Why are Inland replacement laptop batteries better? CAPACITY - Inland batteries use the same capacity battery cells as your original battery or better! Other vendors cut corners with lower capacity cells. QUALITY - Inland batteries use cells manufactured exclusively by the trusted brands Samsung, LG, and Sanyo. Other vendors use unbranded cells manufactured in China. SAFETY - Inland batteries are manufactured with a USA-made, Texas Instruments control chip. You are safer using an Inland replacement battery than one made with a control chip from an unknown source. LONGEVITY - The name-brand cells will last for double the length or better than knock-offs, exceeding 1000 charge cycles (compare to less than 500). WARRANTY - Inland batteries come with an unprecedented two-year warranty! We can offer this because our quality is far superior to the alternatives.
