Direct Replacement for Radio Shack Handsets

The Estry CS-0139 is a 3.6V 600mAh nickel-metal hydride battery built to match original specifications. It suits owners of compatible Radio Shack cordless phones who need a fresh power cell for daily talk and standby time. The single pack delivers 2.16Wh of capacity and includes overcharge, over-discharge, over-voltage and short-circuit protection circuits. Buyers wanting lithium chemistry or higher milliampere-hour ratings should look elsewhere.

Verify Model Number and Connector Fit

Check the handset label or the old battery for one of the listed part numbers such as CS-0139, SP516, SP-512 or 435506 before ordering. Confirm the physical dimensions of 42.57 by 30.2 by 14.43 millimetres and the 77.4 gram weight match the battery compartment. Ensure the connector polarity and plug style align with the original unit. This cell is not suitable for devices requiring a different voltage, capacity or form factor.

Drops Into Existing Charger Cradle

The pack fits the original charger base without modification and restores normal charge cycles. It frees the handset from shortened run times caused by aged cells and avoids the cost of replacing the entire phone system. No firmware updates or adapter cables are required. Installation is a simple swap once the compatible model number is confirmed.

Questions about this item

Does the Estry CS-0139 pack include a charger or only the battery?

The 1-pack contains just the 3.6V 600mAh Ni-MH battery; a compatible charger must be purchased separately.

How do I know the CS-0139 is the right version for my Radio Shack device?

Match your device model or part number against the listed compatibles such as SP516, SP-512, 435506, ET551, SP-503, 43-5502, SP807, 43-5512, 431083, CS-90016, CS-90017, SP-514, 435514, 431021, 435513, 43-5513, 433847, 43-1083, 433547 or SP-511.

What does the 2.16Wh rating tell me about runtime in a cordless phone?

The 2.16Wh capacity means the pack can deliver roughly 600mA for one hour; actual talk or standby time depends on the phone's current draw.
