Replacement battery for BlackBerry Curve and Storm

The Estry RCC51UW is a new lithium-ion cell rated at 1400mAh and 3.7V, matching the original equipment specifications for several BlackBerry handsets. It arrives as a single pack weighing 52.0g and measuring 51.3 x 37.1 x 7.46mm, designed to fit the existing battery compartment without modification. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Compatible models and excluded users

This unit suits owners of BlackBerry models including the 8900 Curve, Storm 9500, Storm 9530, Storm2 9520, 9550, Curve 8930 and Javelin that use part numbers BAT-17720-002 or D-X1. Buyers whose devices require a different voltage, capacity or physical footprint should look elsewhere, as should anyone needing a multi-pack or a higher capacity cell.

Critical spec: 1400mAh at 3.7V

The 1400mAh capacity at 3.7V delivers 5.18Wh of energy, which determines whether the battery can sustain the phone's typical usage time. Verifying that your handset lists this exact capacity and voltage is the single check that confirms the part is correct.

Questions about this item

What does the 1400mAh capacity mean for daily use in a BlackBerry Curve 8900?

The 1400mAh rating matches the original specification, so a full charge should deliver the same talk and standby time the handset was designed for.

What connector standard does the RCC51UW use and what limits does it impose?

The battery uses the proprietary BlackBerry contact layout for the listed Curve and Storm models; it will not fit devices that require a different pin arrangement.

Will the 51.3 x 37.1 x 7.46 mm dimensions fit the battery compartment of a Storm 9530?

Yes, those measurements correspond to the OEM battery cavity for the Storm 9530 and the other compatible models listed.
