How much does a Hilti B22 battery rebuild cost?
A Hilti B22 battery rebuild typically costs 40–60% of a new pack — for the popular 5.2 Ah variant, that's from around €65. The final price depends mainly on the capacity you need. Below we explain what makes up the price and when a rebuild makes sense.
What drives the price
A rebuild replaces all the worn Li-ion cells inside the original battery housing with new ones, while keeping the BMS electronics and connectors. The price is driven mainly by:
- Capacity (Ah) — more cells means a higher cost. A 5.2 Ah pack needs more cells than a 3.0 Ah one.
- Cell grade — we use new Samsung, LG or Sanyo cells with real, rated capacity.
- Electronics condition — if the BMS or thermistor is damaged, the repair is included in the service.
Approximate prices for B22 variants
The ranges below are indicative — we confirm the exact price for your model before starting. Every variant comes with the same 12-month warranty and a 2–5 business-day turnaround.
| Hilti B22 variant | Capacity | Rebuild from |
|---|---|---|
| B 22/3.0 | 3.0 Ah | ~€56 |
| B 22/4.0 | 4.0 Ah | ~€58 |
| B 22/5.2 | 5.2 Ah | ~€65 |
Rebuild or buy new?
A new original Hilti B22 pack costs considerably more. A rebuild restores full capacity for a fraction of that, and you keep the original housing and full compatibility with your tool and charger. A rebuild is worth it whenever the housing and contacts are sound and only the runtime has dropped — which is the vast majority of cases.
What's included in the price
- Diagnostics of the electronics and pack assessment
- Replacement of all cells with new ones (Samsung / LG / Sanyo)
- Reprogramming and calibration of the BMS to the new cells
- Final capacity and safety test
- A written 12-month warranty
