GOTO POST #1) SCUD is BACK!!!

Would it cause problems if the original standard size battery is in the N900 battery bay and parallel to that a bigger capacity flat battery which just fits inside the Mugen cover? So two batteries with different capacity in parallel.

Re: Battery Tests, Homemade 3000mAh XL Battery & Q&A (GOTO POST #1) SCUD is BACK!!!

It was a general question about mixing batteries with different capacities. With my basic electric physics knowledge, there would not be a problem.

If the battery bay is left empty, quite much space is wasted then also.
