This is a brand new HP ProBook 4320s replacement battery. There are two key components inside your battery pack to look for when buying a new computer battery. The quality of the HP ProBook 4320s battery’s lithium-ion cells and the quality of the computer chip set in the battery pack. This battery is built with the best components, not the cheapest.
This HP ProBook 4320s battery contains the very best Li-ion cells on the market from Samsung. An important specification to look for with rechargeable batteries is the mAh (mili amp hour) rating or Whr (Watt Hour). This battery is rated at 5200 mAh or 58 Whr. This is the highest rating available for a 6 cell battery pack. The higher the mAh rating, the longer your battery will run before it needs to be recharged again.
There are no compatibility issues if your existing battery is rated at 4400 or 4800 mAh or a lower Whr. Simply put, more is better. And yes, this battery is probably better than your original!
The other key component inside the HP ProBook 4320s battery pack is the computer chip set that contains the program interface with your laptop’s battery meter software and important safety features that monitors when to charge and stop charging your battery. We use Texas Instruments top notch components for this.
When choosing a laptop battery, cheaper is not better. Cheaper batteries use inferior Chinese cells that typically wear out in just 3 to 6 months. The main indicators of inferior Chinese cells are the low price of the battery and a lower mAh rating. Inferior batteries also use inferior computer chip sets inside that can lead to compatibility issues with your laptop. Although every brand of laptop battery is hand assembled in China, the key to getting a great battery is knowing what components are inside.
