How do I confirm this battery fits my Dell laptop?

Before ordering, remove your laptop battery (or check the underside label) and compare the model or part number with the listed compatible references. The 69KF2 is part of a family that includes closely related codes, so matching the model number prevents installation errors.

• Check your battery label for 69KF2, 8FCTC, 08FCTC, 70N2F, 070N2F, M59JH or similar codes.
• Compare your laptop model: XPS 15 9500/9510/9520/9530, Precision 5550/5560/5570, G15 5510/5511/5520/5515 series, Inspiron 7510/7610/7620, and selected Alienware M15/M17 series.
• If unsure, remove the existing pack and verify the printed part number before purchase.
