Replacement battery for Hilti 24V tools

This Estry nickel-metal hydride pack delivers 24.0 volts and 2000mAh capacity for cordless Hilti models including the WSC 55-A24, TE 2-A and WSR 650-A. It matches the original B 24/2.0 and B 24/3.0 part numbers and provides 48.0Wh of energy for professional site work.

Ni-MH chemistry limits and certifications

The 24V nickel-metal hydride chemistry avoids memory effect but self-discharges faster than lithium-ion, so charge before each job. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certificates confirming safety and transport compliance.

Rugged housing with slide-on mount

The 148.25 x 92.3 x 72.5mm enclosure weighs 1327.2g and slides onto the tool base like the factory unit. Built-in overcharge, over-discharge, over-voltage and short-circuit protection helps the cells survive daily site abuse.

Questions about this item

Should I choose the 2.0 Ah or 3.0 Ah version for my tool?

This pack is the 2.0 Ah (2000 mAh) model; the 3.0 Ah variant is a separate part number listed for compatibility reference only.

What runtime does the 48.0 Wh rating actually give on a WSR 650-A?

At 24.0 V and 2000 mAh the pack stores 48.0 Wh; real run-time depends on the tool load and duty cycle.

Does the pack use the original Hilti slide-on interface or a different connector?

It is built to the exact mechanical and electrical specification of the original B 24/2.0 battery for direct fit.
