What to know before buying

Listing details to confirm

Listing details conflict: the title and capacity field say 12.0Ah or 12000 milliamp_hours, while a feature claims 15Ah and another claims 50% more runtime than other 12Ah batteries. The detailed specification lists 12 A amperage, and the model-number compatibility list is not fully consistent across the page. Warranty terms also differ, with a 3 Year Manufacturer detail and a 12-month feature claim. Confirm capacity, compatibility with your exact tool and charger, and warranty coverage for the selected listing before purchase. The listed 1.5-pound item weight also differs from a separate 9-pound battery-weight entry.

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller share falls in lower star categories. No written customer feedback is available here, so these ratings do not establish actual runtime, capacity, compatibility, or reasons for satisfaction or dissatisfaction. For a replacement battery purchase, the conflicting capacity and warranty claims matter more than the aggregate rating alone.
