Direct Replacement Battery

The Estry Ni-MH pack matches the original Panametric KX-T3930 specification at 3.6V and 600mAh. It delivers 2.16Wh of energy in a 42.64 x 30.0 x 14.45mm housing weighing 63.3g. The cell suits cordless phones or similar devices that require this exact form factor.

Ni-MH Chemistry Limits

Nickel-metal hydride chemistry self-discharges faster than lithium types, so capacity drops if the pack sits unused for weeks. The 600mAh rating defines the practical runtime ceiling; devices drawing higher current will see shorter talk or standby times. Memory effect can appear if the battery is repeatedly recharged before full discharge.

Simple Two-Wire Install

Installation typically involves unplugging the old pack and connecting the new one to the same two-wire harness inside the handset. Polarity reversal is the most common error and will prevent charging or damage the phone. Verify the connector orientation and part number KX-T3930 before fitting.

Questions about this item

Which capacity should I pick for the KX-T3930 handset?

The replacement pack supplies 600mAh at 3.6V, matching the original specification for the Panasonic KX-T3930 cordless phone.

What does the 2.16Wh rating mean for daily talk time?

At 2.16Wh the pack delivers the same energy as the factory cell, so talk and standby times remain unchanged from the original battery.

What connector standard does this pack use and will it fit the handset?

The pack uses the same plug and polarity as the original KX-T3930 battery, and its 42.64 x 30.0 x 14.45mm dimensions fit the handset compartment exactly.
