Replacement Battery for HP ProBook and EliteBook

The Dr. Battery MPL08224P-22 is a new six-cell lithium-ion pack rated at 10.8V and 4400 mAh. It replaces original HP part numbers including TD03XL, TD06, TD06047, TD06051 and TD06052 across ProBook 6440b, 6540b, 6730b and EliteBook 8440p models. Buyers who need a higher capacity than 48Wh or a different voltage should look elsewhere.

Sustained Discharge Behaviour

The pack uses professional-grade cells and a built-in smart control chip to deliver stable output during extended use. Protections against short circuit, overheat and overload engage automatically when limits are reached. Lower power consumption and longer discharge time are maintained across the full cycle without sudden voltage drops.

Installation and Common Issues

The battery fits the listed notebooks as a direct swap; align the contacts and press until the latch clicks. Most problems arise when the original part number or output voltage is not verified beforehand. If the laptop does not recognise the pack, reseat it once and ensure the BIOS is current.

Questions about this item

Does the 6-cell lithium-ion pack run hot or draw extra power when the laptop is on all day?

The 48 Wh battery uses a built-in smart control chip that manages charging current and discharge rate to limit heat build-up during continuous use.

Must my HP EliteBook 8440p already have its original TD06051XL battery installed for this MPL08224P-22 to fit and work?

No — this replacement is designed to slot directly into the same battery bay as the original TD06, TD06047, TD06051 or TD06052 packs without any extra hardware.

Will the 10.8 V output work safely alongside the older 6730b charging circuit I still use?

Yes, the voltage matches the 10.8 V spec of the original HP batteries for the 6730b, and the onboard protection guards against over-voltage or short-circuit conditions.
