Hot Electronics Inc Replacement HP 672412-001, 709988-421, B4T74UA Battery for HP C2M11UA, Envy 17T, Envy DV4, DV6, DV7 Series

Old battery died leaving laptop unusable. This replacement was delivered a week faster than promised. It seemed a bit pricy but it was the highest capacity available (which I needed).

Exact replacement, as described. Longevitiy still yet to be determined (obviously). However, and fresh battery will add new portable life to an otherwise (usually overpriced when first purchased) older laptop system.
