Compatible Festool drill-driver battery

This 18 V lithium-ion pack replaces the original BPC 18 Li unit for C15, PSC/PSBC 400/420, Quadrive T18, Quadrive TSC55, T15, T18, T18+3 and Ti 15 models. It delivers 4000 mAh capacity and 72.0 Wh energy in a new condition unit. Builders who need a different voltage or a non-Festool platform cannot use this pack.

Capacity and voltage match

The decisive specification is the 18.0 V / 4000 mAh rating that matches Festool part numbers 498343 and 499849. A fully decoded chip communicates with the tool electronics exactly like the factory battery. Buyers who require a higher amp-hour figure or a different connector layout will find this unit incompatible.

Straightforward swap with common pitfalls

Installation consists of sliding the pack onto the tool until the latch clicks; many online videos demonstrate the process. The main issues are dirty contacts preventing charge recognition and using an unapproved charger that shortens cycle life. The pack reaches full performance after two or three complete charge-discharge cycles. Storage above 60 °C or 140 °F risks permanent damage.
