The 5HTB0054B0A is rated at 930mAh and the Li-Ion cells are light and not subject to battery memory.  With the OEM replacement, you are guaranteed a battery that fits the phone and works as promised.

So whats wrong?  That sounds like an awesome deal. 

First, these batteries may have been actually Blackberry units but were A or B stock.  That covers a number of things regarding the source of the batteries.  They may be batteries removed from phones returned under warranty or returned to service providers.  It could be they are counterfeit from oversees and the supplier cannot verify they are authentic.  It may be that they did not pass Blackberry quality control and so may or may not have all the cells working.

The thing that concerns me is the number of online retailers buying these wholesale and then passing them off as new.  There is nothing to note they are not new stock other than the price.  A legitimate OEM Blackberry battery from a Blackberry Authorized wholesaler costs somewhere in the upper 20′s ($28 plus some change).

Any retailer selling the batteries well below this price is not selling you new, authentic stock.  Some may get discounts below the upper 20′s based on size but we don’t know of anyone getting them for less than 15% off that price.

Like most things in life.  If it is too cheap, it is probably not the real thing.  If you would not buy your Blackberry battery on Canal Street in New York, don’t buy it off the Internets version of Canal Street.
