Physical Integration

The unit measures 89.42 x 102.17 x 88.74 mm and weighs 494.0 g, matching the footprint of the original pack so it seats securely in the tool's battery bay. A lithium-ion cell composition delivers 14.4 V nominal voltage and 3000 mAh capacity, providing 43.20 Wh of energy. No additional adapters or wiring changes are required for the listed Hilti models.

Sustained Output

Under continuous load the 3000 mAh rating supports extended run-time for drilling, driving and fastening tasks before recharge is needed. The integrated chip manages cell balance during prolonged discharge, helping maintain consistent voltage across the cycle. Users should allow two to three full charge-discharge cycles for the pack to reach its optimal performance envelope. Storage above 60 °C or 140 °F is not recommended.

Questions about this item

How long can the 3000mAh 14.4V battery run a Hilti impact driver under continuous heavy load?

Runtime varies by tool and load; the 43.20Wh capacity delivers roughly 3000mAh at 14.4V before recharge is needed.

Does the pack get hot or noisy during all-day use on a Hilti SFH 144-A?

Lithium-ion cells generate heat under sustained draw but contain no moving parts, so operation is silent; allow cooling between heavy cycles.

Which Hilti charger part number is required to charge this B144 replacement pack?

Use the original Hilti charger supplied with your SF 144-A, SFH 144-A, SID 144-A or SIW 144-A tool; the battery's decoded chip works with that charger.
