Use your Bosch 18V PBA (Green) batteries on Metabo HPT 18V cordless tools, without buying into a second battery platform. Both run at 18V, so the adapter changes the fitting and not the voltage. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. Your existing batteries do more work, and there is no second ecosystem to buy into.

Why choose this adapter
- Your Bosch 18V PBA (Green) battery and Metabo HPT 18V tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
- Injection-moulded ABS, not 3D printed — no layer lines to split under load.
- Solid copper terminals, so less of the current is lost as heat.
- 5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
- Covered by a 12-month warranty from the day it arrives.
Bosch 18V PBA (Green) and Metabo HPT 18V compatibility
It works in one direction only: Bosch batteries powering Metabo HPT tools. For the opposite pairing, see adapters that run on Metabo HPT 18V batteries.
Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Bosch 18V PBA (Green) platform and that your tool takes Metabo HPT 18V batteries.
Important charging and safety information
This adapter is for powering cordless tools and nothing else. It cannot charge Bosch or Metabo HPT batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Bosch 18V PBA (Green) battery.
How it works
-
1. Use the battery you own
Any compatible Bosch 18V PBA (Green) battery you already have.
-
2. Slide on the adapter
It goes where the original Metabo HPT 18V battery sits.
-
3. Click in and work
No tools, no wiring, no modifications.
Bosch 18V PBA (Green) to Metabo HPT 18V — Common Questions
Will this fit my other Bosch batteries?
Only Bosch 18V PBA (Green) batteries. Bosch also sells Bosch 12V, Bosch 18V GBA (Blue), and those use a different socket — same brand, different rail and contacts, so they need their own adapter. Compare the rail on your battery with the photos before ordering.
Will my Metabo HPT 18V tool run as long on a Bosch 18V PBA (Green) battery?
Runtime comes from the battery, not the adapter — a 5.0Ah Bosch 18V PBA (Green) battery lasts roughly twice as long as a 2.5Ah one, exactly as it would on its own tool. The adapter’s copper terminals and heavy-gauge wiring are there to keep resistive loss low.
Could this damage my Bosch 18V PBA (Green) battery or my Metabo HPT 18V tool?
Used with undamaged, compatible equipment it is not expected to. Bosch 18V PBA (Green) batteries are lithium-ion with a protection circuit built into the battery, and it keeps working through the adapter — it stays in the battery and never moves into the adapter. Stop when the tool slows noticeably rather than running the battery flat, and stop using the adapter if it becomes unusually hot or the contacts look damaged.
Can I charge through the adapter?
No, and it should never be attempted. The adapter carries power one way only, out to the Metabo HPT 18V tool — there is no charging circuit inside it. Connecting it to a charger puts the battery, the charger and the adapter at risk. Always take the Bosch 18V PBA (Green) battery off the adapter and charge it on its own charger.
Does it work with third-party Bosch batteries?
Usually. What matters is the socket, not the badge: if the battery slides on and locks the way an original does, the adapter takes it and the Metabo HPT 18V tool runs. Aftermarket moulding does vary, so if yours looks unusual send us a photo and we will check before you order.
