Post #3: Battery Meter, Q&A & etc...

Before asking questions please look to Post #3 under Q&A (Work in progress)


News: You can measure the capacity of you battery your self via your N900 using some scripts (NOTE: Not the method the battery's in this thread was tested with, this was done with more consistent equipment)
impeham made a script to make the battery measuring much simpler get it here


This is a new Thread to sum up battery's bought from EBAY, DX and else where.
This is a thread to show people where to buy and where not to buy.

Update: Battery's are now sorted after capacity (Real) and will only display battery's that can be bought, update still in progress, also need a new confirmed source for SCUD.
Old results are in post #6

-------- List of whats next ------- Bought and waiting for delivery -----


---- Future Test -----


--- Testing with eqipment ----
I use a charger/discharger for RC systems, it gives the mAh value when it charges and discharges.
My procedure is to charge the battery for testing completely up, then discharge it completely down, this gives me the mAh when discharging, now i charge the battery all the way up again, this gives me the mAh again, now the results i post here are the best "score" the battery achieves.
All battery's are first subject to 5 charge cycles, this is to get the best result, it of course does only mean a gain of 5 - 20mAh but it still counts.


--- Video testing will not be done anymore since the mAh test is all that is needed ---
My video testing on the phone is done with videos converted to H.264 to the limit of what the phone can handle, and im using custom brightness level 3, which is brightness 160 so that consumes some power.


Spreadsheet of the battery's tested so far: (same order as above)
News: Now in color (RED = BAD, BLUE = OK, GREEN = GOOD)



UPDATE: have cleaned up the results, now no more video play length. The video test is still a good way for you out there to test your orig. battery VS battery bought elsewhere.


Winner battery so far is Scud blue DREAM 1460mAh@1530mAh from aliexpress.com
