Replacement battery for Latitude 5300 2-in-1 series

This 60Wh lithium-ion cell replaces part numbers MXV9V, 5VC2M, 829MX and 21CP5/57/78-2. It fits Latitude 5300, 5300 2-in-1, 5310, 5310 2-in-1, 7300, 7400, Inspiron 7300 2-in-1 and Inspiron 7306 2-in-1 models. The pack ships new with a 12-month warranty.

Sustained output at 7.6 volts

The 60Wh capacity supports typical workloads through a full workday without recharging. Internal protection circuits guard against over-charge, over-discharge and short-circuit events during continuous operation. Capacity retention follows standard lithium-ion chemistry over repeated cycles.

Thermal and acoustic profile

The battery runs passively with no moving parts, so it adds no audible noise to the system. Normal operating temperatures stay within the laptop's existing thermal envelope. Power draw from the wall adapter matches the 7.6V, 60Wh rating during recharge cycles.
