Replacement battery for Teledex Opal DCT1905

This Estry Ni-MH battery pack replaces the original BATT-OPL unit in Teledex Opal DCT1905 cordless phones. It delivers 3.6V and 700mAh capacity for reliable talk time and standby performance. The pack measures 45.1 x 31.4 x 11.0mm and weighs 56.5g for a direct fit. Buyers needing a different voltage or connector type cannot use this pack.

Practical limits of Ni-MH chemistry

Nickel-metal-hydride cells self-discharge faster than lithium types so the handset should be returned to its charger regularly. The 2.52Wh energy rating defines the total runtime available between charges. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are built in for safety. Users who cannot keep the phone docked when idle will see reduced usable time.

Capacity decides suitability

The 700mAh rating is the single figure that determines whether this pack matches the original runtime specification. Confirm the handset label shows 3.6V and the BATT-OPL part number before ordering. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. If the device requires a higher milliampere-hour value this unit will not meet the need.

Questions about this item

Should I choose the 700mAh version or a higher capacity for my Teledex Opal DCT1905?

The 700mAh capacity matches the original BATT-OPL specification for the Opal DCT1905. Higher capacities may not fit the 45.1 x 31.4 x 11.0mm compartment or work with the phone charging circuit.

What does the 3.6V rating mean for daily talk time on the handset?

The 3.6V Ni-MH pack delivers 2.52Wh, powering the Opal DCT1905 at its designed voltage. Talk time depends on the phone firmware and usage pattern, not the battery alone.

Is the BATT-OPL connector a standard plug or proprietary?

The replacement is built to the exact BATT-OPL form factor for the Opal DCT1905. It uses the original connector layout so no adapter or soldering is required.
