What to know before buying

Listing details to confirm

The listing is contradictory about chemistry: the details field says Lithium Ion, while the title and feature text say Ni-MH. It also describes Ni-MH cells as more stable than NiCd and calls the battery an upgrade over standard NiCd, so confirm the actual chemistry before choosing a charger or comparing it with your existing pack. Compatibility is a listing claim, not confirmation for every tool code. The details field also says “1 AAA batteries required. (included)”, which does not match the stated cordless-tool battery description.

Who is it for?

A good fit for

Dewalt 18V tool owners seeking a replacement for a listed DE9098, DC, DW or DE battery code.
Buyers who can verify the stated model compatibility and battery chemistry for their tool and charger.

Less suited to

Anyone who needs a confirmed lithium-ion or Ni-MH pack without checking the listing discrepancy first.
Owners whose tool or charger compatibility cannot be matched to the listed 18V codes.

Aggregate ratings lean positive, with most ratings in the five-star category, while a smaller share are three-star. This suggests generally favourable but not uniformly strong responses in a modest sample. Ratings alone do not explain experiences or confirm the claimed capacity, chemistry or fit, so those details still need checking for your tool.

Frequently asked questions

What chemistry is this battery?

The listing conflicts: its details field says Lithium Ion, while the title and feature text say Ni-MH. Confirm the actual chemistry with the seller before purchase.

Which tools does it claim to fit?

The listing names many Dewalt 18V DC, DW and DE battery and tool codes, including DE9098, DC9096 and DW9098. Treat this as a compatibility claim and match your exact tool and battery code.

What is included?

The package list states one 5.0Ah DE9098 replacement battery and one user manual.

Does it work with Dewalt original chargers?

The feature text claims compatibility with original 18V chargers, but the battery chemistry is inconsistent across the listing. Verify charger suitability for the actual battery chemistry before charging.
