Estry 24 V 3300 mAh Ni-MH battery for Hilti C 7/24 C 7/36 TCU 7/36 TE 5 A BP72 BP60

Direct replacement for Hilti cordless tools

This 24.0 V nickel-metal hydride pack delivers 3300 mAh and 79.2 Wh, matching the original specifications for Hilti C 7/24, C 7/36, TCU 7/36 and TE 5 A models. It fits part numbers BP72 and BP60 without modification. Overcharge, over-discharge, over-voltage and short-circuit protection are built in. The cell carries ISO 9001, RoHS, CE, UN 38.3 and MSDS certification.

Upgrade from lower-capacity Ni-MH packs

Users replacing a 3000 mAh or smaller 24 V pack gain measurable runtime for drilling and fastening tasks. The jump is worth it when daily work demands longer periods between charges or when the original pack no longer holds a full charge. No charger change is required; the existing Hilti charger remains compatible. The physical envelope at 200.7 x 111.0 x 104.66 mm and 1679.0 g matches the OEM footprint.

Capacity and headroom for sustained site work

At 3300 mAh the pack comfortably powers a full day of intermittent drilling in wood, metal and masonry before needing a recharge. Continuous high-torque applications such as large-diameter hole saws or extended screw-driving runs will deplete the charge faster. The 79.2 Wh rating places it within standard transport limits for air shipment. Builders needing multiple consecutive days of heavy use without mains access should plan for a second pack.
