Replacement Ni-MH battery for Craftsman tools

The Estry 34955 is a new 3.6V 600mAh nickel-metal hydride pack built to match the original specifications for Craftsman models 34955 and 34953. It delivers 2.16Wh of energy and includes overcharge, over-discharge, over-voltage and short-circuit protection. The cell measures 42.57 x 30.2 x 14.43mm and weighs 77.4g. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Suitable for owners of listed Craftsman devices

This pack fits users who need a direct replacement for part numbers 34955 or 34953 and want a certified Ni-MH cell with built-in safety circuits. It is not for buyers who require a different voltage, a higher capacity, a lithium chemistry or a form factor that does not match the stated dimensions.

Voltage and chemistry must match the original

The single specification that decides compatibility is the 3.6V Ni-MH rating; the replacement device must be designed for exactly that voltage and chemistry to operate safely and correctly.

Questions about this item

How do I install the Estry 34955 battery and what step is often missed?

Match the polarity markings on the 3.6V 600mAh Ni-MH pack to the device terminals before inserting the 42.57 x 30.2 x 14.43mm pack; the step often missed is verifying the connector orientation matches the original 34955 layout.

What maintenance or replacement will the Estry 34955 need later?

The 600mAh Ni-MH cells self-discharge over months of storage; recharge every 3-6 months to prevent deep discharge and replace the pack when runtime drops below useful levels for Craftsman 34955 or 34953 tools.

What limit appears first during sustained use of the Estry 34955?

The 2.16Wh capacity delivers limited runtime under continuous load; voltage will sag toward the 3.6V nominal floor and the pack will require recharging before the over-discharge protection activates.
