Dr. Battery MPL07212P-12 6-cell 11.1V 4400mAh laptop battery

Replacement battery for Gateway MX and M series

This 6-cell lithium-ion pack replaces original batteries in Gateway MX3400, MX3700, MX6000, MX6900 and a wide range of M-series notebooks. It matches the 11.1V operating voltage and 4400mAh capacity specified by the manufacturer. The unit is supplied new and carries a one-year warranty from Dr. Battery. It is intended for owners of the listed Gateway models who need a direct drop-in replacement.

Lithium-ion chemistry and smart-chip limits

The pack uses standard lithium-ion cells with an integrated control chip that manages charging current, discharge rate and thermal protection. This chemistry cannot be fast-charged beyond the laptop's built-in controller limits, and the chip will halt operation if a short circuit, over-current or over-temperature event is detected. Users must rely on the host notebook's own charging circuitry; no external charger or firmware update can alter these hard limits.

4400mAh capacity decides runtime

The 4400mAh (49Wh) rating is the single figure that determines how long the notebook runs on battery power. If your original pack was rated at 4400mAh, expect equivalent runtime; if it was higher, this unit will provide proportionally less operating time. Buyers who need longer runtime than 4400mAh delivers should not choose this model.
