Replacement Battery for HP ProBook Series
This 6-cell lithium-ion battery replaces original HP part numbers including 633733-151 and 633805 series. It fits ProBook models 4330s, 4331s, 4430s, 4431s, 4435s, 4436s, 4440s, 4441s, 4446s, 4530s, 4535s, 4540s and 4545s. Buyers with other HP laptop lines must verify their original battery part number before ordering.
Practical Limits of Lithium-Ion Chemistry
The pack delivers 10.8 V and 4400 mAh for a 48 Wh energy rating. Capacity will gradually decline with charge cycles and storage temperature. The built-in protection circuit stops charging if voltage, current or temperature exceed safe limits. It does not support hot-swapping while the laptop is running.
4400 mAh Capacity Decides Runtime
A 48 Wh pack typically powers a compatible ProBook for several hours of light workloads such as document editing or web browsing. Heavy CPU or GPU loads will drain it faster. Users who need all-day operation away from mains power should consider carrying a second charged pack or a compatible AC adapter.
