Direct Replacement Battery

The Estry JB950 is a 3.6V 600mAh Ni-MH cell built to match the original specifications for the Maestro JB950. It delivers 2.16Wh of energy in a 42.45 x 29.77 x 14.37mm form factor weighing 87.7g. Buyers needing a different voltage, capacity or connector will not be served by this pack.

Low Self-Discharge Operation

The chemistry provides stable voltage output with minimal self-discharge during normal standby or intermittent use. Integrated protection guards against overcharge, over-discharge, over-voltage and short-circuit events. RoHS, CE, ISO 9001, UN 38.3 and MSDS certifications confirm compliance with safety and transport regulations.

Sustained Load Behaviour

Under continuous draw the cell maintains its rated 3.6V level until the 600mAh capacity is depleted, then protection circuitry disconnects the load. The one-year battery-pack warranty period reflects the expected cycle life under typical duty cycles. No active cooling or external management electronics are required.

Questions about this item

How do I install the Estry JB950 battery and what step do people often miss?

Power off the device, open the battery compartment, disconnect the old pack, connect the new 3.6V 600mAh unit matching polarity, then secure the cover. The step often missed is verifying the connector orientation before forcing it in.

What maintenance or replacement will the Estry JB950 need later?

The 600mAh Ni-MH pack will gradually lose capacity over repeated charge cycles. Plan to replace it when run-time drops below your needs; no scheduled maintenance is required beyond normal charging.

What limit appears first during sustained use of the Estry JB950?

The 2.16Wh capacity sets the runtime ceiling. Under continuous load the pack will hit its 600mAh discharge limit and require recharging before other thermal or voltage limits are reached.
