Run those two command lines when your battery is fully loaded and you detach it from the charger.

Use your phone normally until battery starts to get almost empty.
Then run following commands again in xterminal window and leave it running.
# cd /usr/sbin
# bq27200.sh 10

Use your phone normally until battery goes fully empty and the device shuts down. You can connect the charger after the phone has shut down.

Now when you boot your device back up, you can see the true measured capacity of your battery by running:
# cd /usr/sbin/
# bq27200.sh

(One reason why it is this "complicated" is because bq27200.sh script has a bug; hardcoding i2cget path.)

i got this after the whole process. can u check it plz.and what changes shud i face after this. and thanks a lotttttttttttttttttttttttt.

If you did it by the instructions, then that is the current effective capacity of your battery when fully charged.

You could measure again and double check.

Also after couple of months you'll see the capacity is some smaller due to battery wearing out with time.

Would save from lots of questions and noise.

True. Technically, it should not be a problem - it just need *very* minor re-touch of bq27200.sh (to make it depends on ic2get package, instead of double-providing it), and proper Maemo packaging. To be honest, I thought about putting it into repos, just waited, if anyone request it

(so, basically, anyone else think it should be put into repos).

I'll get into Maemo packaging instructions again, later - I hoped to get up into learning it properly one day, and this easy, little (for packaging, of course - not to write it at the first place...) script is nice excuse for that

Warning! Possible quality drop of latest SCUD batch!

...or, it's just, that large quantity of fake BL-5J Scuds appeared on market. Still, My (received yesterday) shipment of 5 Scuds:
http://www.aliexpress.com/product-fm...olesalers.html
...bought from 100% trusted seller (*not* LuciaLui, though), turned out to be crappy 1200 mAh.

I'll post pictures of pakaging later - I'm now traveling, so I'll be able to do it no sooner, than on sunday evening - because there are subtle differences in packaging.

Also - what is more important - the battery itself is *thinner* than 1500 mAh scuds. It's of regular BL-5J battery thickness now.

I'm not sure, if SCUDians just decided to sell batteries of lower quality (my last shipment of "real" scuds got sticker with 2011.04 packaging date, this one is 2011.06), or I just bought fake Scuds - I'll try to check that.

Meanwhile, it would be great, if someone buying from LuciaLui lately, would be able to confirm/deny. Also, photos of such SCUD (especially, lower part with plastic cap) would help - I think I'm able to recognize, if it's 1500 mAh or 1200 mAh one.

Ps.

dr_frost_dk, I think it would be nice to add "Online Store 406982" to list of scammers on first page, as soon as possible.

damm that sucks, but unfortunately this is sometimes what you get with Chinese sellers, i have bought so much in the last many years, and when you buy something at start (or start of product coming on their list) then you get a good product, but buy the SAME product 2-4 months later then you get a really crappy product.

Estel | # 1040 | 2011-10-13, 10:28 | Report

I've updated last post with link to offer with suspicious SCUD's. I think we should add this seller to "untrusted" list. I'm not sure if it is seller fault or SCUD fault, but at least, we know that SCUDs from this seller are "bad", for sure.

If that would turn out to be whole SCUD quality drop, that would really suck - in such a case, I think that "christgift" would turn out to have best offer, considering ultra-low price. Still, I'm aware that it might be just fake SCUDs I've bought. One forum member from China said already - in this very thread - that SCUD is well-respected battery manufacturer in China, so there is still hope for good SCUD's somewhere

Meanwhile, I'm happy that I have quite high stock of full-quality Scuds already - from time to time, someone use my offer of assembling dual-scud or mugen backcover with camera lens cover (or both

) for a "donation".

So, I still can prepare a total of four "real" dual-scuds, for four interested people (or less, if anyone want more than 1 dual-scud).
