BTRY PRI 66WHR 6C SDI LL14

Dell MM4H1 is a six-cell primary lithium-ion battery for compatible Dell laptops, providing portable power away from a mains outlet. It is identified as a high-capacity battery.

Its stated energy capacity is 66 Wh and output voltage is 11.1 V. The black battery has a thicker profile that protrudes below the laptop housing, a form that matters when checking whether it fits the laptop setup.

The listed compatible models include Dell Latitude 14 (3470) and Dell Latitude 14 (3460). The protruding high-capacity version is not suitable for use with a docking station.

For replacement in the listed Latitude systems, check that the extended profile can be accommodated. Its six-cell lithium-ion design and stated capacity help identify this MM4H1 configuration.
