Questions about this item

Does the 12.0V 2000mAh pack fit the Craftsman 315.11538 tool without any adapter?

Yes, it replaces the original 130279001 pack used in the 11538 and 315.11538 models.

Will a charger built for the original 12V Ni-MH pack charge this 24.0Wh replacement correctly?

The replacement matches the original 12.0V 2000mAh specification, so the existing charger will charge it normally.

After installing the pack, how can I confirm the overcharge and short-circuit protections are active?

The pack charges to full voltage and powers the tool without tripping; abnormal heat or instant cut-off would indicate a protection fault.
