Compatible replacement battery

The Cameron & Co DS-CS-CPD531SL is a lithium-ion cell designed for Coolpad 5311 and 7251 handsets. It matches the original CPLD-121 part number and delivers a nominal 3.7 V with a rated capacity of 1.65 Ah. The unit measures 71.00 by 58.73 by 4.21 mm and ships in black condition as a new, OEM-compatible replacement.

Users with supported Coolpad models

Owners of the Coolpad 5311 or 7251 seeking a direct-fit battery will find this unit aligns with the factory specifications. Buyers who need a different voltage, a higher capacity, or a battery for another brand or model should look elsewhere because this cell is built to the exact dimensions and connector layout of the listed devices.

Steady discharge profile

Lithium-ion chemistry provides a stable voltage curve throughout most of the discharge cycle, so the phone receives consistent power during extended talk time or data use. The 6.11 Wh rating reflects the energy available under normal load rather than a brief peak, and the slim 4.21 mm profile fits the original compartment without forcing the cover.
