Replacement Ni-MH battery for Sanyo cordless phones

This Estry 52311 is a new Ni-MH pack rated at 3.6V, 600mAh and 2.16Wh. It matches the original Sanyo specifications and fits models including 52311, 52189A, 52310, CLT-4ER, CLT-5ER, 29519A, CLT-6ER, 53304 and 29630A.

Verify the exact model number on your old pack

Check that the part number printed on your existing battery appears in the compatibility list above. The physical dimensions are 42.64 x 30.0 x 14.45mm, so confirm the compartment in your handset can accommodate that size. Ensure the connector orientation matches the original Sanyo pack. This unit is not suitable for devices that require a different voltage, chemistry or form factor.

Holds a steady 3.6V through long talk

The Ni-MH chemistry delivers consistent voltage across extended calls and days on standby rather than a brief peak. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits to preserve capacity over many cycles. Self-discharge is low, so the handset remains ready after weeks of light use. The pack is rated for one year of regular service.

Questions about this item

What comes inside the package and do I need any extra parts to install it?

The box contains the 3.6V 600mAh Ni-MH replacement battery only; no charger, tools or cables are included so nothing else must be purchased separately.

How do I pick the right version among the listed compatible models?

Match the part number printed on your original pack — 52311, 52189A, 52310, CLT-4ER, CLT-5ER, 29519A, CLT-6ER, 53304 or 29630A — to confirm this 600mAh cell is the correct fit.

What does the 2.16Wh rating actually deliver in daily use?

At 3.6 volts the 600mAh capacity yields 2.16Wh, giving roughly the same run-time as the original Sanyo pack in cordless phones or similar low-drain devices.
