Compatible replacement battery

The Estry 6723DW is a nickel-metal hydride battery pack built to match the original specifications for cordless devices using part numbers 6723DW, 6722DW, 6722D and TL00000012. It delivers 4.8 volts and 2000 milliampere-hours for a 9.6 watt-hour energy rating. The pack measures 50.86 by 28.96 by 28.96 millimetres and weighs 181.0 grams. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are integrated for safer operation.

Thermal and power behaviour

Nickel-metal hydride chemistry runs cool during normal charge and discharge cycles, producing no audible noise and requiring no active cooling. The built-in protection circuits limit current and voltage to prevent overheating or deep discharge. Self-discharge is low enough that the pack retains usable capacity after weeks of storage. No external power supply or charger specifications are provided in the data.

Build integration

The rectangular pack fits the battery compartment of the listed compatible models without modification. Its 9.6 watt-hour rating falls well within typical transport limits for consumer electronics. Certifications include ISO 9001, RoHS, CE, UN 38.3 and MSDS, confirming compliance with quality, substance-restriction and shipping-safety standards. Buyers needing a different voltage, capacity or form factor should verify their device requirements before ordering.

Questions about this item

How do I install the Estry 6723DW battery and what step is often missed?

Power off the device, open the battery compartment, disconnect the old pack noting the connector orientation, fit the new 50.86 x 28.96 x 28.96 mm pack, reconnect matching the polarity, then close the cover. The step often missed is verifying the connector keying before forcing it.

What maintenance or replacement will the 4.8 V 2000 mAh Ni-MH pack need later?

Expect to replace the pack after roughly one year or when run-time drops noticeably; Ni-MH cells self-discharge so recharge every few months during storage and avoid deep discharge to maximise the 9.6 Wh usable life.

What limit appears first under sustained use of this 181.0 g replacement battery?

The 2000 mAh capacity sets the runtime ceiling; under continuous load the voltage will sag toward the 4.8 V nominal floor and the pack will hit its 9.6 Wh energy limit before any thermal or protection threshold is reached.
