Replacement Battery for HP ProBook Series
This 6-cell lithium-ion unit replaces original HP part numbers including 633733-151 and 633733-241. It fits multiple ProBook models such as the 4330s, 4430s, 4530s and 4545s. The battery delivers 4400 mAh at 10.8 V for 48 Wh of capacity. It is intended for owners of those specific notebooks who need a new power source.
Straightforward Swap with Basic Precautions
Installation requires releasing the latch and sliding the old pack out before inserting the new one until it clicks. The built-in smart chip handles charge management and provides short-circuit, overheat and overload protection. The most common issue is ordering the wrong variant, so verifying the exact model number and original part number beforehand is essential.
Limited to Matching ProBook Chassis
The pack only works with the listed ProBook series and will not fit other HP lines or third-party laptops. Its 10.8 V output is fixed, so it cannot be used in devices that require a different voltage. Capacity is set at 4400 mAh, meaning runtime is constrained by that figure and the notebook's own power draw.
