Frequently Asked by Distributors:
Is the BAT609 equivalent to the Bosch BAT612?
The BAT609 and BAT612 are the same size and use the same tools and chargers. Our BAT609 replacement battery is a drop-in replacement for both. Confirm your exact tool model and we’ll match the right capacity. It works as the Bosch 18V lithium-ion battery (BAT609 / tool battery) across the Professional range.
What is the MOQ for the BAT609 replacement battery?
Is the BAT609 drop-in compatible with original Bosch chargers?
Yes. The BAT609 BMS is updated with specific software so it works correctly with real Bosch chargers. The charging, authentication, and safety lockouts work the same as the original equipment manufacturer (OEM) pack. Handshake is validated on 100% of units at the end of the line.
Can the BAT609 replace the battery in my Bosch 18V cordless drill or power tool?
Yes, the BAT609 is a direct replacement for the Bosch 18V battery. It is used in professional cordless drills, drivers, grinders, and saws. If your tool uses the Bosch BAT-series 18V slide-on pack, the BAT609 is a true replacement battery for Bosch 18V power tools. It fits and works with the original equipment manufacturer (OEM).
Do you offer Bosch battery cell replacement, or complete BAT609 packs?
We supply complete, ready-to-use BAT609 replacement packs. We do not offer cell replacement or rebuild services. A new pack with fresh Grade-A cells and a new BMS is much more reliable than rebuilding an old Bosch pack. It also comes with full UN38.3 / IEC 62133 / CE documentation.
Which Bosch tools is the BAT609 compatible with?
The BAT609 is a direct replacement for the Bosch 18V Professional BAT-series platform. It has the same latch geometry as the BAT609, BAT618, and BAT622, and it fits the corresponding Bosch 18V Professional drills, drivers, grinders, and saws.
What cells and configuration does the BAT609 use?
The BAT609 uses high-quality 18650 cells (3000mAh each) arranged in a 5S2P configuration for a nominal 18V and a true rated capacity of 3.0Ah. Before assembly, cells are matched based on their capacity (±20 mAh) and internal resistance (±5 mΩ). You can specify your preferred cell brand (Samsung, LG, Panasonic, or BAK) when you place your order.
What protection circuitry does the BAT609 include?
The BAT609 includes a full-protection BMS: overcharge, over-discharge, short-circuit, and over-current protection, plus thermal monitoring. It matches the safety behavior of the real Bosch pack.
What is the warranty on the BAT609?
All BAT609 replacement packs come with a 12-month warranty against manufacturing defects. Every batch of products is shipped with the following documents:
– UN38.3 test report
– IEC 62133 certificate
– MSDS
– CE Declaration of Conformity
These documents are needed to clear customs worldwide.
How is the BAT609 packed for shipping?
