Replacement for Avaya DECT Handsets

This Cameron Sino battery replaces the original power cell in Avaya DECT 3720, DECT 3730 and DH6 cordless phones. It delivers a capacity of 650mAh and 2.41Wh at 3.7 volts. The unit is brand new and carries ISO9001, RoHS and CE certification. Buyers needing a different voltage or a higher capacity for another model should look elsewhere.

Direct Fit With Pre-Installed Chip

The pack measures 47.00 by 34.00 by 4.60 millimetres and weighs 16.7 grams, matching the factory dimensions for a straight swap. A fully decoded chip is already fitted, so the handset recognises the battery immediately without extra configuration. No soldering or adapter cables are required. Installers without access to a small screwdriver set will not be able to open the battery compartment.

Low Heat And Protected Operation

Normal use produces minimal warmth thanks to the low 3.7 volt chemistry and built-in protection against overcharge, over-discharge, over-voltage and short circuits. The safety circuitry keeps the pack stable during long talk-time sessions. There is no active cooling, so the battery relies on the handset's own ventilation. Users expecting a cooling fan or thermal throttling data will not find it here.

Questions about this item

How long will the 650mAh capacity last on my Avaya DECT 3720 before needing a recharge?

The 650mAh capacity matches the original specification for the Avaya DECT 3720 and DECT 3730, providing equivalent talk and standby time to the factory battery.

Does the battery get hot during a full day of calls on the DECT 3730?

The battery operates at 3.7V and includes overcharge, over-discharge, over-voltage and short-circuit protection to limit heat buildup during extended use.

Do I need a special tool to fit this 47.00 x 34.00 x 4.60mm pack into my DH6 handset?

No special tool is required; the pack matches the original dimensions and many online installation videos show a simple swap.
