We use the highest quality lithium-ion cells in our Asus R540LA batteries. Our battery cells are made by Samsung and the battery components are made by Texas Instruments.
Higher quality li-ion cells last longer, charge faster and weigh less than cheaper, lower quality batteries. Low quality batteries can wear out in as little as 3 months. Our batteries can last up to 500 charges, or roughly 5 years. We're so confident in the quality of our batteries that we offer a 2 year warranty and 30-day money-back return policy.
