What to Consider When Buying an HP Laptop Battery

When looking for HP Battery for your laptop, the first thing you should do is determine whether or not it is compatible with your computer, and then you should think about the components it is built of. It is also in your best interest to consider the power rating and the service life, seeing as how these factors have a significant bearing on its performance and longevity.

In addition, you should consider whether you want a replacement that is a brand-name product or a generic one, as well as whether you want a brand-new battery or one that has been reconditioned. Regardless of the one you pick, you should look into any available warranties and ensure that it complies with all relevant safety regulations.


When choosing a laptop battery, search for compatibility. Most are made for specific computer models and state this in their product descriptions. To ensure compatibility, you'll need to know your laptop's make and model number. If you don't have this information, examine the inside of your laptop's battery compartment while it's off and disconnected. The battery's shell has its part number.


Power rating is also significant. The battery's power is measured in milliamperes (mAh). Look for the largest mAh number for the longest battery life. Most new ones are 5,000 mAh.

Refurbished vs. New

Besides brand, consider whether you want a new or reconditioned laptop battery. Some refurbished ones are good and often cheaper than new ones, but buying them is risky because you don't know how old the battery is, and it may die abruptly. Many refurbished batteries don't have excellent warranties, so it may be worth getting a new one if you use your laptop often.

Service Life

Laptop batteries have a service life, or how long they're expected to perform optimally. One cycle is entirely draining and recharging the battery. Most can go through 300 to 1,500 charging cycles but may not maintain a charge afterward. Some computers include a built-in cycle counter, although free software is accessible online.


Consider the battery's material: Nickel Cadmium, Lithium Ion, Nickel Metal Hydride, or Lithium Ion polymer (Li-Poly). NiCad batteries are heavy and don't last long. NiMH batteries survive longer than NiCads, but not LiONs or Li-Polys. They're heavier and can't fully recharge due to the "memory effect."

LiON and Li-Poly batteries are the best choices if they're compatible with your laptop. They're light, last longer than NiMHs, and are a third lighter. They charge faster and are greener. Regardless of which laptop battery you buy, ensure sure the cells exceed Underwriters Laboratories' international safety criteria (UL).

Unbranded Versus Branded

Consider whether you want a brand-name or generic laptop battery. Many brands and generic battery firms receive their components from the same manufacturers, so it may not make a major difference. However, some brand name versions fulfill stricter safety regulations than generic ones, and some use distinct, higher-quality components. Some brand-name products have better warranties than generics. If a brand-name laptop battery and a generic one are mostly comparable, you may choose to go with the generic one.
