Estry 811 3.6V 700mAh standard battery

Direct replacement for VTech handsets

This Estry 811 battery replaces the original 3.6V 700mAh pack in compatible VTech cordless phones. It matches the factory specifications for voltage and capacity so the handset charges and reports remaining talk time correctly. The cell uses nickel-metal hydride chemistry and is supplied new with a one-year battery-pack warranty.

Compact Ni-MH pack with built-in protection

Measuring 47.0 x 32.0 x 11.5 mm and weighing 63.0 g, the battery fits the existing compartment without modification. Integrated circuitry guards against overcharge, over-discharge, over-voltage and short-circuit conditions during daily charge cycles. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for materials safety and transport compliance.

Low self-discharge chemistry for standby reliability

Ni-MH construction holds charge during long periods on the cradle, reducing the need for frequent top-ups. Normal charging current stays within the handset's original regulator limits, so heat and audible noise remain negligible. The 2.52 Wh energy rating supports typical talk and standby durations expected from the stock battery.
