The exact model is documented, but no direct pair statement is loaded. A platform rule may provide a conditional lead; absent evidence stays unknown.
Exceptions, source limits and safety
- Check the exact region, revision and current manufacturer instructions.
- Official page energy table (4 Ah / 48 Wh; six cells) conflicts with the voltage/capacity title; do not silently calculate a replacement Wh value.
A missing rating is not zero or universal support. Charger AC input and pack-to-tool use are separate checks.
