Battery Cycle Life is a test performed by most Li-ion cell manufacturers and is used to describe a laptop batteries expected service life. One Cycle can be described as fully charging your laptop battery and then completely discharging it.
Each time a laptop battery goes through a charging cycle, it loses its ability to store as much energy as it did from the prior charge. This is why your battery powered run-times gets short over time and will eventually degrade to 20-30 minutes of run-time. The typical lifespan of an average Li-ion battery is about 300-500 charging cycles, or about 1-2 years of use. Very inexpensive laptop batteries use cells that are designed to last no more than 1 year.
Our Max Capacity laptop batteries are designed to exceed 500 cycles and still deliver great performance! The graph below shows just how well Max Capacity batteries perform vs. OEM and Amazon batteries over 500 charging cycles. When compared against these other popular replacement batteries, our product really does shine. We are the first supplier of laptop batteries to publish these metrics about the cells we use in our laptop batteries, and with numbers like these we are proud to show them off! See the chart below.
Note: The graph above illustrates about 80% of original capacity after 300 cycles at an operating temperature between 77° F and 104° F (25° C and 40° C).
So what does this say about other laptop battery brands that do not provide this information? It probably says their product performs poorly. In fact, we see that most laptop battery re-sellers provide no performance data at all! They only use marketing feel good terms like “Grade A” cells which should really be a warning sign. Find out why in our other article “What does Grade A cells really mean when buying a replacement laptop battery?”
